I've read on this BB that barrel through-lumps are an indication of lesser quality guns. I wonder if that's really true. It seems that a lot of work is required to have them fit cleanly through the action bottom.Additionally, what is their purpose. Do they add strength to the barrel/action joint?

I've read on this BB that barrel through-lumps are an indication of lesser quality guns. I don't know who would make a dumb a$$ statement like that. Both LC Smith and Uncle Dan Lefever designed pretty damn good guns which have barrel lumps that extend through the receiver. |  |  |

I agree, dumb statement.  Same has been said about guns that are not stocked to the fences. As to strength, not really, hidden lumps are just as strong, just that you can't see them is all.
 Best!

Fair question. The better-finished guns from England usually didn't have through-lumps, and they charged more for them accordingly. |  |  |

Exactly my point. Is it just a matter of fashion or is there some reason that the top tier of British makers don't use them on their highest grade guns.

The London Best Rigby rising bite (vertical bolt) has "through-lumps." |  |  |

. . . and Purdey never built a gun with through lumps.

And the MacNaughton round action has through lumps, but the Dickson does not.  When did the through lump become less than a "best"?

I am of the opinion that a well fitted through lump will reduce the forward stress on the hinge pin. Same principle as a well fitted lump joined on the circle. There were many great makers who used the through lump, such as Lindner.

Actually, the Dickson does have through lumps, you just don't see them because the trigger plate covers them. Because of the space required for the cocking slide, I think the lumps would be a bit stumpy if they weren't through. There's no space to spare in a Dickson. That's why they're so much prettier than a London gun.... |  |  |
