Tried to get back but there was a problem on the site.
Some answers to several questions about the Martini Cadet:
The Cadet action is technically a BP action for a BP gun. However it was made in the era of smokeless powder. It is much stronger than 99% of the folks realize. It is as strong as the large action, however it is limited by the "turn" and that is you must have a cartridge that will go into the chamber, past the rear height of the action or bolt. One indication of just how much pressure a Cadet action can handle is the cartridge designed specificly for use in the Cadet, the 222 Remington modified with a rim or the 222R. I own one of these rifles and it is a 222 that you load as normal using a 38spl shell holder, very simple. But the gun uses standard 222 loads and the 222 case itself is rated as a 60K case, normally loaded to 46-47,000 CUP which is exactly how the 222R is loaded.
I believe that the largest diameter case head you can safely load in the Cadet is the 225 Win or 30-30 due to the chamber VS barrel minor thread diameter. There are a lot of 225s around and as with mine, the folks that own them stick to factory loads or equal and do not push the limits.
The secret to the 357 Super Mag guns is the use of rifle bullets as a flat sided pistol bullet will not make the turn into the chamber. You must also reduce the firing pin diameter and make a bushing to reduce the firing pin hole for high pressure cartridges. I use a small short bushing (about half way through the bolt face) with a shoulder, inserted into the bolt face with black locktite, firing pin hole drilled first. I create a shoulder on the firing pin and stop the FP on the bolt body, not the bushing. Make sure to shorten the pin so it does not extend past the standard smokeless extension. I also change the firing pin spring to a new spring just in case its old spring is worn.
The 357 SM guns, or Max if you wish have 16 inch barrels and both load as follows:
180 Hornady SP Rifle Bullet 24.5 Gr H-110 @ 2,140 fps .70 group at 100 yards this is a max load with slightly starting to flatten primers
200 Remington RN Rifle Bullet 23.5 H-110 @ 2,003 fps .50 groups at 100 No pressure signs at all
The 180 load is a bang flop load on a deer. It is a Bambi roller.
I just knew Paul would understand the idea of the 358 Win in a #3, expecially when new wood was added to the equasion, with a recoil pad.
The #3 was made in 30-40 Kraig, a buddy of mine has had two and still has one. He like Paul is a #1 nut and decided his life was not complete without a full set of #3s. He has a #3 he built is 45x120.5 that is an uncut cylindrical case at its full length, the extra .5
The #3 and #1 actions are identical, save the levers and lever parts. If I can get it to post I will show you my #13. A #3 22 Hornet with a #1 7mm RM barrel, #1 wood and a #1 mag extractor / ejector.
Here we go,

First is the 2nd 357 SM
