I recently reloaded some 30-06 rounds with Nosler custom brass, 125gr NBT, & 52 grains of REL 17. In hindsight I did not seat the bullets to the minimum of .308 inthe case. I was trting to reach my lands. Ended up only .25 into case. All the brass has soot on the outside of the case indicating not enough pressure to seat the case in the chamber. Not a ruptured primer. Is this all because of my seating?
