You just need to put “reverse direction” shock collars like on my yeller lab’s underground fences Coach…...keep ‘em all out but always lets (snakes) ‘em go the other way.
Keep those pics coming, Coach. Nothing better than pics. Of dead copperheads!
Felt recoil is always an individual thing. I shoot the 3” loads in my Bond Texas Defender, 2&1/2” barrel and really isn’t bad, especially when shooting to kill.
I don’t go out and punch paper all day with it. Nor with my 45-70, .270, 30-06, 309JDJ, etc., etc. But I never feel the shot launched to kill.
