Come on in Martini! Your cartridge is a bit small but we'll play with ya.
Rocy Raab, one of the admin guys is a 25-308 user. But I think he has the 25-308 in one hand and the martini in the other
I suppose only you good guys can have them both in the same hand.
Reportin' todays activities. Weather windy and snowy. How windy you say? Enough to push a 222 Rem 40gr Vmax 8" @ 200 with the wind only 15 degrees from the bullet's line of flight.
So I worked on makin' my winny shoot w/ Rumluvers RUM. With the weather so lousy I couldn't chronograph anything but made major progress anyway.
Been working on implementing an old ignition idea. Seems a lot of people tho't of it but no one does it. Guess its a secret. And I'll keep it that way for a bit.
Took all last evening an most of today to tool up for it. Tool up means scrounge around for objects that will serve the purpose though they weren't designed for it; pester the neighbors and make a couple of trips to town.
Finally got enough things put together enough to make things go bang.
Loaded up my first try. This is far enough out of the ordinary that first, I removed the scope (it would be hard to replace), next I secured the rifle to a shooting rest that I made with inner tube strips and a bunge cord across the butt and enough line to let me hide behind one of the big poplar trees in the back yard.
Well, she went bang and everything held together. It was a pretty squibby load, as it turns out, but I didn't know that until she went bang.
Armed with greater confidence I dumped in another 14 grains of 4831. This time I was like super man. I just held the rifle in one hand an reached around the poplar tree and let her rip. Bigger bang but no problems.
Then had to switch to 4831sc as 71 grains of 4831 filled 1/3rd of the neck. I had aready shot 74 gr 4831sc without my modification so 71 grains seemed reasonable.
Did the same thing. Shot her like a handgun from the other side of the tree. Bigger bang.
Lessons learned:
The idea works. Without the chrono I won't know whether it works well or not so well.
Neglected to use ear protection and noticed that the noise was reduced in a major way. The only other time I forgot to use the muffs my ears rang for a day.
Gained even greater appreciation for the Holland QD brake.
Will post more results when the weather allows the chrono to come out and play.
