Rebore - Hiwall55 - 03-26-2017

I have a .40 barrel for a CPA and would like it bored and re-rifled to a .44(438-446) with a 17 twist. John Taylor and JES don't have the tooling. Any body else?

Have you considered selling or keeping the .40 Cal barrel and ordering a Green Mountain Barrel?
I have one of those 17 twist Green Mountain Barrels in 44 Maynard (44-70) that is amazingly accurate.

The .44-70 Maynard would make a fine caliber, it is for my future. I checked on this, to have CPA fit a barrel for your action it would run about $700. with them supplying the barrel.
What is the barrel and twist of the .40 caliber you want to rebore? I might be interested in the barrel.

Have you checked with Norm Turner that advertises in the BPCR news?

Norm Johnson in ND does reboring conversions. He has an ad in BPCNews.


RE: Rebore - Hiwall55 - 03-26-2017

The barrel is a green mountain #4 Winchester taper, 16 twist, 30 inches long and D+T on 17 inch centers for an MVA 28 inch scope. Chambered for .405 Hornaday brass by CPA to be a 2.5 40/70 SS.
I built a 1885 with a badger barrel using Captech brass and I prefer to shoot it so I leave the 38/56 barrel on this CPA rifle.
Thanks for the leads on the rebore
