I have a Briley thinwall choke tube stuck in my wifes BT99. It was lubed but about 400 round have been shot through it over the past 6 weeks. I've been soaking it in Knao Kroil for about two days now and it's still stuck. Not sure how much tork I should apply trying to free it, but I've definently put some weight behind it and it hasn't budged. Any other suggestions?
