[QUOTE="J E Custom, post: 1406451, member: 2736"] At this point if I were you I would look for the most consistent primer With the same approximate Brisance. You can try going up to see where it leads you and also going down. It's like tuning you primer for optimum performance. An example of the difference it can make in some cartridges. I had/have a 7/08 that I spent a lot of time working up the best load for because it was to be used in Running Boar matches (Moving targets at 500 Meters) and I needed the most accurate load possible. There ended up to be only two powder choices and with Rem LR primers it consistently shot .058 to .073 groups @ 100 yards. SDs were averaging .09. I decided to try a match primer (CCI BR2) and the SDs came down to an average of .06 (Not very much) but accuracy average was from .051 to .063 (Again Not Much But A measurable difference @ 500 meters. Subtle changes may not show much difference at 100 yards, but if you chronograph and keep good records on group sizes it will pay off at longer distances. Again: I am no expert on primers, I just have lots of experience with them and can not settle for anything less that the best performance. (I need all the help I can get). J E CUSTOM [/QUOTE]
