[QUOTE="entoptics, post: 1443157, member: 104268"] Thanks for the tips, although it seems a bit like I expected...Everyone has a slightly different opinion on priority order. For perspective, my rifle is a Savage LRH 300 WM with a Shilen Select SS barrel. Other than the barrel, it's bone stock. Scope is a Sig Tango4 6-24. Brass is neck turned Norma (± 1% weight spread total, usually sorted into 0.25% groups). Necks aren't all the same length, as it arrived WAY short, and the forum advised me [I]not[/I] to trim them all to the shortest, but I sort it into batches of ±0.001" for loading anyway. Powder is hand weighed to ±0.000, so only error there is in the scale. I'm now about 25 groups into load development, and my spreadsheet says 1.01 MOA overall average of 4 shot groups. The reason I asked about loads, is the "minus flier" (best 3 of 4) column says 0.53 MOA. Seems like I get an awful lot of tiny 3 shot groups with an ugly flier. The rifle also doesn't seem to really like any particular seating depth or bullet. I only run the 210 class, and have tried ELDM, ELDX, Berger VLDH, and Nosler ABLR in 0.03" increments from touching the lands to 0.09 off. As an example, the ELDM has printed a 0.6, 0.8, and 1.1 MOA group, all at 0.030". Similar results for everything else give or take a tenth of an MOA. [SIZE=14px]I think I'm gonna quit chasing "perfection", as my hand loads are probably not the limiting factor achieving "all day long" 3/4 MOA shooting. Perhaps it's the stock, perhaps the shooter.
