I'm starting to look at keeping my handgun and rifle rounds limited with a few exceptions. I'm like most, 22LR/9MM/357/45/223-556 are my typical rounds, but I have two odd ones, a Winchester Model 92 and a Ruger revolver, both in 38/40, and I have another Ruger revolver in a 41 magnum. I have a few 357 revolvers and I plan to add a Henry Big Boy in a 357 with the side gate, and I've yet to break down and buy a 10/22 takedown. Those are probably the next two I get.
I started adding rounds slowly from the local Academy, and then I broke down and bought two 300 round packs of 38 special from Palmetto. It got here quick, I was happy. The just under 7 cents a round for 22LR is from Walmart, that's for their 40 grain - 36 grain is a bit more. I haven't really added much 223/556, just watching it ease. Two of my sons wanted to go CMP in Talladega for one's birthday about 18 months ago. I paid almost 90 cents a round for 556. That was an expensive day, $27 a mag.
