I have an unmolested 42 made in 1954, with a 28" Full choke barrel. Choke measures .395" at the muzzle using a precision inside mike. My bore gauge will not adjust small enough for 410 barrels, but assuming a .410" diameter bore, that would make 15 points of constriction for Full. Silvers


I AM SILVERS, NOT SLIVER = two different members. I'm in the northeast, the other member is in MT.
