Achieving 1MOA at 100yds using IMR4198 out of a Marlin Trapper, which has a 16.1" barrel. I never imagined I'd achieve this kind of accuracy with a 45-70, let alone one with a shorter barrel. I've used the 190 grain bullets in my 300 blackout on deer and they have dropped the deer within 10 yards, if not right in their tracks. I can only imagine what these will do for deer and bear.
