When weight sorting new brass what is the allowed spreads you use? How many grains ?
 
sorting brass that way is good but remember that the brass has to be trimmed to the same length, and be from the same manufacurer/lot number and clean.
 
I recently sorted a bunch of 7mm Rem cases, Winchester brand. All had already been sized, and the primer pockets were uniformed and the flash holes deburred. Theoretically they were the same.

I ended up with 3 different batches of brass based on how they weight out. First is 226-228 grains, second is 230 grains, last is 232 grains. The lower weight batch had the most spread and the others were relatively consistent. The 230 batch was especially consistent.

I don't expect much difference from them in performance in real life, but I'll stick with one batch at a time when reloading.

Hope that helps
