James,
Have you ever measured the run out of your reloads? I was a bit skeptical about the whole thing until I started sorting ammo and shooting groups. I now check every big game round I load. I don't hunt with anything with more than .003" run out. I havea mauser in .25-06 that shoots .75" groups with ammo having less than .003" run out and 1.25" with stuff measuring .005" or more.
