Don,
Scott barrels are lead lapped and he will cone them free of charge. He does straights, tapers, and Oct-rnds. He'll do custom orders but I don't believe he's tooled up for swamps. Saw one of his in a Don Pitch rifle on Track a while back that was square for the first 9" then Oct. Don told me he like doing business with Scott because he could get what he wanted in a timely fashion. I have a straight barrel from Scott that I'm building a southern rifle around at the moment. Was pretty impressed. The straight barrel I got was $145 + $10 shipping and he had it mailed out to me as soon as he got my check. Outside finish is very slick as is the inside.
If you call him, you'll probably get an aswering machine. He will get back to you pretty quickly.
