Cosd Posted June 28, 2010 Report Share Posted June 28, 2010 I have recently started shooting with a Benelli 121 SL80 3 shot semi. I had two types of cartridges on me on my first outing with the gun, 32g no6 60mm (ish) and 30g no6 55mm (ish) Admittedly I only tried once but having loaded three of the 30g cartridges the first spent cartridge was not ejected cleanly from the gun and got stuck. I didn't give it a second chance, I took all three cartridges out and loaded again with the 32g ones which fired and ejected well. I am due to go out this Thursday and called the gunshop to check stock for the 32g Rio's; He hasn't got any to that spec instead he has 30g no6 60mm or 32g no6 55mm. So what is the problem? did the gun not like the length or the weight? Or did I just get excited too quickly (no wise cracks from my wife if she is reading this) and I should have put a few more of the 30g cartridges to try them again before concluding they didn't work? I need to get a slab for Thursday and don't have time to try a box before buying..... Quote Link to comment Share on other sites More sharing options...
Breastman Posted June 28, 2010 Report Share Posted June 28, 2010 Assuming the gun is in good working order at those weights its more likely to be the length of the cartridges. Either stick to the length the gun is chambered for or one size less, e.g. If its a 3" (76mm) chamber try not to go below 2 3/4" (70mm) etc. To be fair though if you 'abandoned ship' after ONE cartridge you're probably not giving you gun a chance, especially if it s new Benelli as they sometimes need 'breaking in'.

Breastman Posted June 28, 2010 Report Share Posted June 28, 2010 Try it with cartridges its chambered for are my only thoughts then. 60mm and 55mm seem very short, especially to be putting in a semi. Remember cartridge length refers to the fired case length, not unfired. The length of the cartridge should be taken from the box the carts come in. If its still playing up take it back to whoever you bought it from to get fixed, or it thats not possible a gunsmith to check the recoil spring strength.

Paddy Galore! Posted June 28, 2010 Report Share Posted June 28, 2010 As it's a benelli then stick with the longer carts, the measurements you've given are a bit confusing, what does it say on the box? My guess would be the longer are 70mm(2&3/4), and the shorter are 65mm(2.5") these are the sizes after the shot is fired. Most, if not all benelli semis are cartridge fussy.

Most, if not all benelli semis are cartridge fussy. Sorry the sizes mentioned are from me measuring a live cartirdge. The smaller ones say 67mm on the box, I don't have any boxes for the longer ones but they are about 5mm longer So I think by the 2 posts I've had my question is answered, its the length that counts, which means I can get the 2 3/4" 30g ones.

Cosd Posted June 28, 2010 Author Report Share Posted June 28, 2010 Just called to get some prices, DnJ's 32g 6's £42.50 a slab, next best price is £50!! Are the DnJ's that bad? I'm allowed to hijack my own thread.... Quote Link to comment Share on other sites More sharing options...
EastSussexLad Posted June 28, 2010 Report Share Posted June 28, 2010 I went through 500 last season, a lot of people don't like them for some reason - I couldn't see why when i was using them cracking little cartridge. Quote Link to comment Share on other sites More sharing options...
docholiday Posted June 28, 2010 Report Share Posted June 28, 2010 I would persevere, and make sure its cleaned, my Urika does the same on rare occasions.I used brake cleaner to clean the gas ports doc Quote Link to comment Share on other sites More sharing options...
UKPoacher Posted June 28, 2010 Report Share Posted June 28, 2010 I've just got a Benelli 121 and it cycles standard Winchester 28g No. 7.5 cartridges without a problem. Same with Lyvale 30g and Gamebore 32g No 6's. Lovely gun too Quote Link to comment Share on other sites More sharing options...
mudpatten Posted June 28, 2010 Report Share Posted June 28, 2010 It`s got nothing to do with the length of the cartridge. A "run in" inertia operated Benelli will happily function all day with 65mm cartridges provided they generate enough kinetic energy to operate the mechanism. Although this does`nt help `cause they don`t put this figure on the box, but the cartridge should generate a minimum of 180kg of kinetic energy.(Thrust? recoil?) Some 65mm cartridges will easily do this whilst most won`t. Since with light load short cartridges you`re operating right on the functionality borderline such issues as the cleanliness of the gun, the way you hold it and even your physical size can have a bearing on whether it works or not. Or just use 70mm cases and a minimum of 1 1/16oz. to make sure. Quote Link to comment Share on other sites More sharing options...

Sorry chap but i do believe you are talking out of your crimper, my M3 didn't, and i know for a fact that benelli had so many sent back due to this problem.

mudpatten Posted June 29, 2010 Report Share Posted June 29, 2010 Sorry if this sounds a bit muffled but my SBE 2 must be worth a small fortune since I can randomly load any three from the following - 3.5", 2 3/4",67mm or 65mm and it will spit them out in any order that you care to insert them, provided that, with the short`uns they GENERATE ADEQUATE KINETIC ENERGY. So will the Benelli`s of at least three other people I know. If the cartridge has enough punch and the gun is "loosened up", it will work. Many Benelli owners think their gun is faulty since it won`t cycle very light loads. They are not designed to and this is clearly stated in the advertising blurb. If the gun is working the cartridge must be generating enough recoil. If the gun does`nt cycle then the cartridge is`nt kicking enough. The actual physical length of the cartridge plays no part in any of this. Quote Link to comment Share on other sites More sharing options...
