[QUOTE="fmuguira, post: 2414075, member: 27974"] My Rem 700 257 WB definitely has WB freebore!!! I can touch the lands at 3.680 with both 110 AB and 115 BT. That has the bullet base right at longest front edge of case neck. NO bullet engaging neck! I load to 3.430 oal so still jumping .250!! Reason I went this long is my rifle shot best here. 3/4” groups typically. Trying the 3.170 SAAMI, trying 3.270” recommended by Layne Simpson in article he penned all shot 1 1/4” ish. Good luck but I would definitely try some big seating depth changes to start. You can fine tune .010, etc once you get a starting point. Remember to shoot groups SLOWLY with that Bad Boy!! He ll generate some heat. [/QUOTE]
