I need help,I purchased a brand new Napier cleaning kit,cleaned 2 rifles,first 1 was 22 PCP 2 was 177 pcp 3rd 177 PCP I was on my last pull on the 3rd and it snapped in the barrel and I can't get it out it's about 5 inches from the end of the barrel, I've looked at the end of the pulley, that braid they use just slipped out of the crimp inside as the outside has a rubber sleeve,gun shop I brought it from said try shooting it out without using pellets i tried 3 times and it didn't sound good, now they have said buy a thin steel rod and try to ram it down,any idea please, let's say I'm not happy
