I took my Marlin to the range today to crony the very accurate load of a 405 gas check Cast Performance bullet over 55 grains of Varget. The average velocity of the load was 1,821fps and the bullet drop (average) from 100 yards to 200 yards was 16.75".
Well, my first 2 shots were barrel fouling shots at 100 yards and each shot 2" low. But then I shot 3 consecutive rounds that cloverleafed at 100 yards! This is with a peep sight on the Marlin.
These guns are more accurate than I am.
