kirk - having your Mr. Wakeman saying that he doubtsthe T/C 1:48 barrel would ever be a real tack driver is not a true statement. I've had a couple of these barrels that were extremely accurate. I have a 54 cal right now that will shoot cloverleaf clusters of PRBs at 50 yds without any trouble.
IMO most all MLs will be good shooters once you find the magic combination of powder and bullet. But to me that's part of the fun in shooting them.
