Whoo man - you need to see if you can still find some .223 DogTown bullets that Midway used to sell. Vaquero turned me on to them. Somewhere there are videos of Orbitup shooting a rabbit out of my rifle with them. It looked like a grenade went off in its belly. The ones I used were 55 grain flat based and were super accurate too. I've still got a box of 500 I haven't opened yet. I think they were made by Speer.Same.
During the years when the dogs are few and longer range I'll lean heavy on the centerfires. In the years of plenty, the 22lr has duties out to +-125yds.
