I have a remington model 14 in 35rem and have not shot anything other than factory amunition in it. I think it should be a 1930's or 1920's vintage and I believe it has a 1927 date stamped in the barrel. How does the model 14 compare to the 336 in strength? Does anyone Know its designed working pressures? I believe that it was only chanbered for the 30rem, 32rem & 35rem cartidges. Is the 30rem a 42,000psi cartridge like the 30-30win? This is a 14 not the newer 141.
