Anybody ever have to put a new extractor in one of these?I can find the parts but am a little baffled on how to get the old one out.Had a big bang shootin the other day and locked it up.Turns out it bent the extractor and I found several spent rem golden bullet casings were bulging at the rim.The one that took it out was blown out all around the bottom,never had a problem with this gun before and I actually own 2 of them.
