Weighing Brass
Heck, you would be surprised at the number of Benchrest Shooters who skip sorting brass by weight.
But then the vast majority use Lapua Brass, which simply does not vary that much.
That being said, I still order my cases from Ron Hoehn, pre-sorted. Benchrest is still about removing variables, and this is one that is easilly removed. The only way you can ascertain if it helps your combination is by simple old trial and error.
Like Big Al said. If it makes you feel better, sort them. There is a lot to be said for feeling good...........jackie
