Larry Gibson asked for this information but I thought perhaps more of you might like to see it also.
This data was gathered in the Hornady lab and is psi - pounds square inch - except for the 7.62x54mm Russian ammo. It was tested in the Hodgdon lab and is cup - copper units of pressure.
.303 British - Mk VII 175 grain FMJ dated 1943 - 2498 fps - 50,100 psi
.30-06 - LC-44 162 gr. AP bullets - 2800 fps - 61,600 fps.
.30-06 - LC-53 (Korean War) - 150 gr. FMJ - 2740 fps - 50,300 psi
8x57mm - 197 gr. FMJ - 1945 - 2494 fps - 50,000 psi
7.62x54mm R Russian - 1945 - 147 FMJ - 2832 fps - 41,400 cup
If I get a chance for either company to test that 1935 8mm stuff I picked up last weekend, I'll post the results.
