Re: question on wearing out an action?????
I would think Krieger would be forthright and tell you if it's not workable. They stand nothing to gain from poor quality results.
The 700 action is pretty durable and can withstand a little abuse. But, it's not impervious either.
That said, you'd be looking for such things as:
- anything that might indicate structural weaknesses such as chips or cracks in the wrong places
- excessive rust or pitting
- gualing of the bolt lugs (a little could be cleaned up)
- ditto for the lugs inside the receiver (once you have the barrel off)
- pitting on the bolt face and signs of gas leaks around the primer
- signs of alterations, such as messing with the sear
- if it's never been rebarreled, then the receiver threads should be fine
Most of these issues can be cleaned up and/or replaced. But, the question at some point becomes whether or not you would just want to keep your grandpa's old 700 in tact and start fresh.
True/time and reblue the action
Replace whatever bolt parts need replacing e.g. firing pin, springs...
Pillar bed in a good stock
Aftermarket trigger, setup correctly
20 MOA picatinny base, rings, good optics, sling, bipod, range finder
and a sharp knife
That's my $.02.
