[QUOTE="Montana'eer, post: 2116726, member: 113417"] Can't say I'm an expert but this was interesting (to me). I bought a box of Hornady Match ELDM ammo to break a new rifle. I chrony'd the last 2 5 shot strings. Accuracy at 100yds was great, but ES 63 and SD22. Pretty crappy I think. My loads were using virgin Peterson brass, using the same bullet as the Hornady and those ES/SD numbers nose dived. The best was 5/5 (although accuracy was not great). The more velocity the smaller the ES/SD. I did basic brass prep- I ran them through the die expander ball, chamfered and dry lubed prior to bullet seating. That's it. I have yet to reload that once fired brass. I know it could be a number of factors- powder, brass, primer differences, but the Peterson brass is really consistent (weight wise). I've got Peterson brass for 3 calibers right now. [/QUOTE]
