ZR,
Missed your earlier post, I see more clearly now.
I use the .22 LR in a rifle and pistol for pure trigger time. I have been using the .223 in a 16" barreled AR and a 22" bull barreled Handi for predators here in TX. Handi liked the WWWB 45 gr hps, AR likes the rounds a little heavier and both do the job. The .223 is used in the pdog towns out to ~400 yd, wind does influence accuracy. When I was a teenager back in TN, I used a Brazlian 8mm Mauser for ghog and crow hunting out to about what i could see one at and mostly hit what I shot at inside 200 yd. Sure wish I'd had a .22-250 or .223 back then with a good scope.
ARs are pricey but most are unbelievably accurate, my circle of shooters tend to go with Savage bull barreled bolt guns in .223 and .22-250 and ARs for varmints and predators and I read about the big money guys shooting all kinds of wildcats in ARs for busting song dogs and over grown short tailed putty cats in this area. I'll just shoot my AR and the single shots cause that is what I like playing with. I also know guys shooting predators out to 100 yds with .17 HMRs with a high success rate and don't see why the .17 HMR wouldn't work on ghogs out to about the same. Shot placement always being critical.
