I know it's been a while but I finally got to the range and tried those Buffalo Bore .45 Colt 325 gr/1325fps rounds. Well in short, I ain't gonna do that again till I get a recoil pad!!! Those rounds are pretty heavy in this little 20" barrel Winchester. I was honestly amazed at the recoil. I think I'll save them for something much larger and better tasting than a piece of paper.
Well, I said I'd post the results and there they are. I have no idea how accurate the round is, as I only shot 3 of them. They were just too much with no recoil pad... OK go ahead and call me a wimp.. I deserve it....
