i got my son his first muzzle loader. it was a bobcat. not to happy with it. we have to prime it everytime we shoot or it will misfire. is there anything we can do. our season opened yesterday, and he got a doe and a 250 pound boar which is good, but a misfire on his buck this morning was a real let down for a nine year old. i know there cheap, but you shouldn't have to go through this everytime you shoot. any comments would help, thanks
