I'm a little new to rifle loading. I'm loading a 178 gr Hornady A-Max with 15.8 grains of IMR 4198. My rounds were a little to long and a few were catching on the rifling, they shot fine, and I don't see any signs of over pressure on the case. I had to lower the bullet .060 deeper into the case. Should I worry about blowing up my gun or should I be fine? :confused:
UPDATE: Primer pocket is not expanded but the primers from the fired cases that were too long are flattened a little bit. I think I'm going to have to pull 90 rounds. :(

If there is load data to support there charge, compressing powder in itself is not a problem. Compressing powder is very common and preferred by many.

Hodgdon list IMR 4198 as "compressed" for the 180gr Spree SP.

Seating deeper and getting farther from the lands will in most cases "reduce" pressure not increase it.
