My little brother is getting his first muzzleloader for christmas. It is aCVA buckhorn( astrait cocking inline)My parents called me and asked what accessories they should get him.( I am the only muzzleloader hunter they know). Anyhow they brought up the question of hunting in foul weather and asked how to weatherproof the muzzleloader. I told them what I knew about how to cover the end of the barrel but I dont know what to do with the primer end of the barrel. Any sugestions would help.
