I have a tikka ctr that I have had the action screw come loose before.
I put this into a Mcmillan Stock torqued to about 40lbs and they came lose over the weekend hunting do I need to try a little loctite to help or more torque.
Stock is new

I would be carefull adding more torque than what you have. Some other users have had issues when going over, maybe they will respond.
I would try some locktight before I really strapped on them, you don't want to overdo it. Torque on action screws depends a lot on what kind of bedding you have. Wood or synthetic no pillar bedded I think 30-40 is what most manufacturers recommend.

Loctite is fine. Use the low-strength stuff (blue I think).
40 in-lbs should be fine. Since the CTR has actual metal as the bottom metal, more torque would probably be OK, but I wouldn't personally go past 50 in-lbs. And Loctite will do a better job keeping it secure than more torque will anyway. The Tikka action screws use a pretty big torx bit, so the low-strength Loctite would be totally fine.
I torqued my Tikka Varmint rifle to 55 in-lbs and found out that my action screws were preventing my bolt from closing because the plastic bottom metal had somewhat given way. The CTR shouldn't have that same issue, but there's no reason to go past 40 or 50 anyway IMHO.

How many rounds fired before you noticed they were lose? I have a tikka ctr that I have had the action screw come lose before.

3 rounds makes me wonder if something else is up. I would retorque and try again. If it comes loose again I would maybe consult the stock manufacturer. Did it do it before you replaced the stock?

Odd that it has happened on both the Tikka and McMillan stocks. Are these the original screws that came with the rifle? Without the stock, do the screws seem to thread properly into the action? I would suggest cleaning/degreasing the action and screw threads thoroughly and torque to specs with red BLUE loctite. Threadlockers will not cure properly with oil residue on the threads. If it comes loose again there is something else going on.

I'd use blue if any at all. Maybe even purple.

Maybe you meant blue? Yes, thanks for catching that! Red can be removed but heat is required. Use BLUE for this application.
