I’m not sure what you mean by stubbing but, a friend sent a barrel to Hoyt and we will be trying to fix it. The front half of the barrel was replaced with the rear half turned to a sleeve that went threw the rear half to the breech. That preserves the breech end with the sight but replaces the front half and complete bore. After getting it back the breech will have to be reworked as his work is un-satisfactory.
