Use to shoot a side match at 100+ yards with all 4 of my 45 Colt Henry Rifles. I had great success keeping groups inside a Pie Plate at 100 yards. Off a shot bag rest. Not off-hand. Not since my eyes went south.
Like others, I found accuracy went away after 10 - 15 rounds. Still within "minute of Man" but not in the Pie Plate any more. Had to run a swab thru the bore about every 11 rounds.
Oh, forgot, my 16 inch barrel Trapper. Not so much. Meh. Deadly at 50 though.
