.45 Caliber Lyman GPR

[DanChamberlain]

Received my relined barrel from Bobby Hoyt yesterday. It's nearly impossible to see where the liner mates with the original steel. I now have a Lyman GPR that I can approximate .45-70 performance with. I'm a dyed in the wool .45-70 fan and always wanted a traditional muzzleloader that I could use with the same conicals I use for my BPCRs. This gun will not be used with the super heavy bullets, but rather a 345 grain bullet I like to use in my Marlin and Contender. The Lyman breech plug isn't meant for 120 grains of powder and a 500 grain bullet! So, it's 70 to 80 grains and be happy with that. I'm thinking a whole lot of large critters fell to loads like that.

Sounds like a cool project Dan. And a good way to save a worn barrel. If you don't mind me asking, about how much did the liner job cost?

I sent him the .54 caliber GPR barrel and he did the work for $160 shipping included.

He is supposedly the "Go-To" guy for muzzleloading barrel work. He's difficult to get a hold of, but he's a gentleman and patient with novices like me.

For better understanding to a german ML fellow. relineing means to make a barrel in the barrel in a smaller cal, so as in your case an old .54 was relined (made smaller) in a .45. In Germany we call this "Futterlauf".

What Robert Hoyt did, was to bore out the .54 caliber hole, and insert a .458 caliber liner into the bored out tube. Once in place, the seam is nearly invisible.

By the way, I spent 4 years in Wiesbaden near the Taunus region. I was a member of the USAF Kriminal Polizei OSI. Fond memories.
