Since the modern conversion cylinder has throated chambers, to use the .44 Colt Original you would have to bore out the troats to .451" or .452" -- which would then render it unusable in a firearm with a modern .44 caliber barrel.

I'm considering getting a Howell conversion cylinder for my Pietta 1858 Remington "Navy" - don't want to steal this thread but do have a question that others may wonder about as well. On the Howell conversion for the Remy Navy - cylinder would be in 38 Special - are the chambers "straight bored" - i.e. with no throats?

You are shoving a .358 lead bullet down a bore that is .374 ish- so I would be using a 145ish grain hollow base round nose lead bullet. I'm just wondering if they are straight bored or throated so you can use a "heeled bullet" that is .375 on the business end but that can be seated in a 38 Colt Long casing (Starline). In reading he description of them on Taylors, I don't see anything as to how the chambers are bored (cylinders for 38 Colt Long/38 Special)?

Thanks.

bedbugbilly,

Howell makes the same recommendation that Kirst makes - use hollow base bullets or have your barrel lined to .357.

I'd bet the chambers are straight bored but you could give them a call and ask.

COLT 1860 Army cartridge conversion snub nosed. Came out nice. Functions flawlessly.
