Gunsmithing Another rem 700 action question

[skeetlee]

I have noticed on one of my rem 700 that i have had blueprinted that after a dry fire the bolt seems a little stiff to open. On my factory rem 700's this isn't the case. Is this a good thing? I know the man that did the work is good to go so i am not to worried, just curious i guess. Like I said the bolt just seems to have some resistance after firing on an empty chamber. Bolt throw down is as smooth as can be!! Just on the way back up after the hammer has fallen??? Any thoughts?? Lee

My guess .... the cocking piece, where it rides in the bolt body, needs some lube.

Bolt needs to be cleaned up. It surprising how little it takes to make a bolt stiff.

My answer is going to be... Maybe the way the extractor is working on the upswing of the bolt? check the brass for marks on the rim?

Re: Another rem 700 action question

I made the EXACT same observation when I recently received my first custom using a Rem 700.

Like yours, mine was only a little tough when cocking the FP--in other words, only when re-setting the FP to fire.

When mine was built, I added the gre-tan firing pin and shroud. My guess is that mine is a little tougher b/c maybe the GT FP is a little stiffer than the stock one--but that is only a guess.

Did you alter the FP or FP spring?

This is the first place I would check... also...I've seen the firing pin body get hung up in the shroud because of a nick or burr or built up corrosion. Clean and lube these areas first.

Here is an m700 firing pin with a couple of nicks on the firing pin body that were hanging up in the shroud. It's a tight fit and doesn't take much to hang up.

Ding ding ding!! We have a winner! Same issue as my Gre-tan. I do not think it is anything of which to be concerned. I think it is just a slightly stiffer spring.

Just for grins, if you have your old FP assembly, throw it in the bolt and see if the stiff bolt goes away.
