Don't want to be too nit picky, but for shooting F class out to 600 yards at what bullet weight should I be clustering bullets by weight, ie, 167.4, 167.5, 167.6, 167.7, 167.8, 168.9, 168.0, 168.1, 168.2...


Have heard I could use all a range such as 167.8-168.1 without much detrimental effects on accuracy. But am trying to eliminate variable. Have 1000 bullets I can go through and sort by weight.

Input please? Thanks very much
