Jug Choke Info

loud-n-boomer · May 15, 2023

I am building a 10-bore New England fowler and am going to jug choke the barrel. My question is what angle/taper should I cut on the breech and muzzle ends of the jugged section? I am thinking that it should taper at about 0.030" per linear inch of barrel, but that is purely a guess.

Let someone who knows jug chokes do your barrel.
If done right, a jug choke works very well. But can ruin a barrel if done wrong.

Since I am a reasonably capable machinist and I own a Monarch 10EE toolroom lathe, I would like to do it myself if I can get information on the appropriate geometry to use.

Well, most of us here are not machinists, so the specifics evade us. That’s why I suggested letting someone els do it.
Again, I’d suggest contacting someone who knows how,
There are several recommendations on those who do jug choking.
Lowell Tennyson, Bobby Hoyt, many more.

Good luck, I have asked about jug chokes and got no real answers. Must be top secret.

There is a book somewhere that gives the specs. I have no idea which book as I pay other people to do those sorts of things. I'm no machinist!

I did a search just now on my I phone. Typed in Jug Choke. There was a post from years back on American Longrifles forum. Looked like maybe the info you seek may be somewhere in those series of posts. I’m not a machinist so I sent mine out for the work. I respect your wanting to do it yourself. Hope this leads you in the right direction.

Thanks to all for the leads. Once I have some answers I will repost them here in the hopes that it will help someone else.
