Hello from Georgia,
It has been mentioned a few times, but I would like to make my case for the 45/70. First of all, it is plenty accurate out to 200 yards and beyond with a little prep and practice. Second, it is very accurate. Third, I do not think any coyote on Earth would ever escape after taking a 405 gr. slug square in the shoulder. And finally, thay are so dang accurate. Perhaps it is a bit much if you are going to save the pelt, but........it does make for an affective round for stopping a big coyote. Sure there are plenty of smaller calibers mentioned, and each would be sufficient, but hey, if you are going to make a hole, it may as well be a B I G one
. One more Handi I think has been overlooked is the .280. With 110 gr ballistic tips, it is an extremely accurate flat shooting round. But I still prefer the .405 45/70. Have a great day.
