Ok, everything I've come across thus far says the chamber is included in the barrel length. I have an old winchester '97 that a previous owner cut down. Took it to the local auction yesterday, and they refused to sell it, said it was too short. Their gun "expert" says chamber doesnt count. Said he had a HLS officer look at it and say he wouldnt pass it. Can somebody clear this up for me, or where I can find it in the legal literature? Thanks.
