I own four, the 8400 7WSM is stock and there is no need to change it. The 223 didn't shoot good enough for me so that was my excuse to have an 8 twist barrel installed. The last two were donors, one is now an 8 twist 6x47L and the other a 6.5x47L, all the barrels sold for a 100.00+ each.
A SS 700 or 70 action plus a Mickey stock will cost about as much as a used Kimber donor.
