[QUOTE="ARlife4me, post: 3058532, member: 105694"] And those create more muzzle blast that maintain pressure at longer lengths (going by ql info). For long barrels (24" and longer) using faster powders generally give lower velocities (ql referencing). Without tweaking ql inputs on any of my loads most exit pressures are over 12k easy and some @ 16k (even on long barrels). Not sure if I want to pull the trigger on those! Accuracy overrides efficiency by a fine line. Both are possible, but more by case design? [/QUOTE]
