Understanding breech plugs
« on: February 10, 2019, 02:00:59 AM »
If I want to use the a weight 44” .36 American heritage barrel with a lollipop breech plug,  how do you make it work other than fabricating one?  TOTW has lollipop breech plugs for a 13/16 and a 7/8 barrel with the correct threads.  The breech for the a weight barrel is .960.

Muzzleloaders Building supply has them for 1" Breech barrels, should be easy to take .020" inch off (top/bottom).

Meant to add that they are fairly easy to make using the fitted flared plugs if you can weld or have access to someone that can.

 Change the breech threads to 5/8 18. Use a plug that fits the profile.

If it were me, I’d get a machined, long tang breechplug and file out my own. It really doesn’t take that long. I had a bad experience trying to fit one of those cast lollipop tangs recently.  The threads were pretty iffy, and required extensive filing of the actual threads to get it to breech up. I didn’t like it, even after the plug was properly seated, and wound up scrapping it and making my own.

Just my experience, YMMV.

I've used that plug, and it was ok.  Maybe talk to a Jim a Kibler.  See if he'll sell you one of his new cnc ones.  Bet they are LOTS better.

Does the Kibler SMR barrel have a 1" breech?  I could be wrong, but I thought it only was available in smaller sizes (.45 cal max) similar to the "A" weight the OP was looking at.

If you can find a 1" lollipop casting, you will have to do so much file work on it anyway, it will kind of defeat the benefit of the CNC machining anyway.  Although you probably wouldn't have to touch the drafted sides which would save a little work.
