Caliburn Brass Breech Parts
thingiverse
The two parts required to create a brass breech for your Caliburn. Both have a TIGHT fit on 9/16" brass, the goal is to completely immobilize the brass, so sanding will be necessary. Use the two holes on the ram not used for the priming parts to insert a pin through your breech, preventing vacuum loading. I'm working on a tutorial now, but the intent is for one piece of 9/16" brass to be attached to the ram and surround the darts, acting as the sliding breech, while the muzzle holds the 9/16" brass in place in the front for a telescoping barrel with 17/32" brass, which is what the breech slides around.
