I have a FCP-K in .308 which has an action that is .020 thou. out of alignment from front to the back due to the heat treatment in production(it's just in spec's) but it's the rear section which is lower, which means I have to shim the front of the action(have done this) & scope mount to "true it" so to speak, shoots great, but, the question is.
Can I use a bit of force with vices, blocks & bars to re-twist the action straight?? Or is the action not up to a bit of pushing or pulling to straightening it?? The shims just plain out annoy me.

Thanks Geoff
