Mostly 308 and 6.5 CM. I have dies for 30-06, but don't shoot it much anymore. It just seems such a waste of powder to pour 58-60 gr in a 30-06 case when I can get the same results with 1/2 powder and recoil using 40-45 gr of powder in the others.
I shoot a fair bit of 9mm and 223, but can buy it cheap enough that I can't justify loading it.
I shoot a few other rounds, but no in high enough volume to justify it.
10 handgun cartridges and 18 rifle cartridges.
I am including a few that I rarely do anymore, like 6mm TCU and 7mm TCU, and .454 which I haven't loaded in quite some time.
Currently loading 18 handgun and 31 rifle rounds, plus 16 and 12 ga shotshells (blackpowder/brass hulls). I still have dies for 3 others that I quit. This came up a couple years back, and someone was running in excess of 75 different rounds!
