Builder, all my choke tube guns (both of them) get some gas stain and I've been shooting them for more than 20 years in competition and casual shooting. It is impossible to seal at the back end without hand fitting and some gas stain is part of the deal and harmless. My Beretta and "Briley for Beretta" tubes have been shot tens of thousands of rounds trouble free and are usually a little dirty when removed. The Lovely Linda's Krieghoff has Briley installed screw ins and it's the same situation.

Thanks. I feel better now. I guess I won't have to sell it before it blows out.

Best,
Milt

I know a fella that dropped an Briley choke tube. It looked fine and fit the threads perfectly. However it was just wenough out of round that the next time he shot it the barrel bulged at the choke. He replaced the tube and shot the gun with a bulged barrel for years and years. Then one day.....

He was on a chukar hunt and he shot a double (his first). One of the birds was torn to shreds, then he noticed that his choke tube was GONE. He thinks the tube hit the bird, and I think he is right about that. (Eightbore, you know the guy)

Now that's centering your pattern!

Wuz shooting SC with a guy once who changed his choke, but didn't tighten. Choke was just inserted, not torqued at all... we walked out 25 yards or so, and picked it right up! No damage... other than to pride. B391, Angle Port.

A wrap or two of teflon tape on the threads seems to keep the optima choke from backing out of my 391 SC. Teflon tape used on pipe threads is cheap and easy to remove while cleaning the barrel.

Excellent idea. Thanks! Lots of it around. Probably eliminate rust problems noted above.

I have often noticed the tubes not tight on one or another of my guns while hunting, and I could see where there had been obvious gas leakage. I was thinking about using some Loctite on the threads, but concluded it must not be a big deal beacause nothing had ever been harmed, and I shoot the rompingest stompingest loads available when shooting at geese or pass shooting big ducks. I have even tightened the same tube more than once on a hunt using a quarter. Maybe I will use some Loctite - cheaper than a replacement tube.

I would not use Loctite since the thread area is very large and the adhesion would be pretty substantial regardless of which type of Loctite. You might try some plumber's teflon putty or the tape.
