I think that you will have great difficulty in trying to free-float the barrel in your Bell & Carlson Alaskan II stock , as it is designed to have an upward pressure point at the fore-end under the barrel . Read the note beneath the description of the Alaskan II in MIDWAY USA website .
When you tighten your action screws to the proper torque , it will cause the fore-end to raise up to contact the barrel , just forward of the front sling stud .
Call Bell & Carlson to verify if what I say is correct .
I have a Weatherby Mark V , mounted in a B & C Medalist stock , that had the very same problem . The stock is made with 2 aluminum arms that are part of the bedding block system , and these arms extend full-length forward of the recoil lug area , one along each side of the stock .
When the action screws are tightened , the arms are leveraged upward , to create a pressure point under the barrel . This was quoted , and explained , to me by Bell & Carlson customer service .
In order to free-float my barrel , I had to cut these 2 arms , just forward of the recoil lug , removing a 1/4" section out of each rail , then repaired the stock using Marine-Tex epoxy .
Problem eliminated , barrel now free-floats , and accuracy greatly improved .
By the way , I have a Remington Sendero 7MM Rem. Mag. that shoots very well using 162 gr. A-MAX bullets , Fed.215 primers , H4831 powder , and Winchester brass . 26" factory barrel @ 3020 F.P.S.
GOOD LUCK .
