I have three 20 P's an AR(don't use it much for hunting preds) a bolt action carbine and a heavy barrel bolt action.
The AR what little I use it isn't a serious coyote rifle. I feed it 34grn Dogtowns and 39gr Speers.
The little carbine thrives on 32gr Nosler HPs, sadly discontinued but have been great on coyotes 200 and under, never tried it farther. I built it to hunt cats and fox but it works fine for coyotes. When my stash of 32s drys up I'm going to give the 35gr Bergers a shot.
The HB rifle lives on a diet of 40gr NBTs, no complaints at all.
I rarely have shots over 200 yards on coyotes, I don't set up for them.
