Indeed, a very interesting discussion! For more then a dozen years now, I have been using a 1895 XLR. I have used nothing but soft cast,(95% lead, 3% antimony, 2% tin) gced bullets in this gun. I have shot deer at ranges well over 200 yds., bear at distances over 150 yds., every animal has been a 1 shot kill, using a Kieth design, Rapine mold bullet (drops 333gr.). Every shot has been a clear thru shot! I keep wishing that I'd have at least one bullet, not go thru, so I can see how it flattens. This year, I'm going to use a new bullet, from the NOE HP mold, that drops 324 gr., in hopes that maybe I will find a bullet in one of my carcasses, just so I can see how it flattens!
A very good thing about the .45-70, no blood shot meat! Ya can eat right up to the hole!
