That stock needs the proper barrel it was inlet for. Opening up the rod hole from the top is OK to finish the rod hole.
I'm sure that barrel is available.
Breech 0.956
13” 0.775
Looks like a description of the Colerain 38” Swamped Early American style barrel. Fair enough. I don’t think I’m skilled enough to adapt a different lock to this so I’ll
Need a Ketland lock. Trigger guard, buttplate maybe order, maybe attempt to make a model then sand cast. I incidentally have a 6kg melting furnace coming that is for a different project. Nice thing about casting stuff is if it turns out wonky back into the furnace it goes!
Note- none of this project will interfere with my main rifle project - a soon to be ordered Woodrunner kit from Kibler. This is all just stuff to practice on.
Anyway I’ll prob do some sort of video series on it so I have it for myself for future projects.
Cheers to the folks who have encouraged me to do more than just whittle on this lovely bit of wood.
