Just wondering if there is anyone that long range shoots on animals that weighs there brass? Is it that big of a deal on accuracy? And if so, what grain ratio do you stay in? Like 1 grain difference, 2 grain so on and so on? Reason I ask is I am planing on having Leupold make me a set of turn knobs for my 270 WSM. As of now it shoots less than a 1/4" moa. at 100 yards. Haven't measured it yet but 2 in the same hole and 1 bout 1/8" away.
