Boring CVA

[riarcher]

Been thinking about this for awhile.
Have an old (30+yrs.) CVA Kit gun that I made way back when. One of them .45 cal 2 piece stocked Kentucky rifles.
Been thinking of having the "Junkar" barrel drilled out and honed to a .50 Cal smooth bore.
How hair brained of an idea would this be,,, and who would do it?
I have concerns about the idea of round balls after the drilling as the flats are .880, dovetail on the rear sight sets in about .110, and if I went to .505/.510 bore I'd only have about .125 of barrel left under the dovetail.
To me, this sounds a bit scary, but then I think it's only about .025 change in wall thickness, and with the rifling gone I couldbe reducing presure significantly from what I'm using now (70 gr 3Fg w/.445 RB).
Interestingly, I see that Circle Fly makes all the shotgun style wads for .510 :: So perhaps a .50 cal shotgun isn't all as unusual as I thought? :hmm:
Thinking 65 gr. 3F and 3/4 oz. shot as a starting point?
Any comments/ideas? :youcrazy:

 

and having a .50 cal through a 7/8" tube would be more dangerous than having a .50 hole through a 13/16" tube?

I have 2 .50 barrels that are 7/8" from the factory. I have one .50 that is 13/16" and a .45 on a 3/4" tube.

I also have a .625 smoothbore that starts at 1" across the flats and gets thinner from there. It has a dovetail cut in the flat section too, along with lugs for the pins.

as long as you do not try to burn 150 grain charges with 350 grain conicals or double balls you should be allright.

I have a 7/8" 45 cal. CVA barrel rebored to .625, about 20-25 yrs. ago, so far no problems.

I would, what I want to do is take a .32 caliber flint rifle and have the rifling drilled out to post-produce a .33 smoothbore, for squirrels and bunnies...

As Ghost stated, keep the powder charges down and be careful around the dove-tail cuts...

Good advise from Ghost...

AWSOME!!!! :thumbsup:
And who does this stuff? Realisticly priced of course.

Contact Ed Rayl 304-364-8269 or Roy Hoyts 717-642-6696 both do reboring and cut rifling. I imagin they could bore one smooth too. Ed Rayl charges about $100.00 to rebore and rifle a barrel. Don't know about the cost for smooth.
