Have you tried anything lighter than 400gr.?
300gr at 1600 fps. would work just fine even on the biggest bucks.
Rock on, but extra recoil stopped being fun a few years ago.
Don't get me wrong, I applaud you for your workaround to maintain legal and use a firearm you already owned.
I would have done this if I had a 45-70.
Since I didn't, the Ruger American Ranch in 450 Bushmaster was a cheap price for a rifle legal in the Zone I have hunting property.
