Chokes

I’ve tried many of the aftermarket chokes but recently I got out my old 1990 32” Beretta 682 sporter and wanted to lighten the barrels a bit so put the original short non extended Mobil chokes in. I was amazed really how well these broke clays and how well they patterned.
Sometimes I think it’s maybe best to stick with what was designed by the manufacturers for the gun - just a thought!

Had my old MK38 fixed opened up and used Brileys, excellent pattern with whatever choke I used, now have Teagues and can’t fault them either. Stick with whatever you’re happy with. Makes life easier!

Can’t rate my Teague’s highly enough and going from fixed choke to there thin wall variation has made no difference I can tell to the balance of the gun. If anything it feels better but that could be my brain trying to justify the spend even to myself

I sold my best mate my wide action original 682 sporter about 20 years ago . It’s still shooting like the day it came out of the box and the Mobil Chokes are lacking nothing . Those guns and the first 682 gold were breathed on by the Competition department at Beretta !

I think the old 682s were one of the best guns Beretta ever made. There was a 30” sporter on Pigeon Watch the other day going for £400 - I couldn’t believe it but I have too many guns already!

I've had a little dabble with teagues in my dt11 just lately but have gone back to the original optima hp chokes. The teagues looked very pretty (the main thing) but went on a sim day and found one had come loose before the end of the day, even when I'd installed them with the teague choke key as tight as I could. With the beretta chokes having notches in them you can just get that extra tightness on them. Never really noticed any difference with any of the chokes performance wise other than looks and weight at the muzzle.

Smear a lot of Rocol Sapphire grease on the thread. They stay where they are then.

I suspect that aftermarket suppliers don't have the exact thread spec for the exact gun whereas Beretta probably do.

Or any other grease

I`ve had guns with Invector and Mobil fitment,12 & 20 bore and used factory ,teague and Muller aftermarket chokes .All performed well but only the factory chokes stayed tight no matter how many shots fired !!! Same with current Zoli gun.
Hth,
Garwood.

I’m not having trouble with my Teague’s but then again my gun was a fixed choke prior to getting re worked by them so maybe it’s a good fit as it’s they’re thread which would agree with @Freddypip regarding his suspicions regarding thread specs

When I had my auto I got into the habit of checking choke and tightening it as I came out the stand/before putting it away as it would work loose every few stands. Don’t get that on my K80 and teagues but I do change chokes during the shoot sometimes and as they stick out the end I do twist them with my fingers to make sure they’re not loose every few stands.

100% do the same thing in fact when I first got my K80 before it was multi choked I spent weeks trying to tighten chokes that weren’t there as I had been doing it for so long before. I’d be walking between stands and my hand would just go to give the extended choke a little turn to make sure it was still tight and there would be nothing there . But there is now

I have enough to think about when I am shooting without having to faff around with my chokes too ! I stopped using Teague chokes years ago, because they kept coming loose in my Beretta auto, swapping them for Briley. I now use solely Briley in all of my multi choke guns. I put a drop of Lucas gun oil on each choke, before fitting it into the gun. I only remove and clean (wipe with kitchen towel, reoil and refit) after every 6/8 outings, unless the gun gets wet, and I have never had a stuck choke. This method has served me well for over 20 years.
I do use a gunslip, not wear my gun like a bloomin scarf So checking the chokes is less convenient.

It is interesting that the main issues would appear to be with fitting aftermarket chokes in manufacturers threads although not much data to go on here. Besides guns with chokes from the people who made said gun the only other “none standard” chokes I have had is some Muller Chokes for a bennelli 828u I had and they where beautiful and never came loose. I’m afraid I am very much of the over the shoulder brigade of gun moving around. Admittedly much to the dismay of a lot of people older and wiser than me. I have tried the bag between stands but it really isn’t for me. Although the minute a chunk of clay bounces off my re finished stock I will more than likely feel differently . But until then I will continue to tighten as I go

The secret is buying a gunslip that is 'free standing'. Stick it in the gunrack, unzip, remove gun. The slip stays upright until you return the gun to it, zip closed, and carry on. I hate to see people remove a closed gun from a slip, then wave it around whilst looking for somewhere to stick it. I have offered some ideas on many occasions. I just object to having my ear belted by a gunstock, that is my only gripe against the over the shoulder brigade.

I can only but agree with your comments regarding people with guns on there shoulder being less than aware of there surroundings. Having said that it’s not an issue I have as I’m very much of the Digweed persuasion regarding stature so im fairly aware of my surroundings at all times. Like a bat but jolly I also love the fact you have named the group the shoulder brigade. We call the other fraternity Happy Baggers as they always seem to be ever so slightly happy every time they use the bag

So you think they can manufacturer a hi performance item machined to thousands of an inch but can't measure a thread

I'm sure they can measure the thread - they might even know how to measure all of the info required to replicate it - pitch, root, crest & all of the diameters etc. I suspect however that Beretta have changed their (exact) specs over the 20 years the Mobil choke system was used - god knows how many guns over that period. An aftermarket choke has to fit all guns with that system so if they measure various guns and end up with some variance (particularly in root & crest) they have to compromise to ensure the aftermarket choke will fit everything. So to repeat - "I suspect that aftermarket suppliers don't have the exact thread spec for the exact gun whereas Beretta probably do."

I do not think the make of the choke makes any significant difference to the way it performs. I have always used Briley chokes because I am more than happy with the way they stay put in my gun during use. Would you put up with having to stop and check your cars wheel nuts every couple of miles ?

Westley - Agree with you there.

It's interesting that Blaser went to Briley for their chokes for the F3/F16 and there's nothing particularly unusual about them. They are about the same length as the old Beretta Mobil system. Of course they do have coloured bands.
