I have a Forehand and Wadsworth all matching with the 5 shot cylinder where chambers measure .46 at the breech, .453 at the mouth and 1.3" long.
The barrel of that bulldog is .408 with 5 groves.
Chamber wall is 0.055" at the mouth. There really isn't enough material there for reaming the chambers for a liner, and I don't want to both re-chamber and line the perfect good barrel.
One option for shooting this gun is to make ammo out of 44 mag cases shortened and necked down with 41 cal bullet. Perhaps running a 44 mag case 1/2" into a 41 cal sizing die then using a 44 mag bullet seating die would do the trick.
Another option is to make cases out of 303 brit and keep wall thickness.
But I also thought of buying this product: http://aircraftproducts.wicksaircraf...1016|3103|3081
expanding it slightly over a mandrel to make the chamber liners, soldering them in then grinding the chamber liners to the diameter of 41 long colt dimensions. That can be done with only a wooden dowel wrapped in sandpaper and won't require a chamber reamer I think.
Or one of these can be used:
1/2" OD 0.444 ID http://aircraftproducts.wicksaircraf...1016|3103|3081
1/2" OD 0.430 ID http://aircraftproducts.wicksaircraf...1016|3103|3081
In the 2nd case I would leave ID alone and grind OD to fit in the chamber, in the 3d case grind both. Is .444 too large a chamber for 41 LC?
What would you do? Make custom ammo, or line the chambers for 41 long Colt?
