scope mounting screws?

[vetter3006]

What type of threadlocker do you use to apply to the scope mount screws, red is high strengh or blue is medium strengh? I never used threadlocker on these screws before but now shooting my new 300 wsm am finding that they loosened on me and want to apply some next and tighten to spec and see if this helps.

The Blue is the standard for firearm screws.
Only use it on the base screws, not the ring screws.

Red is usually used when you don't want the screw to ever come out. Blue is used when you want to hold the screw tight and still want to be able to get it off someday. I'd also reccomend Blue for any gun use
