Howdy!

Do any local gunsmiths have a .38-40 chamber reamer?

I have an Old Vaquero with the dual cylinder .38-40 & .40 S&W set-up. The gun is great, but the chambers on the .38-40 are a bit tight, allowing Winchester factor .38-40 to fit fine, but Black Hills Cowboy Loads need a few thousandths more shoulder room. Both rounds chamber fine in my 1908 Colt New Service.

Thanks!
