The bores are pretty good. No pitting, just light rust that cleaned out nicely with a lead lap and emery.  Shot a couple hundred linen patches through two rifles. Trouble was the linen is too coarse. Looks like fine burlap. Lots of linen out there. A lot of it is part linen part cotton. Some is cotton they say is linen. People lie to sell stuff. most of the linens are to low a thread count and to thick. Did find some linen that looks right at a silk supplier in India. Tried to buy some online but have to have a paypal account. I dont do paypal. 
The linen I used felt much smoother and slicker than cotton patches. They blew out to fuzz balls with only forty grains of powder.

leadball,
The diameter of the of the nose forming part of the mold, the brass part that you can see inside the mold, is .365. The diameter of the rod extending out of it is .312 so, it goes in the front of the opening and goes through the bottom of the mold. The inside of the mold has three diameters, base band, bore riding and .3135 reamed through. The spring is captured between the bottom of the mold and the nut and washer on the end. The nose area bottoms out and the spring holds it there. You cast the bullet, cut the spue, turn upside down and tap the nut end and the bullet falls free.

In this way, if the bullet is to long for the twist, you just make a spacer to put under the nose forming part and shorten it by what ever amount you want.

In case anyone should get a German percussion schuetzen rifle and wishes to use the correct traditional style bullet, this may help.
