I’ve killed a good couple handfuls of whitetail does with my Montana. Longest one this past season was a bit over 200. Handload the Speer 70gr Semi Spitzer. Bullet performance was the same as all the others I have killed. All exited and showed signs of good expansion. All my shots have been broadside behind the shoulder. In my experience they tend to run a bit further than with the larger calibers and the blood trails generally aren’t as easy to follow. But I still like it. Shot placement matters more. Also killed my biggest pig with it, but that was through the ears at about 30 yards.
