27 years ago, I could and did shoot groups like that. 50 yd off hand 50 4 X signed by the range officer. 49 4 X at 100 yds
shot from prone. I used both .45 and .54 flintlock rifles. At 61 years old, I can't shoot like that any more, but once in a while the stars line up and a 50 makes me smile !!! There were many matches where a 49 wouldn't place in the top 3
More than once we made the centre fire shooters take notice on trips to the range. If the wind cooperates, these rifles can shoot impressive scores. I'm never surprised when the average shooter today , used to scopes and cartridge rifles , doesn't believe the scores /targets turned in by muzzleloaders shooting round balls.
It helps that we actually do a lot of shooting i.e. practice , which is not something the instant gratification boys are familiar with. "Smart" scopes, i.e. he who spends the most $ , wins is something I see more and more of. Nothing p**s off a .338 Lapua guy more than showing up with a 45-100 Sharps and shooting 9's and 10's at 1000 yards.
