went to the college gym a chadron ne. to try to keep alive to day . on the way home i passed by the museum of the fur trade and it was open. paid my 5 dollars and spent about a couple of hours their. saw in close detail up front in my eyes a couple of hundred stone locks trade rifle to the natives. this is what i saw. some of the holes were at the place most of you said they should be. but most were not. from what ive read by most of you stone lock experts is that the touch hole should be cut in half by the part that the powder lies in. most were not. also i could tell that most touch holes were bigger than 1/16 th. some alot larger. so i figured this. those guns went off well and the holes were a lot largwer than 1/16 th and they were well below the the frizzen or what ever you call it and they still went of and served the natives well. so what is the real skinny on rock locs. fill me in on the real practical deal as i saw it today and im sure all these guns served their owners well.
