[QUOTE="edward hogan, post: 1668498, member: 1341"] Fred Sinclair had a small Ibico bound manual on handloading and scope mounting, last published back in the early-mid 90s. There is other great info in the Precision Shooting Benchrest Primer, and no doubt, in the reloading book by the guy who did The Competitive AR books 1&2. I've never been looking for that last 5 ten-thousandths of group tightness, so never sorted brass by weight. Sinclair or Benchrest Primer discussed starting with a bulk lot of 200 or so and sorting brass to within 1-2gr of mean avg, with an over/under pile for each larger variant piece. Once sorted, you sort your mean avg pile and go to tighter weight tolerance keeping closest weights in specific firing order. Of course, after sorting, it's time to uniform primer pockets, deburr flash holes, FL size, and then trim; then you weigh again... Hopefully, out of 200pcs you get a decent number of minimal weight variants. Or, you buy Lapua... Lapua is not the panacea so many claim. I had a lot of 500pcs of .308win which had what I thought were very loose primer pockets. Heard later that Winchester primers are a tiny bit smaller in the OD and were problematic sometimes.... I had over 100 in that batch that were not tight enough for Win primers. Luckily, held onto them and didn't trash them... But, I do like Win LR primers... Oh well... [/QUOTE]
