NEVER HAVE!! I suppose, for the benchrest boys, it might be a good idea. Better yet for this though is to use the same case fover and over, reloading it at the bench for each shot. Weighing cases is for people who have eliminated every othe variable, like bullet weight, powder weight, primer pocket depth, flash hole diameter, neck concentricity, case length, brass hardness, etc.

Also another thing I would add. If you are using cheap brass, I think wieghing is important. I consider the Remington brass I buys kinda meteocre brass. But if you use high quality like Lapua or Federal, I bet you won't see much difference. Also, I notice I see big group differences with the bigger the caliber. On my 22-250, wieghting seems to have little effect, but on the 300 Weatherby and 338Win, I do see a difference.

I am not good at playing follow the leader, so I like to test things out for myself, so I took the lowest wieght set of 300RUM brass and loaded to my favorite load and took the highest weieght set of brass and loaded the same. The groups didn't change much but the point of impact did as I predicted. Almost .5" lower for the lighter brass. The difference in the two sets of 6grains, which I find common for large magnums in Remington brass.

Never have, to be honest I never heard of weighing the brass.I'll have to see what differences there are in my brass.I would have thought if it's the same brand of brass it should be consistent.Thanks for the inf.Ruger Redhawk

Well it's got 'group therapy' in that the flyer named Pluto is under control at least.

For those that do, what weight should be kept? Heavier or Lighter?

Heavier or lighter? Well, I was shocked to find out of 200 pieces of brass, I had 5 main groups. I divided them up in grain groups. Meaning if they were within a grain of each of other, they went into that group.

As far as which one to keep, I ain't no 1000 yard benchshooter, so I don't cull brass like they do. So I keep them all. I just won't mix the groups. I do notice that each step I do in the reloading process tightens up my groups little at a time. Its a hobby for me, so what the hey.
