For me the primers that are my standby are CCI, large and small pistol, large and small rifle in standard and magnum. Powders and in rifle my main ones are IMR in 4198, 3031, 4064, 4320 and 4350. There are also others that I use primarily for handgun that include Bullseye, Unique, 2400, H110 and as of late, Trail Boss.
