    picked up a lyman great plains today nib seems like a decent rifle. only negative is the hammer on the lock just baaaarly clips the nipple. it does fire a cap every time. a little disapointed in that the hammer isnt square to the nipple.

    range report and pics later saturday

    Filed the nipple down some and it now strikes without edge contact.

    Lol

    I think its odd to call the priming stem a nipple. Damn thing looks nothing like what a nipple is attached to...

    But then you also got nipple picks and wrenches.

    Jon when you file a nipple off you dull the edge. The cap or top of nipple must be sharp to provide dependable ignition. A flattened anvil on the top of a nipple is not good.
    The problem you have encountered is common on mass produced BP firearms. The cure is to remove the hammer heat it bend it harden it replace. :)

    A nipple is a short piece of pipe used to join 2 different sizes of pipe. The nipple is usually a threaded male end. :)

    Put in a shorter nipple, or check to see if nipple is screwed all the way in !...............

    Use a standard #11 Percussion Rifle nipple. Never use a short threaded pistol nipples in a rifle. That is good way to get hurt very bad. This is a hammer angle problem.:)

    Do you have a drum or a snail? My first BP rifle (still have it) has a drum and it was not lined up right so the hammer would not strike the nipple square. Used a wrench and vise to turn the drum, problem fixed. Same issue with a Hawken, so no drum to turn. Had to take the hammer off, heat it and give it a bend. Once fitted, I heated it and dunked it in mineral oil. Been working for 10 years. You would think they would never leave the factory that way???

    The lyman gpr has I guess you would call a drum it makes a 90degree turn. Its got a set screw so you can clean into the barrel channel.

    I'm not using a shorter one I just took a few wacks with a file and its clearing the hang point now. If I loosen the drum as it would need to be rotated rearward I would think it would work itself free and become loose under firing.

    it did just fine managed to get one group just under the 2 inch mark most were at 2-3 inches.

    fired about 50 rounds until i screwed up and didnt fully get the solvent out of the barrel before putting in a charge soaking it down maiking it no longer go boom.

    left the ball getter outer at home so called it a day.

    really happy with this rifle altho the rear sight sucks. my mosins have better rear sights than this lyman rifle does. the front sight is wide but thats ok for a 100 yard gun but the rear is just aweful.

    The Lyman Great Plains has a snail breech. It doesn't move as its part of the breech plug.

    Ahh ok. I'm not that familiar with bp guns and their design.

    Is the breech plug on these lyman guns removable for thorough cleaning??

    You can get it off but it takes some doing and is not recommended. I remove the barrel from my .54 Hawken and stick the breech in a bucket of water. I use a 20 gauge bore mop and it pulls water up through the bore and pushes it back out the nipple. A tight patch on a jag will do the same thing.
