I spoke to Bobby Hart about this issue with the J Lock. He said that he had built hundreds of long range rifles with J locks on them to on ill effect.
Mr Hart said that when you cock the bolt on a J Lock rifle, if you hear a lot of grinding, the firing pin spring is binding up against the inside of the bolt body. If you do not hear the grinding, then there is no problem with that particular J lock system.
Side note, the Rem 783 has one of the fastest lock times of any action made, faster than the rem 788.
