I've only used mine on shots that were under 100 yards, but it has worked great. My rifle is a Marlin 336 that I've had since 1967. I've killed 6 or 7 deer and a couple of hogs with it. The bullets penetrated the deer completely and left good blood trails that were short. As with any cartridge shot placement is important, but the 44 Magnum from a rifle works very well.
