Pyropredator Posted January 22, 2017 Report Share Posted January 22, 2017 I recently bought a greener gp in good condition from a local gun shop. After taking it out a few times I have noticed that it seems to pierce the primer on every cartridge I put thought it, I have disassembled the action and looked at the firing pin at full travel and it does not seem to be excessively protruding, although the main/hammer spring itself is very strong. Does anyine have any experience of this and possible remedies or do I just take it back to the gun shop under its 3 month warranty? Is this something they can likely fix? I don't want to take it back and kick up a fuss when it may just be something greeners are renowned for. Just for information I have tried the gun with a number of different cartridges all within the proof and chamber limits, its not that I'm trying to shoot something over these.

Gunman Posted January 22, 2017 Report Share Posted January 22, 2017 IHow far does the pin protrude ? if its more than .070" then its to much . Also check that it is just piercing and not "dragging " which indicates its not cocking quick enough . Best advice is take it back and let some one else sort it out .

klatuveradanikto Posted January 22, 2017 Report Share Posted January 22, 2017 The firing pin can be set to 2 settings in the block the slot has 2 lengths one for short throw one for long throw i guess the slot is set for long throw see martini neal on you tube for info, Hope this helps.

I will try and see if the pin is protruding too much. How would I know if it is dragging? When the gun the fired the pin stays forward as far as I can see. The firing pin can be set to 2 settings in the block the slot has 2 lengths one for short throw one for long throw i guess the slot is set for long throw see martini neal on you tube for info, Hope this helps. I did look at this, the pin is set to the 'softer' longer cutout in the firing pin. Still seems to give a fair old whack to the primers though.

Not sure what you mean , As far as I am aware the Greener GP does not have any facility to alter the pin length . I have a fair few stripped down in my time and seen a lot made and this has never come up . Edited January 23, 2017 by Gunman Quote Link to comment Share on other sites More sharing options...
JJsDad Posted January 23, 2017 Report Share Posted January 23, 2017 The you tube video refers to the Martini Rifle, not the Greener shotgun. The video remark is about the long and short slot being to increase the force of blow, not increase firing pin protrusion. The two are totally different features, increasing the force of blow does not mean an increase in protrusion. Quote Link to comment Share on other sites More sharing options...
theshootist Posted January 25, 2017 Report Share Posted January 25, 2017 All three GPs I've had have delivered larger blows to the primer than any other gun I've used. I've very occasionally had a primer split but I've not let it bother me. Quote Link to comment Share on other sites More sharing options...

I've very occasionally had a primer split but I've not let it bother me. Every cartridge I shoot comes out with a black mark on the primer and a deeper than usual indentation that looks rough at the very end. Is that what you see when you say they have split? I have spoken to the shop I bought it from and they are happy to take a look at it so off it goes on Friday. Quote Link to comment Share on other sites More sharing options...
Evilv Posted February 3, 2017 Report Share Posted February 3, 2017 I just bought a Greener GP the day before yesterday. I'm itching to take it out and try it. It's a 1962 model with 1/4 choke. I stripped the action and cleaned and lubed it yesterday. It was a b*gger to try and fit the block through the top as one set of instructions suggest, but I found another set which described how to put the action parts in through the bottom of the gun and that worked like a dream. It was like assembling lego. No struggle at all. This is the instruction set which made the job easy: http://www.martinihenry.com/policeguns.htm Quote Link to comment Share on other sites More sharing options...
klatuveradanikto Posted February 3, 2017 Report Share Posted February 3, 2017 I reassembled mine from the bottom much easier, looked like it had'nt been cleaned for years ,It says in the paperwork not to dismantel unless necessary but the cleaner in me took over and i could'nt not clean it after use. Won't dismantel it again though as i know it's now cleaned and lubed for many years to come. Quote Link to comment Share on other sites More sharing options...

Won't dismantel it again though as i know it's now cleaned and lubed for many years to come. That's a LOVELY looker. Mine isn't quite that pretty and it has a recoil pad on it which is a shame. I saw a gorgeous one for sale in Liverpool with fantastic case hardening colour on the action, but it is too far. The one I got was 2 miles from my house. Not as nice as yours, but OK. Yes on the dirty internals. Mine is 1962 vintage and a Mark 1 version, and no way was I going to just assume it had any lubricant in it, so apart it came the day I bought it. It had a fair bit of dust inside and was not exactly well oiled. If you want to date them, there is a code on the Proof mark on the action. Here are the codes: 1921 - 1941 guns http://personal.swayzee.com/jayb/datecode1a.jpg 1950 - 1974 guns http://personal.swayzee.com/jayb/datecode2a.jpg There was a period in WW2 and just after when the system was not used or maybe the guns were not made then. Could be there was a war time period when they had other work on - I expect there was. Yours looks like the later Webley one and probably has circlips on the other side retaining the pins. Mide has those funny indexed screws holding the pins in the action. Here is the dealer's picture of mine - like I said - not as nice as yours, though the picture doesn't do it justice.

klatuveradanikto Posted February 3, 2017 Report Share Posted February 3, 2017 Yes mines a later Webley model with circlips not sure of date.Don't like the case hardened look reminds me of doing metalwork in school , pickling and annealing . prefer a nice blue finish.

I wish I'd done MUCH more metalwork at school. I only did it for two years when I was about 12. Learned to chisel metal, file and hack saw, drill, rivet and temper in oil. Just enough to allow me to make a real bodge of most jobs. Quote Link to comment Share on other sites More sharing options...
Gunman Posted February 4, 2017 Report Share Posted February 4, 2017 W&S tried colour casehardening GP's as there was always a problem with blacking the actions . These were castings which when blacked with hot salts always turned purple . Originally Greener blacked the actions by the rust method as they did barrels . I seem to recall that the first GP actions to be cased were a series of trap guns made mainly for the US market that had raised ventilated ribs , full mote carlo stocks with Pachmayr "white line " recoil pads and semi beaver tail type forends . Action pins varied and the split pin , screw and lock screw as well as C clips were used in the 70,s Quote Link to comment Share on other sites More sharing options...
Evilv Posted February 6, 2017 Report Share Posted February 6, 2017 I had my new GP out today and fired it for the first time. What a LOVELY gun! No great recoil which I had expected, not even with the 32 gram, Eley Hi Pheasant loads which bruise my finger with the trigger guard in my side by sides. I shot some paper sheets at 30 and 42 yards wondering how the 1/4 choke would perform, and the patterns were great whether with a 28 gram pigeon load with no 6s or the no5, 32 gram. Even at 42 yards with the no6 I had a killing pattern. The pigeon cartridges are in a plastic shot protecting wad so you'd expect the closer pattern, but the Eleys were fibre and there wasn't a lot of difference once you take account of the smaller pellet count over all with the no5s. I managed to bag a passing Jackdaw - one less to predate the pheasant eggs in the spring. I'm really pleased with this gun, and I think the others will probably get little use now.
