I’m not one to chase velocity in my reloading, but I find myself doing it with my 30-40 krag. I have a very accurate load with 180gr Sierra RN and IMR4831 @1900fps. The problem is that my barrel is short and I get 250-300fps less velocity than what the books say the load should get. A tech from Sierra told me that the 180gr RN has a thick jacket and to get reliable expansion, impact velocity should be above 2000fps.

Ive got some loads loaded up with IMR4831, AA4350, and western big game, trying to reach around 2100fps
