I shoot off of a bench, I shoot prone, and I shoot off of a PSR top with revolvers.
Two of my revolvers are sub MOA at 100 yards and sometimes further. They are not factory revolvers. They have scopes.
I have been able to shoot sub-moa at 100 yards off of the bench and off of Bog-Gear with 5 different revolvers (Three 357 Mag's, 41 Mag, and a 44 mag)-Two of them are mine, and the other three are not.
I can't do this all of the time, especially beyond 100 yards.
Plus, I don't shoot for groups at 100 yards once my load is developed.
