In the my arsenal of varmint calibers, the list includes 243, 223 AI (two of them!), 223 (two of them), 204 Ruger (two of them), & 17 Remington.

I prefer to shoot the 204's, 223's, & 223 AI's. Due to the cost of reloading, the 223 AI's come out of the safe more often. I can buy 2000 bullets for the 223's for less than $140. Last year, they were $115/2000.

The amount of powder used in the AI's is almost identical to what I use in the 204. Unfortunately, from the sheer cost of metal, the 223 AI's will be on varmint duty this year.

I have also purchased another Savage FV12 with a 1:9 twist barrel, which will soon be an AI as well.
