Also - Richard, what is the choke run-out length on those bores? That might be interesting as well..?? John
I finally measured the choke runs on my GHE12. The right bbl is no help... it has about .3" of choke that actually opens a few thounsands. A mini blunderbuss this bbl and likely honed at some point??...certainly not by a modern gunsmith though as the choke portion has a mirror polish, which seems a totally lost art as far as I can tell. woodcock and grouse in tight cover beware this puppy! The left barrel has about 2.5" of choke that constricts .015".
I think that the next time I want chokes opened I'm just going to dig out the brake cylinder hone I've used on my '65 GMC and '66 Bronco, dip it in butter and beach sand and just do it myself. I'd get better results than what the supposed "pros" have done for me... Did someone change the definitely of "polish" in Websters while I was napping or what??
