What is your favorite primer?

[Freebore]

Each rifle load is developed using different primer to see what gives the best accuracy with a given powder,bullet for a given cartridge w/ minimal deviations. I have Federal, CCI, WLR, Rem on my shelves. I mainly find that with ball powders in short cartridges (7mm-08) the WLR work well. The large belted cases the Federals. The custom .22's CCI BR's.
Never tried the Federal gold match. I think I'll try them w/ loads I have if they work that well. There is room for them too on the self.
