The Halls leak no more than a percussion revolver ... albeit it is a rifle caliber (52-cal, firing a 0.525" ball) where the service loads were 82 or 100-grains!

Other than that ... a piece of cake!


All of my MZL'drs will shoot into ONE ragged hole ALL day long ... it's just those darn 2nd & 3rd+ shots that tend to open up my groups!
