[QUOTE="J E Custom, post: 1694666, member: 2736"] I prefer to stay within 1 grain batches. First I do a full length size and trim to the same length so that at least the outside of the cases are very close to the same. then I prep the primer flash hole on the inside to eliminate any fingernail or burr that might be there from the manufacture. Then I start weighing the cases, separating them into 1 grain lots ( Like 187.0 to 187.9 and if I get one that weighs 188 grains It starts a new batch from 188.0 to 188.9. I normally end up with at least 2 batches, sometimes 3. Also many times I end up with 3 or 4 cases that are well beyond the batch weight and I use them for setting different bullets for that rifle by sizing with the expander ball removed to make a very tight bullet tension and include them in my die set for reference. I also use the extra cases for test firing to check chamber dimensions and finish. (Nothing goes to waste). If you go to the trouble to weight sort, 4 or 5 grain differences don't warrant the trouble and will not give you the results you want. Some premium cases will be very close and normally only have two different batches, If that. J E CUSTOM [/QUOTE]
