Hot damnn- Test Results of 4 plastic cases.
Rem high base 3" case, with 600 gr Dixie hardened slug. Roll crimped with crimper in drill press. All 4 loaded with 90 gr of 4759. We have a winner. Average velocity of 4 -- 1938 fps Average pressure of 4 -- 14, 575 psi. tested with transducer test ing setup, in 30 inch barrel,In my 24" NEF I got 1800+. Cases fell out of his test chamber like they did out of my NEF.And with some cases I can get in 95gr, that I figured with my math would have 15k psi.So my math and developement is OK.And 4800 ft lbs, thats neat with plastic. Tom says this load will do in any gun that handles the 2 oz factory magnum goose loads that test about 13,600 to 14,000.And 4759 will give slower time to peak pressure, thus will be easier on cases than magnum goose loads or the hot factory Buckhamer slug loads I fired, that expanded cases as much or more than our 4759 loads.Ed |
i may have missed the post but what exactly would these be used for?
|
Big game hunting in modern shotguns, with
regular chambers, like the NEF Ultra 12ga slug gun or a Savage 210 12ga slug gun.Ed. |
Buckhammer 3 "factory loads are 15k psi.
A 2.75 inch case with 80 gr of 4759, a thin card wad, a 3/8 cushion lubed felt wad, when crimped is about 2.4 inches long, with 600gr Dixie slug. Based on pressures recorded in previous post for 3 inch case and 90gr of 4759, they will run about 13,400 psi, and work through modern guns.Another load tested with same bullet, 65gr of 4759, tested at same place was 11,800 psi and 1640 fps. So you don't have to put in my max loads, but go down a little and use in modern guns that are lighter than NEF so they don't kick so bad.But yet you can get fairly good energy levels for big game, 3300 to 4000 ft lbs of energy.Ed |
WE planning on a big action for 12GA FH.
Here is picture of top part of the first scale-up model, next to smaller Wickliffe. It has 12GA FH round in feed trough. It is aluminum just for a model. It will handle 12GA FH, 700HE, 700NE, 600NE, etc. Bottom of block is flat to set on mill table to do the machining.Next machining will be the hole and slot down through the action for breech block and hammer to slide up and down in.Its taken awhile to get some tooling.I had none when we set up vertical mill, and have to get more.The action model also will be narrowed up when finished, and contoured to look as good as the Wickcliffe.Ed. http://www.gunownerstv.com/su.jpg |
Tested the Wickcliffe with 12ga FH case
in a temperary chamber, just primer, to see if hammer with beefed up spring would fire bmg primers.I scalloped out the back of the action so 12ga cases would feed into the action and temp chamber They fired ok. But the extra stiff spring makes it hard to cock. We will have to work on that.The original Wickcliffe action that we want to scale up is tall enough so that when breech block is lowered the block clears the bottom a 12ga rim when cases slide out of chamber. So in the scale up we need to just add a a little width for wider breech block, and the bigger barrel thread, and keep the sides thick for strength.Ed |
Fired couple 3.5" cases with 90gr
4759 and 460 grains of buckshot, 14 number 1 buckshot.Fired in nef, pattern huge due to rifling, even with shotcup. They were going 2000 fps plus, and went through 1/8 steel on end of stand. Ignition perfect, extracted easy. In smoothbore be a real hairy load. With three 3.5" plastic cases with 100gr 4759, 600gr slug. Used .135 card wad, a 1/2" and 1/4" felt wads. 1900+ fps in 24" NEF barrel, same low pressure as the 3" cases we pressure tested. I have NEF chamber lengthened for our longer brass case so it does 3 & 3.5" also. A nice long barrel we'd have 2050 plus.Ed |
Here is pictures of the breech, lever,
linkage, etc, set up on a block to get the geometry for the scaleup model working ok.And setup measurements to make the breech hole in the action, in right place.Also used this model to get hammer and trigger set up to ride on the breech block. With a strong hammer and trigger in the right place in the guard.In the pics above you see the pin the lever pivots on. The actions being bigger will be wider than the levers;So the space on the pivot will be taken up by the Ruger style extractor on the left side and a spacer on the right side. Spacer also acts as a breech block stop at the bottom of the breech travel.So to get block stopped at right position for the diameter of the case and feed trough, we adjust spacer size. Ruger extractors from GP changed a little bit will do.Ed. http://www.gunownerstv.com/70.jpg http://www.gunownerstv.com/71.jpg |
Here is sectioned action with parts in.
