Paddy Galore! Posted February 6, 2010 Report Share Posted February 6, 2010 hi, i recently posted a topic about this subject and was advised to take it to a gunsmith. Well, i did that and i'm still having grief with anything under 32g. The gunsmith told me there was nothing wrong that he could see, it hasn't been shot much, and i've taken to using graphite grease on the moving parts as this seems to help. Only problem is the dirt really sticks to this and i end up back at square one after about 100 shots. I was wondering, has anyone else had this and did they manage to sort it? what cartridges would you recommend? thanks in advance, gram Quote Link to comment Share on other sites More sharing options...
neil smith Posted February 7, 2010 Report Share Posted February 7, 2010 Hi Gram What kind of problem are you having ? Does it fail to eject the fired case ? Does it eject the fired round but fail to feed a fresh cartridge from the magazine fully onto the lifter plate ? Does it eject the fired round but the new round fails to enter the barrel correctly ? the type of stoppage your getting can point to a different cause. Some M3s used for PSG were never fully cured of this problem, which is why the M2 is the more popular gun, that said it could be something easy. Also have you ever removed the stock or replaced it with a pistol grip type ? N Quote Link to comment Share on other sites More sharing options...
hogey Posted February 7, 2010 Report Share Posted February 7, 2010 my son has a W&S semi auto and had the same trouble.tried using 70mm cartridges and it now works fine.give it a go might do the trick Quote Link to comment Share on other sites More sharing options...
Paddy Galore! Posted February 7, 2010 Author Report Share Posted February 7, 2010 Hi chaps, i'll try to be more specific.. firstly, the cartridges dont eject fully, there seems to be 2 points where the bolt assembly will stop, if the cartridges don't give enough recoil then the bolt only slides back to the 1st stop which doesn't reach the ejector pin hence no ejection. with the heavier stuff there seems to be enough recoil generated to push the bolt past this false lock and fully retracts to the 2nd stop which engages the ejector pin and chucks the spent shell out. I must add that i only use 70mm catridges, as 65mm just dont work whatever the weight, and yes it has a pistol grip [M3 super 90] It will cycle fast 28g loads for a short while, RC2 28g#6 & game bore black gold 28g#8 being the most successful so far, but dammit these puppies are expensive!

Gram71 try striping the bolt and cleaning of all the grease replace with a good gun oil between the 2 parts of the bolt were they rotate and reassemble gun and try that . running the bolt dry is the main problem for Benellis not running properly and the moly grease is probably slowing down the bolt as well . also the tube in the stock where the rats tail runs on the bolt needs to be lightly oiled as well hope that this helps you ? .

saggy61 Posted February 7, 2010 Report Share Posted February 7, 2010 Get rid and buy your self a Beretta, much more reliability Quote Link to comment Share on other sites More sharing options...
neil smith Posted February 7, 2010 Report Share Posted February 7, 2010 (edited) Gram I think we are getting somewhere now. First there should be no 1st & 2nd stoping points for the bolt, it should track backwards & forwards in a smooth fashion. It sounds to me like you have a "binding" problem which is common when pistol grip stocks are fitted to Benelli's The recoil spring which is housed in a guide tube, located inside the buttstock, & which also holds the stock on the gun via a nut screwed onto it can become out of alignment on the pistol grip models, if the stock has been overtightened the tube tends to "flex" creating a tight point. This causes the recoil springs follower to "bind" at some point inside the tube, (which is why you bolt feels like it stops twice) try slacking off the stock nut & shoot the gun with it slightly loose, if the gun works then that is the problem. The spring follower that binds is the part that the "tail" of the benelli bolt sits into when you look into the action with the trigger group removed, if you push it you will notice its under spring tension, the follower must be free to move inside its tube. To cure it you must be sure that you are not causing the tube to flex when tightening the stock, its not easy, you may need to dremmel some material from the stock & try it again, standard straight stocks dont have the problem.

Paddy Galore! Posted February 8, 2010 Author Report Share Posted February 8, 2010 OK chaps i'll give it a go and have a looksee, never did think about the stock so thanks for pointing this out, i'll let you know how i get on.Thanks! Quote Link to comment Share on other sites More sharing options...
RC45 Posted February 8, 2010 Report Share Posted February 8, 2010 Mine won't cycle anything below 28. I think that is the nature of semi's. Your should still cycle 28's though. Quote Link to comment Share on other sites More sharing options...
Paddy Galore! Posted February 10, 2010 Author Report Share Posted February 10, 2010 Mine won't cycle anything below 28. I think that is the nature of semi's. Your should still cycle 28's though. It does for a while mate, but soon gets dirty and sticks. Anyway, had a play with it tonight, took the trigger mechanism out and it travels very smoothly backwards and forwards. Went as far as stripping it down to every nut and bolt, cleaned it, used the oil that came with the gun, put it back together, and although i'm not sure exactly which part is causing the problem, it's definitely in the trigger assembly. Gonna call GMK and ask them to sort it out tomorrow, or at least see if there's any modification that can rectify the problem. Failing that i might just have to start home loading some 32g clay loads By the way, neil, thanks for the advice, it didn't work but it filled up an otherwise boring afternoon. :blink: :blink: Quote Link to comment Share on other sites More sharing options...
