Thread: Kimber Hunter .280 Ackley Improved

Ah but you see @Sideshow the polymer or alloy material over time gradually compresses and flows up into the gap between the action screw and the pillar. Makes it a pain in the rear end to remove the screws and if it gets brittle it will snap and you're left with too big a hole for the screw. Mine didn't get that bad but I've seen it happen on another pillar bedded Tikka. The fault isn't the torque so much as the cheap-ass materials used for the bottom "metal".

I found sticking to 40in-lb with epoxy bedded rifles with pillars is fine. I only use 50in-lb on my chassis based rifles.

Another consideration is that if you torque up some of these lighter actions too much, even with bedding, e.g. T3, they will twist ever so slightly and even as much as not being able to turn the bolt. I have a T3 Laminate stock here with a proper epoxy bedding job plus pillars and no way will the action take 60in-lb. I tried!

And the DPT chassis on the same action at 60in-lbs produces the same results, but is fine at 50...