Original action that had defects that I sectioned down the middle..I ground out the top to allow case to set higher, representing a the taller action that we will have due to larger diameter cases. That lever in the picture is the lever we will use with longer stroke. Also in the action layout is the breechblock, hammer, trigger with a 12GA FH in front, all in to check layout. This lever looks to be easier to fit and shape to bigger action and stock, with a good pistolgrip to handle recoil. Lever shape fits where trigger is better.Ed http://www.gunownerstv.com/hta.jpg |
I will be posting more research on this thread
about other powders in 12ga plastic cases,about the 12GA FH loads, about scaled up falling blocks, my 700HE long belted case, and the 28GA FH.Here is picture of some other cartridges I have with some of mine. 1st= 408CT, 2nd- T-rex necked to 416- 3rd- 600OK 4th- 510HE, 5th-585HE, 6th-700H 3.25, 7th-12GA FH, 8th-700HE. Last most powerful. Ed http://www.gunownerstv.com/chh.jpg |
Here is pic of the finished breech block model
for the scaleup action.You can see hammer and trigger mounted in the rear of the block.Ed http://www.gunownerstv.com/block.jpg |
Another shotgun/rifle experiment is 28ga FH.
Rocky MTN is making me some 3.25 in 28ga cases. They are good to 38k psi. That will get 500-550 gr out at 2500 in bolt action.A regular 28ga gun may get to 2000, depending on how heavy barrel is.Should average 17-1800. Just lengthen chamber. Get a NEF Ultra cut off leaving breech section for monoblock and have 28ga rifled barrel made and screwed or soldered in monoblock. And being able to hold 38k to match brass, That would get 2500 fps loads.Ed http://www.gunownerstv.com/28.jpg |
Here is picture of the first falling block
model of aluminum, with a roughed out stock to see how it looks. Action is a rough model. It shoulders nice, and lever is inlet into pistol grip, so you can't get banged up fingers with the big cartridges it is designed for, like levers that stick down at the guard.Ed http://www.gunownerstv.com/hfb.jpg |
I know you've been told this already. But you need to get it patented, so I can buy one. Looks good. Keep up the good work.
|
Here is pic of action model with lever open
and the breech block down. Also the action will have a slot in the top rear for a top tang of whatever length you need. Can even have long tang for tang sight.Ed http://www.gunownerstv.com/hfbo.jpg |
Here is pic of a double that I will put
barrels in, monoblock style, using the breech section for the monoblock. This one will be for 28GA FH. May get another same size for my 510HE. I will be able to run full pressures with these.....I am trying to find a bigger, heavier one to put 12GA FH in. I want heavier one so as to run pressures like my Savage as a minimum.Ed. http://www.gunownerstv.com/zab.jpg |
Had question about locking RMC cases onto
lead slugs, as they don't crimp into the grooves well as sharp bend works thick mouth. First I resize tight and slightly bell mouth.Insert slugs which take a little pressure. Then I use a die with slightly more taper and swage the mouth into slug, like the fit you get with bottleneck cases. Same deal works with our long cases made from BMG brass.Ed |
Preliminary testing with VV N-110 powder shows
it works with small primers like the 4759 powder, in plastic cases. Perfect ignition like the 4759. Starting loads are 60 gr min like 4759 for good ignition,600gr slug. In 2 & 3/4" plastic full load is 75gr with card and 1/4" cushion wad.In Nef 24" bbl 1700fps. In 3" plastic 87gr, card and 3/8" wad, 1800 plus. In RMC brass case. 100gr, card and 1/2 wad 1900 plus. All running same safe pressures as 4759 lab tested. So that is two powders that are slower than shotgun powders, and much safer to work with for regular primers, giving at least 20% more velocity. Ed |
Along with the two slower than shotgun powders, IMR 4759
and VV N110 that ignite reliably with shotgun primers, that are easier to load for slugs, in heavy bbl can get 20% plus more velocity, I've found another. It is IMR 7383 $3 a lb surplus. Tested plastic 3" cases, perfect ignition with regular primers. 8 types of cases,600gr slug starting load 100gr. Full load 140gr giving 1800 fps plus in 24" bbl NEF.With loads halfway between start and full didn't even have to resize to shoot again.Full load just has a card wad under slug in 3" plastic.Wad just tight on charge, as no extreme compression of powder needed. Will do heavier slugs and RMC brass cases. Ed |
Tested 730g with 7383. Perfect ignition.Extracts easy.
