choke backing out

[davebo]

Hi

I have been shooting my new beretta 391 urika and just throwing the trap load through it. but I have noticed that the choke keeps backing out. Anyone else have this problem or a fix, other than checking if the choke is in between clays (empty of course).

Or is it a case of the barrel heating up and causing a difference in expansion between the barrel and SS choke?

Thanks

Firm finger tight with a little choke tube lube, they should stay put.

I'm in the habit of checking in between stations ... have never found it
neccessary to check from shot to shot.

Most likely due to barrel heating and expansion, I have the same issue with my 11-87 with extended skeet choke. I use a little synthetic choke tube grease on it and it keeps it in tight. Just fills the gap a little. With the extended one its easy to check every couple stations anyway.

The choke tube grease ( silver never-sieze works well ) adds strength and allows you to tighten it more firmly.... and then it is just a matter of checking it...

Can't hurt to put a very small spot of loctite, the blue stuff on there.

thought about that ....I guess the red stuff is out of the question...

Loctite? You guys are amaturers. JBWELD!!!

Just kidding.

My father in law uses automotive anti-seize and I use muzzle loader nipple grease.

NO Loc-tite & No JB, never !

Stay away from loctite there......use the grease suggested above....unless you want more trouble...

A very small spot of blue loctite ain't gonna cause problems. Now very small is very small, not so it runs all the way round

A small chunk of "Double Bubble" chewing gum would work too !

Birchwood Casey Choke Tube Lube works well for me.

This has always been a problem with Beretta semi-autos and more so with the Optima chokes. I use Briley choke tube grease and it seems to hold them in. I also dumped the little hook choke tube wrench and got a Carlson's screw in choke wrench which seats the tubes in a little firmer.
