500 hundred grains? you must be shooting heavy cast in the Marlin 45/70 with the cut rifling...but god...500 grains? What rifle are you shooting?
The first time I took out the Springfield 45 ACP pistol I pointed it at a pile of trash in the Southern Calif foothills and the slug hit the pile and a trash can lid flew into air. It flew. I thought, - weight and modest velocity. All my 44, 45 Colt warm, and 41 mag would have zipped through the pile. Maybe several peices of junk displaced.
Then one day I took my new Marlin SS 45/70 with the micro groove into the Ca fields and shot at a log. The log jerked and moved around.
There is a place for big, large face, heavy and modest velocity. I had a lot of fun.
