I bought a Snider musket several years ago & discovered 1st round it had a bulged chamber. Had to smack the case a LICK to get it out & it was ruined for reloading.
Stood it against the wall and FINALLY found a barreled receiver. Got that in to discover the breech block wouldn't open. Finally drifted the hinge pin out and used a long punch to drive the locking pin forward to release the breech block from the receiver.
Started out like this. Breech block would NOT budge.

After the steps mentioned above, got it off to find no issues.

Root cause of the trouble - solidified yak fat. I'm not making this up - not much for petroleum based preservatives or grease in Nepal so they used yak fat. No - it doesn't smell very nice.
Shown here is the hinge pin (top) and locking pin. Both were nearly immovable. Got them soaking in alcohol now. I figure 2 or 3 days should soften the yak fat.

Side shot of the breech block. What a mess! I think the gun was only given a cursory cleaning when it was removed from the crate. Certainly not in a dedicated parts cleaner. The breech block itself was partially stuck. Took gentle tapping with a nylon hammer to get it out.

I'm pretty sure this gun was native made. Due to my crappy photography, it's not too clear, but it looks like strips of metal were forge welded around a mandrel. There's no pitting, so it really doesn't worry me about safe firing.

I was concerned about barrel condition but it was excellent. Yak fat is a great metal preservative. I've never seen a bad yak fat barrel! No bulges, dents or mud dauber nests.
And just for grins, here's a comparison shot of 577 Snider vs 45-70.

Profuse apologies for the bad photography. I was too lazy to go back downstairs for a reshoot.
Next up - after mucho elbow grease and scrubbing is swapping out parts and test fire. SW
