I just ordered my .62 smoothbore barrel for my renegade from GM Barrel Co. Great deal!!! Does anyone know a good gunsmith to install choke tubes ? Thanks, John
John, have you finalized what it is you're planning to hunt with it and are you sure you want to have it set up for choke tubes?
Reason I ask is...and this assumes you got a muzzleloader smoothbore barrel to use it like a traditional smoothbore barrel would have been used is that "constrictive chokes" can interfere with the use of traditional wads and cards in a smoothbore.
For example, if you were to use Circle Fly's prelubed cushion wads, they are made "bore size"...but if you force them through a "constrictive choke" like a screw in choke, they will get compressed smaller, then won't seal tightly inside the full size bore after they get pushed through the smaller diameter screw in choke.
I've heard about three attempts to alleviate the wad compression problem of screw in chokes:
>>>One attempt is to use Oxyoke pre-lubed Wonderwads with can be slightly bent (bowed) and pushed through the choke, and then you have to turn them flat to seat them down;
>>>Another attempt is to use several over shot cards bowing them through the choke the same way then getting them all turned flat behind the choke to seat them down...you lose the benefit of lube just using cards instead of Circle Fly or Oxyoke wads.
>>>And another attempt is to unscrew the screw-in choke every time to load the smoothbore then screw the choke back in.
None of these approaches serve the shooter very well if you're intention is to use it for something like trap, skeet, doves, quail, etc where there's an expectation of lots of shots, possibly in a short amount of time. If your only interest is to use it for a one shot situation like Turkey hunting, then those approaches would probably work even if it was aggravating to do all that.
By contrast, a "Jug Choke" works by creating an expansion chamber that is actually slightly larger than the cylinder bore so no wad compression occurs and you just load powder, wad, shot, OS card, and take your next shot. You tell the gunsmith what choke you want created...(ie: IC, Mod, Full)...based on the majority of what you're planning to use the smoothbore barrel for...and he'll hone out the expansion chamber the amount required (.015"/.020"/.025", etc)...to create that degree of choke.
