When I shot that round in a blackhawk conversion, it was fine for recoil and I would not hesitate to drop a deer with it, if it fails to open, then fine I am also happy with a cast that does not expand. If it expands on a whitetail, after going into the vitals it cannot be all bad. That did not sound like a bullet failure that would cost you your deer with good placement, and that is the requirement regardless. the jacket separated by the fourth gallon ; that is a lot of lung and heart destruction and a likely exit hole.. I think it would be fine .. but there are more knowlegeable hunters here than me.
Just my two cents, but I would use that round in my blackhawk for deer in a minute... have not yet though...
My opinion on this is free. lol
