Colerain barrel

[MI MAN]

Does anyone have experience with a 50 cal 36" Colerain 1/56 twist barrel I am going to put together a kit with this type of barrel. Specifically interested in loading such as powder loads, patching, RB etc

No,

Mine is 38" 1:56 and swamped, and .54 with round bottom rifling. I use a .530 ball and a .015 patch over top of 70 grains of 3Fg.

You did a great job on your rifle. I ordered this same barrel on the TOW Ohio percussion rifle kit I just ordered.

Thank you. I have just finished fitting and sighting in a .40 Colerain barrel to this same gun and I'm pretty happy with the results. 50 to 60 grains 3F Swiss shoots great - turkey head accuracy at 50 yards. For what its worth, the Colerains seem to me a bit tighter in bore diameter. I had to go down to a .012" patch on this one.

Tom, I’ve noticed the same in their smoothbore barrels as well.

My 16 gauge Colerain mics at .653.

Yep, I shoot 55grs. with .018 patching. I Use TOTW mink oil for a lube you can use other lubes. Basically I can shoot a group the size of a half dollar at 50yds.
You need a thicker patch with the radius groove rifling.

I have a Colerain .50 caliber barrel sitting on the workbench. I had it cut down to 32 inches. Yes, I too am wondering about how well it will shoot prb. It's my first Colerain barrel. Some of my other front stuffers all sport Green Mountain barrels but GM was out of stock when I ordered the new rifle parts. So I figured "what the heck", let's give it a whirl. Now, if I can get the back ordered parts, I will be able to finish.

I think you Guys will love your barrels.

I’ve owned both GM & Colerain barrels, currently I own a 1 in 56” twist .54 cal Colerain that’s 42” long.

The gun shoots better than I do.
My gun has radius bottom rifiling, I shoot 15ths pillow ticking patch a .530 ball & 70 grns of fffg.
