Has anyone ever found a vast velocity or accuracy spread from non-crimped loads with wide variances in trim lengths???
I recently accidentally primed a bunch of .223 brass that I trimmed on my Lee trim kit. Over a batch of 300 rounds, the trim variance goes from 1.760" (max OAL)-1.740" (.010 under the trim length). I was going to trash this brass, but now that I've primed it, I'm trying to decide whether to write it off. I've sorted it into lots by trimmed length, so the box by box extreme length spread isn't more than .003".
I never crimp on my .223 loads due to the high powder density,so should I trash it, load it as blasting ammo, or load it up with decent bullets and not sweat it?
