Remmington 700 bolt lugs

[6MMsteve]

Have 2 RR prefix 700 actions with bolts, Are the lugs offset on the bolt, being the abuts are offset also or is that the way it is? I took a red sharpie and the bottom lug touches well but the longer lug does not touch at the top, ok let me explain pick up the bolt look at it 1 lug looks .040 farther toward the bolt handle than the other, I thought I was seeing things till I took out the other bolt, I'm confused thinking about just lapping them, I ordered a tool for lapping, need some guidance I don't want to get involved in having a gunsmith true it just kinda wanna play with it, these are remage so headspace is not a issue

Use a depth mic and measure from the receiver face to both lug abutments and then on the bolt. Even the long end of calipers would be close enough to tell if it way out like that. What I interpret you question to be, makes no sense or something is bad wrong. At least I've never seen offset lugs on anything, especially not a 700.

If its .040 different that is real bad. That action may have been overpressured and need to be really looked at

Gonna have to do some actual measuring and photos for this one .

True, but if you remove 40 thou from a lug, you're not going to have any extraction... and other timing problems.

I usually don't make sense lol, they just look funny as in funny way off but I have a depth mic may do some micn, thanks

true that I think I will stop before I have to go gunsmith calling, just shoot it..thanks I almost made a mess

 

[6MMsteve]

I had all my questions answered, don't mess with it

The abutments were at +- .002 across at 4 points, I may lap a small amount, I need a Ht gauge to chk the boltlugs, have a surface plate and need a jig, but will do a light lapp with 600 grit compounds

I don't understand how an overpressure event might have caused this. Would you mind explaining it a bit? I'm confused.

I don't know the abutments are good, it's a new action maybe 20 shots with factory ammo, I think it's my eyes I'm blinder than a bat

Every overpressure ive seen, like the short mags in a model 7, always set the bottom lug face back and usually cracks it next to the loading ramp on each side. Ive posted pics on here before. This isnt your popping primer type events, this is counterbore swelled and brass swaged in type stuff

If you have a depth mic, measure from the bolt nose to the front of each lug. Should be about .150. Now use a mic or calipers and measure the thickness of each lug and add that to your previous measurements. It won't give you a precise location, but it will find any gross errors like you're describing.

I think it may be the way I'm looking at it, without measuring I don't know

yep one side was at .149 the other side .147

I concur

 

[6MMsteve]

Lug length to bolt body .446 and .443..seeing things I was

thanks for your help, I appreciate it and only a couple thou in difference on all the areas you told me to measure.
thank you
