I bought a replacement lock for my Lyman Great Plains rifle and need to remove the existing lock. I removed the bolt holding the lock in place but I am having trouble getting the lock out of the stock. The front part starts to come out but the rear does not want to move. Is there anything else holding it in place or do I just need to apply more careful pressure near the rear portion of the lock? I also thought about unscrewing the bolt that holds the lock in place a few turns and whacking it with a plastic hammer. I do not want to damage something by accident so I thought I would ask here first.
 
Shouldn't be anything else holding it in.

It may come out easier if you set it at half-cock.

If the inletting is quite tight the straighter you can pull it out, the easier it may come - canting the lock may cause some of the internals to bind up in their inlets.
 
Did you place it on half cock before attempting to remove it? Once you have it on half cock, back out the lock bolt and then tap, not wack the head of the lock bolt to loosen the lock from the lock mortise. It should freely drop out. sometimes, It may drag on the lock mortise but it should come right out.
 
I put mine on full cock, then take the screw out. The lock comes out pretty easily then. YMMV

It's obvious that YOU :thumbsup: , unlike the other yahoos here (except for me) actually read Lyman's instructions that specify to set it at full cock to remove the lock without doing any wood damage :doh:
 
On a percussion gun the barrel sits rather tightly on top of the lock.
This can hold the lock in place even with the lock screw removed so the first thing to do is to remove the barrel.

Then, loosen the lock screw about 2-3 turns and lightly tap the screw head with a small mallet or a screw driver handle. This will break the lock loose from the mortice.

Unscrewing the screw a few more turns and tapping is sometimes helpful.

Remove the screw and your lock should pull out of the stock.
 
Thanks to all for the information. I will have another go at it. I think I had it at half cock when I tried but I will try full and half cock and lightly tapping the screw that holds the lock in place. I did not want to force anything too much until I was sure about how to proceed.
 
Now, you've got it. Easy does it. In instances like this, brut force can cause problems. You did the right thing by asking questions rather than beating or prying when you ran into problems. Any time you run into a problem with muzzleloading, come to this forum and post your question. We'll be more than glad to talk you through it.
