RE: CVA Breech Plug
Bass Pro should have them in stock for less than $20. Sportsmans Warehouse also stocks them. The Winchester BP is the same thing so check and see if they have that one. Also I would press BPI/CVA for a new one at no charge, it does have a lifetime garantee and should not have broken. That way you will have a backup.Mine is 5 years old and I've not had any problems with it. BPI recently sent me (free)oneof the newer designs (like theOptima and Kodiak use)to try out in my Magbolt and it works also.
Good luck with it.
