First Remington 700 build. Do nothing at all, true the face or full blueprint?

Assuming Vintage Sniper is shot with a sling,

I've heard of those things...

If you are doing it for the experience and to be able to do it for your customers, do it all. This one might not need it but you can learn the steps checking to see if it does. You are doing it right learning on your own stuff. You certainly don't want to screw up a customers gun! Good luck on your business.

The bolt handle seems to be in the right place for good primary extraction. There's maybe a 0.005" gap between the front of the bolt handle and the handle cutout when it's fully closed.

On the later receivers with the 'long tube' bolts, using the front edge gap as an indicator of the amount of primary extraction can be misleading. Take a good look at the cam angles and see how much you really have working for you. It's not unusual for the handle to need rotating.

Removing the firing pin assy and pulling the bolt handle back so the lugs are tight against the lug abuttments as the bolt is rotated as you watch the bolt handle come up on the receiver cam angle....works pretty good for eyeballing this.

I'm not a 'smith or machinist...just a hacker. But that's a pretty good approach if you're new to 700's.

Good shootin' -Al

Al is dead on. I have seen a number of bolts where the front gap is fine, but the tail of the handle will contact the lug way before the extraction cams touch. Just shortening the tail to allow more rotation let the lugs engage again with their back side. Now try to extract that! The handle needed to be rotated and shortened.

M40 Clone, I assume it's for the vintage sniper matches. I think I've built 10 so far, lots of first place tickets. I true the face and pin a recoil lug always.

I've got a couple coming back for a full bolt sleeve. That reminds me. I really need to get into bolt handle work.

What do you mean by full bolt sleeve?

 

[LVLAaron]

Sleeve the whole body, not just two points.

 

[philip brousseau]

Do you bore the receiver and sleeve the bolt a certain diameter? Do you cam front and rear for zero bolt movement when the bolt is closed?

 

[philip brousseau]

What I'm getting at is bolt binding a problem?

 

[LVLAaron]

Depends on the action.

 

[LVLAaron]

Here's a stiller bolt I did. The action was straight and true, but the bolt was 8-10 thou undersized and I wanted a better fit.

I know a guy, one of the most prolific competition shooters in history, that said that improving bolt slop was the only "action truing" that he actually saw groups get smaller.

 

[LVLAaron]

I'd argue if you're only going to do one thing, it should be to true the lugs. Can't tell you how many 3 lug actions I've seen that only contact on 1.5-2 lugs

I’d also say take a cut on the front ring to true the face of the receiver. Talking Remington here. RR and RAR’s might be the exception but I’d still check them.

I would REALLY like to see someone do a TEST of all this "truing" and see if it shows up on a target. I think that would be a GREAT test. If the test were done in a valid way.

They definitely need it, but if it came down to that or lugs, I'd choose lugs.

Cortina kinda tried with the 6.5 Needsmore series.

But if you've set the action up to true the lug abutments there's no reason to not check and cut (if needed) the face. It's one setup.

The point is; we were picking ONE thing to do. Not what things are easy. And sometimes getting the lugs right doesn't need a lathe

Sleeve the whole body, not just two points.

I have not sleeved one yet,
thinking about it, planning ahead on it
wouldn't sleeving the whole body be the better way to go?
