I would give it one more try since your a hand loader....try Cutting Edge Bullets get 100gr, Edge Flat Base might be surprised I've shot a lot of game using that bullet and in several guns that didn't shoot very good it was a great improvement....
The wife will like it also in the light weight Kimber it is very pleasant to shoot....most animals will be ....DRT....
I shoot the CEB 100gr. Flat Base Raptor in my Kimber it went from a 2" rifle to just over 1"....sure there not cheep but really how many times do you shoot a big game rifle....
