GPR problems/questions

[Murf425]

I took my new GPR out to the range today for the first time, and I have some issues.

First, my CCI #11 caps don't fit on the nipple. They only go about halfway on, so they take two or three snaps before they fire. My question is, should I get new caps or a new nipple first? Which is more likely to be the culprit? If I order a new nipple, how do I make sure that the replacement I get has the right threads?

Second, the set trigger every now and then wouldn't work. I'd pull it, hear a snap, but then still have to pull the front trigger real hard to fire. Any ideas?

are you sure you have #11's and not #10's? if so, remove the nipple and spend a couple of minutes with a file and run the diameter down a bit. as far as the trigger is concerned, take it out, take it apart, clean it, polish friction point, oil it and your done. unfortunatly lyman triggers blow. or you could look up R.E. Davis, and get their deerslayer trigger, its basically a drop in, and only $40 from davis directly

As far as the nipples and caps, I fine tune all of my guns for a custom fit to the caps I use. Just take the nipple out, chuck it in a drill and hold a file to the area that the cap sits on till you get a good fit.

GPR factory nipples are notorious for being difficult to fit with #11 caps. Chuck it up in a drill and file it down as indicated in the above post. I just chamfered the outside edge of mine by hand and it worked fine. Late I bought a hot shot replacement nipple and never had any problems thereafter.

As far as your trigger problem, if the triggers and lock both work fine out of the stock, you probably have a bit of wood hanging up the trigger bar somewhere. Remove the triggers, use some bright lipstick on the top of the trigger bars. Reinstall the triggers and operate them. Remove the triggers and remove any wood marked by the lipstick. Repeat as necessary.

If you decide to chuck your rifles nipple in a electric drill and lightly file the cone down, locate the chuck jaws on the solid body of the nipple, not on the threads.

Clamping on the threads with a drill chuck can deform them. If this happens, when you screw the damaged nipples threads back into the barrel it will damage the nipple threads in the barrels breech plug.

Also, if you use a small flat file to reduce the cone size, check often with a cap for a proper fit. It doesn't take a lot of material removal to make a real difference and you don't want the nipple to be undersize.

Get a Hot Shot nipple for it & make sure it says it is gor aGPR. They are metric so a standard nipple will not fit it correctly.

As for the trigger, normally the GPR triggers need a lil polishing & etc. and they work just fine. All they usually need is a lil fine tuning. As suggested, could be the wood is hanging up the triggers. Have not seen a GPR yet that couldn't be made to work fine with the existing parts, just needs a lil TLC.

Thanks for the info, guys. I'll be trying to fix the nipple this afternoon, and I think I may have fixed the trigger. I don't really know what it is or how it works, but the adjustment screw between the triggers seems to have done the trick. I back it out a half turn, and now she seems to work like a champ.

Yes I agree with the advice to buy another new nipple. They are metric so bewares when buying. (6 x 75 mm I believe is the size)

You have wood binding the triggers. Use lipstick or a red china marker on the trigger bars to find the hang up. Cut the wood out but be careful not to mar the inside edges of the trigger cavity with your tool!

Then go to Ace Hardware and buy a longer trigger adjustment screw. Cut and file it down to where you like the trigger pressure. Cold blue the screw head and the factory triggers will be just fine (for the set triggers). There's not much hope for making front trigger alone into much more than as is.

You will love that rifle. They are fantastic shooters!
