djgeoff Posted August 2, 2011 Report Share Posted August 2, 2011 i have noticed that after a good session approx 100 carts 32 6's the choke in my Beretta urika auto may have worked loose. is this a common thing for chokes to become loose? i do use proper tool to tighten but i do not want to over tighten and then later find i cannot remove it. i have seen other shooters with stuck chokes and it can be a pain. So for now every now and again i give coke a quite check with finger ( gun not loaded of course) regards geoff Quote Link to comment Share on other sites More sharing options...
BlaserF3 Posted August 2, 2011 Report Share Posted August 2, 2011 I have experienced this also but I use a Teague tapered key on mine and give it a good tweak and now it doesn't come loose. One good thing about Optima chokes is if they do become stuck, you can use a pair of mole grips to slacken it off :o Quote Link to comment Share on other sites More sharing options...

Gordon R Posted August 2, 2011 Report Share Posted August 2, 2011 Another vote for the Teague tapered key. I use one and have never had a loose choke since. I have seen a number of people hand tightening their Optima chokes between stands. In my book, it's potentially too late when they are already loose.

welshwarrior Posted August 2, 2011 Report Share Posted August 2, 2011 I nip mine up quite tight on the 682 with the plastic key before each outing then remove them after each round I have a strong metal ket for if they are a bit to tight. I always put copper grease on the treads. When I first got the gun the choke sometimes came loose they don't now. Quote Link to comment Share on other sites More sharing options...
Guest cookoff013 Posted August 2, 2011 Report Share Posted August 2, 2011 i use any grease for the threads.. although they might still need tightening after 200 shells or so. Quote Link to comment Share on other sites More sharing options...
djgeoff Posted August 2, 2011 Author Report Share Posted August 2, 2011 thanks for the advise chaps, i have always smeared thread with gun oil when cleaning but it seems grease i should have been using so i will try that. but as one chap said he still had to tighten after 200 shells so i presume they do work loose, i think i will just keep a check on choke now and again to be on safe side. ta very much regards geoff Quote Link to comment Share on other sites More sharing options...
Guest cookoff013 Posted August 3, 2011 Report Share Posted August 3, 2011 the problem with oil, is it evaporates quickly when the gun is hot, grease doesnt, dont use too much as when the gun gets hot, the grease will naturally try and migrate out of the thread. just get some stuff called gungrease or a lithium-moly blend. you can get away with replacing it every 4 months or so, and it still will unscrew nicely after that. i had an old chap who, i offerd to clean his barrels and chokes. i almost couldnt get them off. they were seriously carbonated. the build up took ages to soak away. he used oil, and changed his choke about a year ago !

4eyes Posted August 3, 2011 Report Share Posted August 3, 2011 Cheers folks, I've been watching this thread too as the chokes in my B425 work loose after 70 or so. I have extended chokes in them so I've just got in the habit of checking them after each stand and nipping them up if required. Never thought to use grease (copper slip) rather than oil.

coyotemaster Posted August 4, 2011 Report Share Posted August 4, 2011 If ever need be there is a product called KROIL that will penetrate along side the tube down to the threads works like charm on stuck or rusted in tubes. Quote Link to comment Share on other sites More sharing options...
HDAV Posted August 4, 2011 Report Share Posted August 4, 2011 Grease is much better on all metal to metal contacts, oil will drip and run grease doesn't better on ejectors hinge points etc Quote Link to comment Share on other sites More sharing options...