130gr gives 1650 plus fps in 3" plastic. Tested 800g slug with 7383 in plastic.Works good. Have question about different cases and dies. The RMC cases use a shotgun primer, thus they have a real thick base. They are not a thin headed, balloon headed case, and RMC makes sides thick enough for regular 12ga wads. But in a break action the 3" plastic cases with our 4759, VV110, 7383 loads are close to RMC in power. Can buy a hundred plastic for price of one RMC. 3.5" chamber 12ga with plastic is as good as RMC for 3" And if I shot RMC in Savage to get more power, which I could do as far as the firing process, the expansion above the base, due to being a turned case would make extraction stiff, causing extractor to damage rim. A turned rim will not take what a drawn one will. Rcbs set should do RMC easy.Ed |
Tested 870gr hard slug with 7383 in 3"
plastic. Over 1500 fps in NEF short barrel. I wish it had a longer 32" barrel.......... The folks at 50 Cal suggested we write up a piece on the 12GA FH. Interested in what we did to make hairy cartridge using 50 cal brass adapted to the 12 gauge shotgun platform. A job for Rob to do? His wild idea has been viewed about 400,000 times in the forums we put it in.Ed |
Found another powder that works with small
primers in plastic and RMC cases, w/600gr slug. It is IMR 4227. Ignition perfect, same load levels and velocities as 4759. Powders slower than shotgun type, that ignite properly with small primers(shotgun-lg rifle); we found 4759, VV-110, 4227, 7383 surplus, the latter a slow powder that also works with real heavy slugs Pressure tested 7383 with heavy powder load. 870 gr with 128 gr of 7383-- All that could be put in REM plastic and keep length to what would feed from magazine of a 3" gun, after it was roll crimped with tool in drillpress. 1513 fps-- 14700 psi. That is a slug 50% heavier than factory Buckhammer at little faster speed and at little less pressure. Ignition perfect, cases fall out. Love that $3 a lb powder.Ed |
Finally able to make the
longer barrel improvement on the 1887 12ga levergun....... Rifled and heavy and 31" long. After many months finally got a barrel.Ed http://www.gunownerstv.com/87up.jpg |
With NEF. Plastic cases, roll crimped slug
in drillpress. 82gr IMR 4227 1650 fps, with 730gr, 78 gr 4227 with 800gr, 1600. Expansion on cases show little more pressure as full loads of 4759 and 600gr. Ignition perfect with small primers. Ejects cases fine. Burns clean. Got a GEHA bolt 12ga to put a heavier rifled barrel on to test. Ed |
Tested 870 gr in NEF with our long
brass case with big primer.I have NEF with extra hammer spring for big primer. Got 2000 fps and still able to extract case. Would do little more, extractor needs to be wider and set up positive. Used 260gr of WC-860 and MagPro. Could use RL-22, Rl-25, Retumbo, etc. That's 7700 ft lbs.. I get 600 gr slug to 2300 plus in NEF, long case. so you can go light or heavy.Ed |
More testing with 4227. Greg got little over 1500 fps in
3" plastic with 870 gr slug using 74-75 gr of 4227. I did the same. This compares to much lighter REM Buckhammer slug, we have more speed. Almost all the way through 5 ft bundle hardwood boards. I have Mossy 695 as well as GEHA 12 gauge to put heavy rifled barrels on. And my 87. Will be checking Mossy 395 for a guy who wants to put on a heavy barrel.Here is pic of 695 bolt action Mossberg with dinky barrel and the heavy long rifled barrel for it. Ed http://www.gunownerstv.com/moss.jpg |
I tested in NEF 3' cases, Alliant 2400 with
small primers, Fired ok at 75 deg but when case cooled there was majority of misfires and squib loads. Don't reccomend it.. Here is picture of Mauser 12ga bolt action GEHA next to a heavy barrel like I will put on it Make a good slug gun.Ed http://www.gunownerstv.com/geha |
The 12GA From Hell, 700HE, and
700HE 3.25" is now on Ammoguide, the last page of cartridge list.Recent news says H&H is going to build Paradox Shotgun/Rifles.Ed http://ammoguide.com/?catid=611 |
We tested 3.5" plastic cases in NEF, small
primers. My chamber is lengthened for our long brass case, so they work fine..... With 600 gr slug, 105 gr of IMR 4227, got 2100. Same slug, 180 gr, 7383 surplus, got 2100 fps. That's 5800 ft lbs from plastic shotgun cases.Ed |
Here is the Enfield I reamed out to feed 12 gauge and BMG
size cases. I added two rear bolt locking lugs, one the huge bolt handle and another added that locks in rear bridge. The front lugs still contact on their top 40 %. This is concept from earlier shown Mauser shotgun conversions, where they were made from 98 Mausers, giving a bolt action 12ga.This one is chambered for my belted 700H 3.25" case, as a load developement test gun. Loads up to 825 gr at 2500 so far. Ed http://www.gunownerstv.com/325b.jpg |
Damn nice qwork your doing there, and I agree with the others you should patent this asap!

