All excellent points, Pete. Thanks for replying.

As to the prevention of moisture intrusion, when I used to build m/l longrifles I would seal the lock inlet, barrel channel and tang, and all other unseen places where wood is not finished with shellac. It has seemed to hold up very well over a good many years. I've got some built and finished this way back to '86, I think, and no problems.

Thanks.

May God bless America and those who defend her.
