I don't know what factory rounds do in my 45-70, but I shoot a 300gr partition at 2050fps and 2" high at 100, I zero at 140yards, and at 200 yards, I am 7" low and still have over 1200ft-lbs of energy at 200. If a person can't ultilize those bullistics to take deer out to 200 yards, they probably shouldn't be taking deer under 100.

I have taken a few deer with it. Excellent performance. But considering changing bullets to 300gr sierra. The partition would be great for moose, but I went lengthways in a deer and still didn't find the bullet, so I wonder if its expanding much.
