Why do you want to remove it?

Re: Breech plug-Lyman GPH rifle ?

I found one,used,but the bore is so rusty,a patch will not go thru and back out. When you do get it up out it is covered in rust. I figured,if,i could get the breech open,i could try to polish it up with valve compound?
Any other ideas?????
To replace the barrel,i might as well buy a new GPH.

I know a guy that took his deer stalker to a gunsmith and had it made into a removeable breechplug. Ofcourse this would void the warranty.

Try some 000 steelwool and oil,on a jag,see if that will get the rust out,if it does you can use Butch bore shine after the steelwool.

Start with a smaller jag and thicker patch, with a greasy abrasive, like J&B Worse that can happen is you have it reamed to a smooth bore.

You could also try the white auto buffing compound that comes in a flat round tin like wax. The red stuff is far coarser.

Absolutely try all of these free, serious recommendations!

The barrel of this rifle is absolutely worthless if it is found to be severely rusted and pitted. With deep pitting, your choices are two fold:
Buy a new barrel, or ream the original to smoothbore.

Do Not enter the magical world of flintlocks accepting any degree of metal rust, inside or outside the mechanics of the weapon. You don't accept rust on your modern weapons, so require the same of these much more valuable long guns!

If this is too much personal effort and involvement with flintlock long guns, then consider compound bows.

No need to remove that breech plug.Breech area is about a 30 cal.Soak with PB Blaster then scrub.Bore scrub with PB Blaster,jag,and 0000 steel wool.Work it,you will get it polished up.

The answers to all of life's questions are found in the Bible!

Re: Breech plug-Lyman GPH rifle ?

Good recommendations! However, if the barrel is pitted, no manner of cleaning, scrubbing, or steel-wooling will remove the pitting.

It will shoot, and will perform to some limited degree of accuracy, but a pitted barrel remains a pitted barrel.

If it is offered CHEAPLY, think twice before purchasing! This is absolutely no way to begin the wonderful experience of the uniqueness of flintlocks! Having them function properly isn't that difficult.

The heart of a flintlock is the lock itself. If the lock isn't tuned properly, if the flint isn't sharp and striking the frizzen with sparks flashing downward into the pan, if the pan is overfilled with priming powder, and, if the touch hole isn't properly cleared to the main charge, then, the result of pulling the trigger will be a serious disappointment!

There is absolutely nothing magical about using flintlock weapons, it is simply common sense. Our Revolutionary War recounts the importance of Pennsylvania flintlock rifle regiments. Their success with using rifles with flintlocks didn't require "how-to-use" manuals. It's the same today.
