[QUOTE="dmax1800, post: 845386, member: 68255"] I'm using Norma brass and Barnes TTSX and Nosler AB bullets in .270 and 300 win mag. For now I'm limiting my shooting distance to 400 yards. In the past I've weighed & sorted brass in 2 grain lots and measured bullet bearing surface & sorted in .002" lots. The bearing surface of the last batch of 270 bullets ranged from .687" to .697". I just recently started weighing bullets and found out that almost half were more than .1 grain more than the rest. Now if I measure these bullets than are within .2 grains (+ or - .1 grains), out of 150 bullets I may have only 20 that are within .2 grains and .002" in bearing surface of each other. I know that guys shooting 1000 yards do all this sorting. [B]My question is[/B]: how much difference in accuracy is all my weighing, measuring and sorting going to make at 400 yards? Is it really worth all the time sorting? Would you guess it could make a difference in accuracy of 1/2", 1" or 2" at 400 yards??? I know I could do some tests, but I think it would take a lot of ammo, primers and powder to do a conclusive test. I'm looking for some expert help so that I don't have to spend all the time and money doing some tests. Thanks. [/QUOTE]
