Peely Posted September 14, 2008 Report Share Posted September 14, 2008 Hi All, As the title says, I've been out clay shooting this morning and on some of the pairs the second barrel doesn't want to fire. The first barrel goes off OK and when I come to pull the trigger, it is as though the trigger is stuck. If I release the trigger and pull again it will fire (but by that time the clay is in pieces on the ground). This only happens some of the time, usually in the second half of the shoot and but is not on every stand... I've taken the barrel off when I got home and had a look at the firing pins. The first one (bottom pin) looks to be perfectly central to the hole, but the second one (top pin) seems to be eyelidding the hole a little, would this cause this? If so is this something that can be adjusted? I'm going to phone the gunsmith in the morning but any advice would be greatly appreciated. For info I am shooting with a Lanber O/U 12G Shotgun and using Hull 24g cartridges. Thanks Peely Quote Link to comment Share on other sites More sharing options...
steve_k Posted September 14, 2008 Report Share Posted September 14, 2008 most of the time it is cause by a burr on the faulty pin if you take it out and file the edges slightly then they should be fine Quote Link to comment Share on other sites More sharing options...
Doggone Posted September 14, 2008 Report Share Posted September 14, 2008 I used to shoot a Lanber, and was forever replacing safety catch springs, which caused the problem you describe. I don't know if they've improved the design in the newer models, but I got rid of mine because it was a real pain. Andy Quote Link to comment Share on other sites More sharing options...
slarti54 Posted September 14, 2008 Report Share Posted September 14, 2008 Andy, how do the safety catch springs affect it? They engage the safety without you applying it? Quote Link to comment Share on other sites More sharing options...

CharlieT Posted September 14, 2008 Report Share Posted September 14, 2008 Are you taking your finger off the trigger before taking the second shot. Quote Link to comment Share on other sites More sharing options...
Peely Posted September 14, 2008 Author Report Share Posted September 14, 2008 Are you taking your finger off the trigger before taking the second shot. Yeah, when it first happened this morning. I shot a couple of stands really emphasising the actions, but it still happened. Quote Link to comment Share on other sites More sharing options...
Doggone Posted September 14, 2008 Report Share Posted September 14, 2008 Andy, how do the safety catch springs affect it? They engage the safety without you applying it? On my Lanber half the spring would break or get bent and not allow the kick from the first barrel to move the selector to the second barrel. This is on a single selective trigger, of course.

Doggone Posted September 14, 2008 Report Share Posted September 14, 2008 ] The trigger does feel like I am trying to pull it when the safety is on. Is it an easy job to replace the safety spring? five minute job., butt plate off, long screwdriver to unscrew big screw inside the stock, off comes the stock and all will be revealed, just a small phillips screw holding the spring in place. No particular skill required, just a very long screwdriver. Andy Quote Link to comment Share on other sites More sharing options...
Peely Posted September 14, 2008 Author Report Share Posted September 14, 2008 Thanks Andy, I'll have a look tomorrow night, see what it looks like... Graham Quote Link to comment Share on other sites More sharing options...
viking Posted September 14, 2008 Report Share Posted September 14, 2008 my mate had a dt 10 that kept doing that, took the triger out, gave it a clean, never did it again, easy job a a dt 10 as they just drop straight out, so while you have it in bits give the action a clean, good luck, Lee Quote Link to comment Share on other sites More sharing options...
THEINVISIBLESCARECROW Posted September 15, 2008 Report Share Posted September 15, 2008 Make sure the gun is fully opened when you reload. You might not be resetting the 2nd barrel. One gun I had opened enough for the cart's to come out but needed a gentle push down on the barrels to recock the action fully. Quote Link to comment Share on other sites More sharing options...
Peely Posted September 15, 2008 Author Report Share Posted September 15, 2008 Thanks for the replies guys. I've stripped the action down this evening but there is nothing obviously bent/worn. I think I will take it to the gunsmith on Friday... Thanks Peely Quote Link to comment Share on other sites More sharing options...
Peely Posted September 15, 2008 Author Report Share Posted September 15, 2008 Just out of interest- would reducing the cartridge load from 28g to 24g make any difference? I've only had this problem since I changed to the 24g shells. Quote Link to comment Share on other sites More sharing options...
viking Posted September 16, 2008 Report Share Posted September 16, 2008 no mate, it wouldnt matter what size carts you were using, im sure it will be something or nothing though, let us all know how you get on, cheers, Lee Quote Link to comment Share on other sites More sharing options...
clayman Posted September 17, 2008 Report Share Posted September 17, 2008 If a gun is not firmly mounted, and the action uses inertia blocks, it can happen that the first barrel inertia block does not "set" and the second barrel will then fail to fire. This is a mount problem, usually compounded by lighter or softer recoil cartridge loads. The test is : when it happens next time, without opening the gun, bang the stock firmly back into a solid object ( the ground, a wall, etc) The gun must be securely held and pointing down range or into a safe area when you do this IN CASE it discharges in the process. If, after doing this, the gun now does fire normally, its the inertia blocks not setting that is the problem. Heavier loads, and/or a firmer mount in the shoulder would cure this problem - but as noted by others, there are a number of other reasons the problem could be occurring.

Peely Posted September 21, 2008 Author Report Share Posted September 21, 2008 Evening Guys, Thanks for all of the responses. I took the gun back to the shooting ground that I bought it from and explained the problem. The owner did a couple of tests on the trigger and had a look at the gun, everything looked to be gun, actualy said the trigger pull was quite good. He asked to fire a few of the cartridges that had been causing the problem. Got through a full box nearly (wow! I didn't realise that my gun could hit so many clays, but thats another story...). Anyway, he was happy with the gun and said the same as clayman, that it was either not taking my finger off the trigger fully, or a poor mount that has been accentuated by the lower recoil of the 24g carts. Next time I'm shooting I'll go back to the 28g and try to improve my gun mount - hopefully that should sort it out. Thanks for the advice.
