I simply get tired of the amount of misinformation presented here by those who have never, nor will ever do what they are presenting as fact...
I'd still like to see any reamer that could be adjusted from the muzzle end of a shotgun barrel while in the bore.
Joe, Google BORING BAR, Lathe....
Then try to find out what an expandable reamer looks like...
For that matter, you might try to find out what a jug choke looks like.
I quit.
I thought I had a pretty good idea of what jug choking looked like...correct me if I'm wrong.
Its a honed section a few inches behind the muzzle that's generally a few inches long that's a larger diameter than the bore behind it and the muzzle end in front of it ?
If I am close to being correct in my layman's description how do you propose this was done without some type of expandable reamer ?
