Gunsmithing Too much material from action/bolt?

[flyfisherman246]

I have a 700 action/bolt that has been through a couple different smiths hands who all didn't trust the guy before and "retrued" it. Most of the primary extraction is gone due to the bolt handle being so far back. Other than having the bolt handle timed, is there a point we're there has been too much material taken from the action lugs, bolt lugs, and bolt face? How would this be determined? Is there any potential for a safety issue?

What size are the barrel tenon threads now?

It's still only opened up to 1.075" on the action, I'm just worried too much has been taken off the lugs or bolt face. Other than loosing extraction with the handle, is there anything to be worried about?

Thanks

Eventually the lower lug in the receiver will get too thin, start doing some extra flex during firing, and either it will crack over time, fail abruptly, or the extra load placed on the top lug while the bottom one flexes will damage the bolt.

Good luck finding someone who can/will tell you how much is too much.

The action lugs seem to have plenty of meat on them, most of The material was removed from the bolt lugs. Within reason, is there anything that can really fail on the bolt itself if material was removed from the front and back of the lugs, the bolt face, and the bolt nose?

There is about a .045" gap between the back of the receiver and the front of the bolt handle.

From front of the bolt lug to back is .419"

The bolt face was cut about .0105" from original surface.


Anything To be concerned over once the handle is re timed?

I completely agree, if it's at all dangerous, it's a no go. That's what I'm asking about. When you loose a total of .020" material from the bolt lugs when your starting with .440, does that mean anything at all? I see no reason to throw out a bolt and action if it has the equivilent of a scratch on it relative to the overall strength of it. Am I worrying over nothing?

A new bolt from PT&G would be a relatively inexpensive way to be certain your bolt won't fail.

It's likely fine from the standpoint of not exploding during normal use.

As for the PE, I have a solution. It'll require us having the bolt/receiver as the bare minimum. Here's a link:
