Have a new Bartlein Blank, 7mm (.284), 8 twist, #4 Bull Sporter. I'd like to trade this for a quality 308 Caliber blank, 10 or 11 twist in a sporter contour. #3 would be my preference I'd prefer a cut rifled barrel but a good button barrel would be fine as well. Lija, Shilen, etc. Alternatively I would sell for $265 shipped.
