My 1922 version with a choke diameter shot 68% with 1 1/4 oz #7.5 shot at 1150 fps the day it left the factory. With contemporary loads of 1 1/4 oz #7.5 shot at 1250 it patterned 72% at 40 yards.
LC seemed to do a pretty good job of building their chokes to match expectations of a standard full choke.
