PaulJC Posted August 16, 2015 Report Share Posted August 16, 2015 So i took my new to me Lanber Sporting Deluxe to the clay ground for my first ever solo shoot on some clays, i fired 75 rounds, 50 x 21g Eley's and 25 x Lyalvale Power Blue... Occasionally the gun would fail to fire the second chamber, it seemed to happen more on the 21g cartridges than the 28's but tbh i was caught up in the moment and didn't keep count. I have had the stock off and apart from some minor dirt ingress around the trigger opening it was very clean and lubricated probably just the right amount... So with the stock off so i could see what the action is doing and some 'snap caps' in I set about doing some simple testing, first thing i noticed is that the lower chamber requires more 'gun opening' than the second to become cocked, you can open the gun enough for the cartridges to eject/be removed but there is still further travel and it seems the second barrel only becomes cocked properly if you almost fully use this travel, there is not much in it, but there is a definite difference... I dont know if this is normal? Also i think while at the clay ground there may have been a possibility that I wasn't releasing the trigger fully after the first shot, new gun, first solo session, a bit of adrenaline, but i can't really replicate this... But testing shows it to consistently switch from one chamber to the other without any recoil needed, and it appears that being able to just cock one chamber is repeatable (The distance difference isn't great at all, 1-2mm maybe, i wouldn't say it was faulty, just different and something to be mindful of) and was wondering really if anyone had seen this before or if it needs to be looked at?Apart from these few instances the gun handles well and I even managed to hit a few clays so all was not lost and i'm still very pleased with my purchase as i think this was potentially more operator failure than mechanical but thought i'd put it out there for other people opinions and thoughts.

VicW Posted August 16, 2015 Report Share Posted August 16, 2015 Try to determine if the problem only occurs with the 21gm cartridges and not the 28gm . It is possible that with your particular gun the 21gm rounds are not providing enough recoil to cause the barrel changeover mechanism to work. Vic.

Gunman Posted August 16, 2015 Report Share Posted August 16, 2015 If its a 3" as many modern guns are then it is more than likely you need to use a heavier load to make the guns inertia system work . Try different cartridges , Quote Link to comment Share on other sites More sharing options...
ChrisAsh Posted August 16, 2015 Report Share Posted August 16, 2015 Its a new gun so maybe just tight in the action, but you do need to fully open the gun to make sure fully cocked and leaving finger on the trigger after first shot does normally stop the second barrel fireing, Give it a few more boxes preferably with something like 28 gram to see if it improves with better recoil if no change go back to gun shop Quote Link to comment Share on other sites More sharing options...
welshwarrior Posted August 16, 2015 Report Share Posted August 16, 2015 Often if your mount is not firm enough a 21g cartridge won't generate enough recoil to cycle the trigger system. Other issues could be not fully releasing the trigger between shots. And some guns just don't like 21g cartridges but they tend to be older guns before 21gs became common place.

PaulJC Posted August 16, 2015 Author Report Share Posted August 16, 2015 Thanks for the input everyone, the 21g cartridges didn't cause much recoil at all, the gun has a standard Lanber butt pad fitted, is the Lanber a gun that definitely switches over on recoil? I'm quite happy shooting 28g cartridges so will definately be giving that a go next time... Quote Link to comment Share on other sites More sharing options...
hawkfanz Posted August 16, 2015 Report Share Posted August 16, 2015 I have 2 lanber game models both bought new 1 20g 1 12g and yes you do have to break it all the way to make sure bottom barrel cocks also to load bottom chamber I think the springs in the cocking levers are strong and just need using more,never had any issues with 2nd shot not going off.

Dakers Posted August 16, 2015 Report Share Posted August 16, 2015 I had this exact issue on my first ever outing with my Lanber Sporter. I think my mount was poor out of the shoulder and I was using 21g Hull Comp X which are very soft anyway. Once I started mounting it properly it was fine.

Jbob Posted August 17, 2015 Report Share Posted August 17, 2015 I cant say I have ever had this problem with my lanber. I have alway put 28g cartridges through it and even this year when I have started to use 21g eleys the gun has never had problem. I do mount the gun hard against my shoulder though.

GingerCat Posted August 17, 2015 Report Share Posted August 17, 2015 Soft shells with my lanber sometimes do the same. Not often but just thr odd one and that's enough to be annoying. Only happened with 21g comp x. 24g and above are fine. 21g cheddite are fine too but much punchier than the comp x Quote Link to comment Share on other sites More sharing options...
mossy835 Posted August 17, 2015 Report Share Posted August 17, 2015 i have a lanber and all i use is 28grams and works well. Quote Link to comment Share on other sites More sharing options...
bruno22rf Posted August 19, 2015 Report Share Posted August 19, 2015 Have a quick look at the cocking dog-the bit that sticks out from the forend and cocks the hammers-my Lanber wore the dog away in 3 years. Quote Link to comment Share on other sites More sharing options...
ShootingEgg Posted August 19, 2015 Report Share Posted August 19, 2015 One thing ive not seen/read here(i may have missed it) is switch barrels on selector and fire what would be second barrel first. Then u could see if its due to not cocking or if it fires and then second doesnt its possible cartridge isbt activating the recoil switch?

NorfolkAYA Posted August 19, 2015 Report Share Posted August 19, 2015 I had the exact same thing with mine. Took it to the gun smith and was told the inertia block had a slight bur on it causing it not to switch over to the second barrel. Mine was fine using 32g but not 28grm. It's all sorted now and works as it should with any cartridge. ATB If you dry fire it and then smack the butt pad with the palm of your hand see if it will fire the second barrel then. If it works I would presume it is the inertia block. Quote Link to comment Share on other sites More sharing options...
PaulJC Posted August 19, 2015 Author Report Share Posted August 19, 2015 Thanks everyone for your input, sorry for the delay in replying, it's been a busy weekend... I'm not going to have the chance to get out until probably Wednesday but i'm planning on running maybe 100 x 28g cartridges through it and keeping track of any issues (and if i can hit anything lol), good couple of points brought up here which i will make sure to look at... When dry fire testing here most times it would happily fire both barrels without any kind of inertia involved at all, just happily click, click with 2 trigger pulls so who knows... I'll put some rounds through it and see when i get the chance Quote Link to comment Share on other sites More sharing options...

kent Posted August 20, 2015 Report Share Posted August 20, 2015 As many have said not enough recoil to set the second shot Just note if you get a fail to open after firing the first point the muzzles in a safe direction and bump the butt - once saw a guy drive to the gunsmith with his family in the car with a gun in this dangerous state He went white as a sheet when he was taken outside the butt given s thus and the shell discharged into the field Quote Link to comment Share on other sites More sharing options...
PaulJC Posted August 21, 2015 Author Report Share Posted August 21, 2015 Still not had a chance to go shooting but have had it out and tried the fire,bump,fire which seems to work consistently so i am thinking not enough recoil as well now, as said above i'll be putting some 28's through it over the next few days and will see how that goes...

I never leave the stand until it's broken and empty, if for any reason i couldn't break it i'd take it apart if i had to before i moved tbh...

PaulJC Posted August 24, 2015 Author Report Share Posted August 24, 2015 Managed to get out today (In the peeing rain) and got 100 cartridges through it and all was fine, so possibly the lighter cartridges caused it, possibly the light lube up i gave the selector helped, and maybe the operator failed less today... That said though, i probably only hit 10-15/50 but it's a start... lol Quote Link to comment Share on other sites More sharing options...
