[QUOTE="Coyboy, post: 691351, member: 3733"] I have tried many things and came to the conclusion that there are a few that make a measurable difference. 1. The one BIGGEST accuracy improvement you can make is to tune your load into the center of a large accuracy window. Thus if your a tenth of a grain light or heavy, on powder charge, it makes little to no difference in vertical. (I consider .1 grains above or below my target weight acceptable with cases that hold over 65 grains of powder, I shoot for .05 grains on smaller charged cases.) And if your bullets vary in length, bearing surface by a couple thou, your at a sufficient bullet jump that it doesn't have a negative impact. 2. Brass prep/sorting will garner the biggest improvement if your looking for something to sort. This would include any process that makes your brass consistent including annealing. At one time I sorted bullets, in general match grade target bullets from the manf. are so close I deemed it unnecessary and my scores didn't improve when I did it. Bullet tipping may give you a slight balistic advantage, and a little more consistency, if done properly, but some bullets 6mm and 6.5mm I refuse to mess with. I have done the 180 berger and 175 smks. But as of late been skipping the process, seems when un-altered bullets hold 1/2moa vertical at 1000 yards it is almost pointless. Loaded round concentricity, I seat the bullet half way and back out turn the case between 90- 140 degrees and seat the rest of the way. I never measure them because i wouldn't care to think about how little it would actually matter if they ran out 1-2 thou. Amazingly enough I win and place pretty high in all the matches I shoot, when many of the guys below me fiddle around with there loading way more than I do. [/QUOTE]
