    How do you do it, groups within a grain or two. Does this help for shooting 300yds and under. My rifle is a 308 if that helps.

    Measure the brass on a scale to within IMHO .5 gr. But for 300 yards - this may be a wasted process unless for a benchrest comp.

    :confused:

    trim to uniform length. weight goes to capacity which affects pressure. crimp also changes pressure. and the neck thickness also affects neck tension. having fun yet?] 300 yards is like Envisaged says.

    collect cases of Federal Gold Match that are shot in your gun. trim them once to min LOA just keep reusing them.
    good luck

    Brass weight gets lost in the noise at 300 yards. For 600 yards and beyond, it can be worthwhile.

    Can't hurt but don't scrap the 'out of bounds' stuff unless it's grossly over/under weight.

    Having a nice batch of consistent brass makes load development a lot easier. You have eliminated one of the big variables, pressure differences.

    Or you can buy Lapua (if available in your caliber of choice) and not worry about it. They make very consistent brass.

    I bought a 100 cases in .308 Win (Nosler Factory 2nds) About a year ago. All case weights were +or- .25 grs it was trimmed to 2.005", chamfered case mouths, uniformed primer pockets, and the flash holes were all .081" and the case necks were a uniform thickness, and concentric :)

    A benchrest competitor will start with a hundred cases. Weighing is generally the first step, and half of the cases will be rejected at that point.

    If you are a benchrest competitor shooting a benchrest rifle, then it matters, even at 100 yards.

    But you're not, and you don't, so it doesn't.

    HTH!
