Martini

[atomicsauace]

Ive recently started to get interested in Martini rifles and actions. I see a number of them that have been converted to a wide range of calibers. Im particularly interested in one chambered for .357. Are these old actions strong enough for a modern round like that? What would the max pressure one of these actions would contain? Are parts for these rifles readily available?

Martin action rare strong action. They have been converted to a host of calibers pushing the 50 000 psi .. 303 british at 45000 psi, and the 45-70 top loads.

Again it is a 100 plus year old action and care must be taken!

It's a combination of pressure and cartridge diameter to watch out for. The 357 Mag or 357 Max would be handled easily.

as above; it is thrust on the receiver that you need to worry about with the qualification that the firing pin hole on most old actions (not just martinis) is large and needs to be bushed for modern smokeless loads. If you multiply the pressure times the square of the base diameter of the most powerful cartridge originally chambered, it gives you a number to compare with a proposed new cartridge

Aren't the 357 ones based on the cadet actions? The full size one would be huge compared to the 357.

Are there enough parts around that I could piece together my own?

not sure if you are planning a build on a small or large action .
Just finishing a 357 max on a cadet /small action thick side and its strong enough
if you are thinking large action there is a greener NOS in the EE with all its parts and even wood for a reasonable price and it will eject the 357 max a lot nicer than the small action