The three From Hell cartridges----
My 28GA FH, 2nd Our 12GA FH, can you guess the 3rd?. What do readers think. Ed http://www.gunownerstv.com/8fh.jpg |
Would #3 be the....OTKLAM round?
(owwwww-that-kicks-like-a-mule) |
It is the 8GA From Hell, a real cartridge. 4.3 inch long
brass case. 8 ga shorter plastic case, plan on in same chamber. The brass kiln gun case isn't as long as mine. Where do you find the rare 8 ga brass kiln gun cases. Looking now for guns or actions and barrels. I make it from 20mm Suzy brass(20mm Hispano Suiza), by putting on a 8ga size rim and reshaping like we did 12GA FH....Ed |
8ga, we gonna do a couple, first one a test
gun in an Enfield with rear locking lugs added. All locking is in the rear, it is not exactly like my 700HE one,as both lug seats gone in the front like a Mauser 12ga shotgun. May have a way to get barrels 'fast'--- fast being like 2 weeks, from the time I have money to do it. And only about 150 bucks each.......Am working on it. In pic you see long case sticking out of the action, a couple 8ga plastic cases, a couple of the 8ga kiln slugs, 3 oz and hardened. Am looking for a slug built like the Federal 10 ga one that has rounded nose and hollow base, that fits bore tight, for smoothbore. The barrels I am working deal on will be smoothbore.Ed http://www.gunownerstv.com/8fhe.jpg |
Had a light barrel 87 12ga replica now
it is this Long Tom slug gun.....Ed http://www.gunownerstv.com/87L.jpg |
Got an 8ga barrel blank being made now,
will be here end of the week.Found this info on plastic 8ga kiln gun loads, they load a frangible 710gr slug at 2300- for 8300ft lbs, load 1275gr hard slug to 1700, 8100 ft lbs. We will outdo those easy with our non-shotgun powder loads, in a heavy barrel. We setup an Enfield for 8ga. In the 87 long barreled gun we will be testing Breneke slugs. Guys are reporting good accuracy in smooth and rifled barrels. The pictured barrel on 87 is smooth and we will see how the slugs in pic stand some speed.Ed http://www.gunownerstv.com/bren.jpg |
Tested 35" smooth barrel in 1887. Got couple
1 oz foster slugs over 2400, with 110gr of 4227. 3" plastic case, regular primers. This is a heavy barrel for that type of load, don't do this in your 12ga skinny barrels. The 28GA FH cases on the way.Chambering bolt gun for it now..Ed |
In the 87 long smooth barrel got
1 oz Brenneke to 2400 with 110gr of 4227, You could use 4759 and VV110 also at lesser amounts. Barrel is cylinder bore size. Brenneke slugs need no wads as the locked on wad works good.Ed And going heavier in 87 got 600 grain Dixie over 2000, got a Buckhammer slug I took out of factory load over 1900. Buckhammer and locked on wad is 630 gr. Tested in 3" plastic cases. The firing pin on the 87 didn't protude out like I like them to as it comes from factory, so I removed .015 from the hammer stop. It fires big and small primers perfect.Ed |
10GA FH..a NEF 10ga, medium to heavy wt smooth barrel.
28" long, gun weighted to 14lbs. Factory FED 765gr loads are 1300 fps. 200 gr of first powder tested is 7383 surplus and the regular shotgun primers got 765 gr to 1600, for 4300 ft lbs. Case won't hold anymore 7383. Federal factory hollowbase slug is .025" smaller than 10ga bore. I bumped it up to the .775" size, by expanding hollow base. With 7383 that gave another 150 fps.Fast starting shotgun powders expand base better than much slower 7383. The Federal factory load has 120gr of wads/seals about 1.4" long. Better to replace with much more slower powder, getting better velocity, still at low shotgun pressures.Ed We will test 4227 with the same slug , and saboted slug of some design. We roll crimped with crimper in drill press. Case expansion with 7383 very little(.006") like the factory loads. 3.5" plastic.Used one .050 wad.Ed |
