I shoot thousands of rds. at p-dogs every year. Did it with a 223 until I got my first 204.
I have 2 at the present time, a Cooper varminter and a XR100 Rem. that is on it's second barrel. I shoot a lot of 17 HH and 20 VarTargs 2 of each but if I could have only 1 it would be the 204.
I like and use CFE223 and 32 vMaxs and sierra Blitzkings, both work great but the Sierras are more explosive.
I got 3500 rds out of the XR barrel but I don't baby them.
