widgeon man Posted April 19, 2015 Report Share Posted April 19, 2015 If you notice it is the beretta hp new choke........... Lots of problems! Poor with steel shot especially, mainly chikes swelling/tight............. First I have heard of splitting though. Beretta should have stuck with the excellent optima system imho Quote Link to comment Share on other sites More sharing options...
Westward Posted April 19, 2015 Report Share Posted April 19, 2015 From the carbon build up on the skirt this choke clearly failed through neglecting to tighten it. HP chokes normally have a very good seal against gas blow by if properly installed. The supplied choke key is there for a reason. Quote Link to comment Share on other sites More sharing options...
shaun4860 Posted April 19, 2015 Report Share Posted April 19, 2015 Can I just add that I have 2 Muller U1's (Inv +) Had them for a couple of years now and no problem whatsoever with them, Looking at the Beretta one, try contacting Beretta on a Sunday and getting a response straight away, Give Nick a chance to put it right Quote Link to comment Share on other sites More sharing options...
Old farrier Posted April 19, 2015 Report Share Posted April 19, 2015 Hi Sorry you had a problem and by the look of it its going to be resolved 😊 Please don't be to harsh its a bit of tube they wear out What is the life expectancy of a multi choke ? There must be many thousands produced and there's bound to be a small percentage fail for a variety of reasons Fortunate it appears no damage done to gun and more important no one hurt Just my thoughts All the best Of Quote Link to comment Share on other sites More sharing options...

I get carbon build up on my Optima chokes both the standard factory set and the flush Briley's which I've used for years. Never been one for finger tightening either, always giving them a gentle twist with the metal choke tool. All depends how many shots you go before cleaning, can't have absolute seal where hot gasses are concerned. Quote Link to comment Share on other sites More sharing options...
Gordon R Posted April 20, 2015 Report Share Posted April 20, 2015 Agreed Hamster. No matter how tight they are, the chances of getting a gas tight seal, at tremendous pressure, are extremely low. Quote Link to comment Share on other sites More sharing options...

Always get a little leakage for sure but that choke in the pic must have been left in the gun for a long time and not fully snugged down. I had Optima HPs for 3 years and was immediately impressed at how much better the gas seal on them was than with other chokes I'd had. The CG Maxis chokes seal very well too. I tend to think that if you're going to post a pic of a broken choke to make a quality comparison, at least find one that hasn't been neglected or mis-used.

The picture was of a standard factory fitted choke that, according to its owner, split on the first day of use. I have no reason to doubt him but if you think that he neglected or abused it in that time frame then you are of course entitled to that opinion.

Westward Posted April 20, 2015 Report Share Posted April 20, 2015 It doesn't take a genius to work out that the choke failed because of carbon build up between the choke and barrel. Either the choke was loose or it was machined wrongly. There's no sign of faulty machining in the pic and it's sitting squarely on the shelf so I tend to believe the choke was loose. What did Beretta/GMK say? Quote Link to comment Share on other sites More sharing options...
Guest cookoff013 Posted April 20, 2015 Report Share Posted April 20, 2015 chokes take a huge amount of force. any miss alignment or gap can be disastrous. i`m just wondering if the skirt section could have been eclipsed (ie gone out of round.) then screwed in, that would cause some issues. i`ve used mainly briley and have been impressed.

widgeon man Posted April 20, 2015 Report Share Posted April 20, 2015 3 years westward??? Wasn't sure the optima hp had been around that long?? I know plenty of fowlers that use and abuse xtrema2's and benelli' utilising the optima system and they are going strong, very few issues...... However the optima hp choke is noticeably thinner, and most aftermarket company's have issued a warning for steel shot through this choke style, due to beretta barrel tolerances and the thinner hp . A lot of swelled chokes in the U.S. Quote Link to comment Share on other sites More sharing options...

Westward Posted April 20, 2015 Report Share Posted April 20, 2015 Optima HP first appeared on the SV10s in (I think) 2009, maybe 2010. The only dfferences I know of are the thread location, conventional notches for the key and the visible part is knurled rather than fluted. Judging by the weight I'm surprised they're thinner and never thought to compare them. CG chokes are noticeably thinner and lighter though. Trouble is there's so much gossip and 'received wisdom' flying round the net. I've scanned the shotgunworld Beretta forum for years and I don't recollect any posts about swelled or bulged HP chokes - but I might have forgotten or missed them. Certainly Beretta chokes generally and HP in particular, don't seem to cause many problems that I hear about. A properly fitted, clean choke is not subjected to high strain levels because the tightness of the threads and the barrel walls provide structural integrity, but if they loosen and the shooter doesn't notice, the carbon build up and sometimes even a pellet jammed behind the skirt, will mean the choke is under increasingly high stress and sometimes destructive strain. Often the threads let go and the choke blows right out - Steve Nutbeam has collected some from the undergrowth at Longridge - or the choke tube is simply wrecked.

Chris Bb Posted April 20, 2015 Report Share Posted April 20, 2015 Agreed Hamster. No matter how tight they are, the chances of getting a gas tight seal, at tremendous pressure, are extremely low. Slightly off topic but I'd suggest that having the thread at the base of the choke should be better than at the top as in the pictures. Thus I'd suggest that, in part, it's a design fault. But, then again, I'm no engineer. Quote Link to comment Share on other sites More sharing options...

On the HP choke the thread was moved back from the muzzle about 1cm. Quote Link to comment Share on other sites More sharing options...
Westward Posted April 20, 2015 Report Share Posted April 20, 2015 A bit of a sweeping statement without any knowledge to substantiate it. A choke with that degree of carbon build up, even after the crack appeared makes neglecting to tighten properly the best assessment that can be made from the available information and certainly much more likely than a manufacturing fault. I thought this thread was meant to be about a failure of a Muller choke... Quote Link to comment Share on other sites More sharing options...
Gordon R Posted April 20, 2015 Report Share Posted April 20, 2015 The thread is supposed to be about the failure of a Muller choke, not having a pop at someone who posted a photo in good faith, only for someone to make a snide remark about the photo. :no: Quote Link to comment Share on other sites More sharing options...
Harnser Posted April 20, 2015 Report Share Posted April 20, 2015 This choke failure looks very much like the failure of some of the hatsan escorts that were posted on here . It looks to me like gas has got behind the choke because of poor manufacture or the choke not being tightened down enough . The hatsans were proberbly down to poor quality control and poor manufacturing process . I would have thought that at 70 Jim each the muller chokes should be well made and not poor quality . Not to sure that I would want aluminium chokes . Harnser Quote Link to comment Share on other sites More sharing options...
activeviii Posted April 20, 2015 Report Share Posted April 20, 2015 Good company awareness and attitude on the Muller, well done. More could take a leaf from this book. As for the Beretta choke failure. Looks to me that it had split early in the day and then the gases have built up unnoticed until the gun was stripped that evening. Every thing fails over time. Bent a piece of metal enough and it will fail. Only takes a bit of slag when the billet was formed and theres the catalyst to failure U2 chokes arnt my thing as I like stainless that I can drop in the ultrasonic and give a good clean. But nothing would stop me buying if I needed. Optima+ use the mid thread too. My urika2 is 2008 Quote Link to comment Share on other sites More sharing options...

Wiggum Posted April 20, 2015 Author Report Share Posted April 20, 2015 Well I've been in contact with Nick a couple of times and the choke is going back to Just choking and Nick is replacing the split choke foc despite me not having the receipt. I have to say the customer service side of things have been absolutely brilliant with Nick being very prompt and understanding in his responses.
