I read that it is unsafe to fire .308 Winchester in an Ishapore 2A1, since it is chambered for 7.62x51, and the brass on that is thicker than .308, which could blow out.
I also read that the pressure limit on the 7.62x51 is lower than the pressure limit for the .308, but I read elsewhere than this is a misconception, and that the pressure from the 7.62 was measured using CUP and the .308 was measured using PSI, and that they are actually almost exactly the same. The problem is the headspace. On the 7.62 the headspace is larger and the brass is thicker, so firing the thinner .308 can lead to an explosion.
If I get an Ishapore I would want to fire .308 loads from Federal or Hornady. I don't reload.
Also, is the AIA Enfield chambered in .308 or 7.62x51?
