I am very picky with accuracy. I always have been way back to my IPSC days.
I can put all 6 rounds of 45lc into the size of a 50 cent piece at 10 yards with a Governor. I can stack bullets with a 6" S&W 629 44mag at 20 yards. Same goes with my 1911. My Sig P229 40s&w Dark Elite and Walther PPQ 9mm I can do a 1.5" group at 20yards. My rule of thumb is,...If I can't reliably do a head shot at 20 yards, I don't carry it. I practice out past 100yards with my 44mag a lot.
I practice for shots like this....after that, 20yards is a chip shot.
