So, this is on topic but a different monster.
I have an 1896 krag in the original 30-40 krag. Is has been sporterized and the original barrel chopped from 30” to 22”. My velocities are almost 300fps lower than what the manuals say. 300fps loss from 8” shooting loads that are hovering around 45k psi.
I acquired the rifle in the condition it is currently in. It would have been nice to compare velocities before and after the barrel was chopped.
