Well that's the thing, this rifle I am building is a learning experience and, while I am at it, I want to turn out something as good as possible. The 3/32 sounds pretty good and with the beeswax it should not show up, I'll probably go with that.
Which brings up yet another question. Some wedges are slotted for a pin, to retain them. This gun I am building will be a back up for any hunts into remote areas. That is the plan. In any event the idea of retaining a wedge seems vaild- don't want to lose one in a place where I can't get another.
Some pins are set inside the barrel channel- again- that seems like a blind hole and taking the pin out would be a problem if the wedge needed work. Another method I have seen is the pin in a slot right under the wedge plate, off hand that would seem to make more sense because the wedge plate could be removed to in turn remove the pin if the wedge had to be replaced.
