Hello, Nobade, Thanks for reply..I should have been more clear..I was thinking of rimfire. Your comment about High-power Silhouette & irons brought back memories..Back in 1980 I attended a High-power Silhouette match..Only rifle I had that was accurate enough was an 1896 .30-40 Krag carbine. At home range, at 200 yds. I could use the little flip-up peep on rear..showed up real nice on the paper targets..once at match however, I couldn't see a thing thru that tiny hole! Had to shoot match with the open sights. Got a few chickens, did ok on pigs, turkeys were left & right..even off sight in bench!, I remember I hit 5 rams, but only 4 went down..almost too hard to be fun with those open sights! I do remember the smoke from that linseed oil soaked stock when I was through!
