Well i guess my main question/concern is:
The rail and action are both steel...the chassis is aluminum and polymer, and shouldnt need anymore than a skim bed...but since its not steel do i need a diff compound than i would use with the steel on steel...i hope that clarifys my question more.
This is my 1st custom so wanna make sure i do it right the 1st time.
I have done many bedding jobs with devcon. Recently my gunsmith buddy suggested marine tex because that's what "all the winners" use (His words not mine). So I tried it. It is good stuff. Seems just as easy to use as devcon. Cost is similar. I would think either one will stick to any material stock you would use it on with proper prep work. I have previously bedded the action and the 20MOA rail both. Now I usually don't fool with the rail but could still be beneficial.
Was thinking Devcon for the rail and Marine Tex or Acra Glas for the chassis due to the polymer...but i wanted to check 1st and see what has worked for others.
I have done a bunch of rifles with JB Weld. I pillar bed with 3/8's stainless tubing and use spray on canola oil for a release agent. My rifles are going good with some 10 or more years old bed jobs and heavy recoil. I use the slow cure and twist the action screws at 4 hours to make sure they are loose and break any bond on them. Make sure everything is really sprayed so you do not have to take the action out with a hatchet! lol
I had good luck with jb weld on my vs swift. I used earnie the gunsmith bedhead shims to shim the action out of the hs stock. I put a magnetic indicator base on the barrel and indicated to the forearm for less than .002" deflection from snug too tightened on the action bolts.
