[QUOTE="J E Custom, post: 368747, member: 2736"] Maybe I can shed some light on this subject. First= On Quality brass it is not nessary and if you open the hole up larger It will hurt accuracy and SDs. Most bench rest cartriges use the small rifle primers with small flash holes to get a hi velocity jet effect that burns the powder more consistently. And to answer your question on why they even make a tool for this purpose, Flash holes are made in the brass several ways,The quality brass is normally drilled and the less quality brass is punched. The punched flash holes will some times have a finger nail of brass on the inside that should be removed and if you use the uniformer you should use the smallest size that will fit the largest of the holes(They will vary so only remove what is nessary to make them the same). "Uniform". It is like anything else in reloading "Less is normally better". J E CUSTOM [/QUOTE]
