Hi there: I have a new Shadow that has barely 1000 rounds thru it. I noticed it is shooting high for about 6 inches at 25 meters from a bench. However when I was trying to figure out things, I noticed the barrel bit has what appears to be excessive wear marks on and around the nipple. I have loaded the pictures here. Is this normal? It is hard to believe it is! Sent from my Nexus 6P using Tapatalk
