I have just had an old 788 Remington rebarreled to .223 Remington. I bought 200 new Winchester brass for it. This weekend I was sorting brass by weight, and found an extreme spread in weight of 91.3 grains for the lightest case, to 95.1 for the heaviest case that I weighed. Is this common in .223 Remington brass that Winchester manufactures? The most common weight was 93.0 to 93.3 grains. I was really surprised by this amount of variation. Does Norma or Lapua brass have better uniformity in weight? NO wonder during the break in period my shot to shot extreme velocity spread was running almost 80 fps. Please advise me as this rifle is shooting darn good for the ammo that was being fed to it during the break in period. Shoot Safe, Shoot Straight......RiverRat | ||

A quick answer for you... The capacity of the case is more important than the weight. Don't worry about that minor difference your scale has indicated. | |||
