Looking for personal experience with these 2 bullets in 20 cal on coyotes. Not interested in any other bullet since these are the 2 i have to work with. Will be with a 20 practical. My opinion would be 40 would have the advantage for knock down but ive been wrong before. I shot it for the first time yesterday and will still be playing with loads with both bullets to see whats better on paper. But if one is better than the other in performance ill spend more time on that bullet. Thanks for inputs.
