[QUOTE="MNbogboy, post: 1730257, member: 18849"] If you have the time do an accurate volume sort of all of them. Some past studies showed only about an 80% correlation. Some better brands of brass ( ie; lapua, norma, Nosler) often come weight sorted to within a grain or two and their volumes correspond. I've done tests years ago on cheap Remington brass (30-06) with 6 grain variance in 50 ct. Volumes all over the place with light & heavy just the opposite of what was expected. In your case the volume check will give you peace of mind. Your testing will tell you what variance in volume you will accept in velocity difference. Marking each case near the case head with an electric etcher will help you keep track of them. Record weights & volumes separate. Refer to them to compare range & chronos results.
