Remington 40X vs. Tuned Remington 700

[Scarface26]

Probably too late, to respond to this, but I have both a 40X and 700 in .308. The 40X is a work of art. The 40X bolt is noticeably heavier than the 700 bolt. I don't know if that's due to higher quality steel in the old 40 X vs. the 2008 vintage 700. The 40X will put five shots into an inch at 150 yards with iron sights. The 700 will not do that with a 10X scope. It is a 1min gun, no better, BUT, in fairness, it hasn't had the level of smithing that my 40X has.
Also, the 40X is clip-slotted which is a nice thing to have on a repeater.

Finally, my 40X i(XC) s for sale. Message me if interested.

Wonder whats different about your 40x bolt over a 700?

 

[Scarface26]

The only thing I can think of that might be different between the 700 bolt and the 40X bolt is metallurgy. Perhaps the steel that Remington used before I was born is more dense than the steel now. The difference in bolts was a surprise to me. Can't imagine that there are components internal to the bolts that weigh that much differently. Both of my rifles are fantastic, but the 40 X allegedly comes from the custom shop with a lot of smithing already done on it that my $500 model 700 just didn't get.

What I know could fit on the back of an envelope.

The old bolts had steel shrouds and the newer one are aluminum.

At the risk of starting another flame war, if one does research, you will find that although the 40 xb/xbbr receiver is made on different production runs with a few minor differences than the 700....the only "smithing" done in the Custom Shop is fitting the button rifled , lapped barrel to the action and bedding the action to the stock. If the Remington craftsman do any "truing" to the action it is sub-par work as numerous reputable renowned smiths have claimed every 40 xb/xbbr they had worked on had uneven lug engagement and the bolt face usually was not true. This is despite Remingtons claim that their 40xb/ xbbr are blueprinted. The fact that their accuracy guarantee is now 0.45" for 5-shot groups @100 yds for calibers < .30 and .75 " for .30 cal. is very telling. I have shot BR for 13 years and the only 40xb's I have competed against have all been trued since they left the factory.

Back in the day, I read an article that described the differences between ordinary 40x CF rifles and 40XB-BRs. Some years later, after Remington's move to the sun belt, I called up the custom shop and spoke with its manager to confirm that those differences were the same. He had no idea what I was talking about. Some time after that, 700 clones came into being, both single shot and with magazine cuts. I would wager that just about any of them are more true than any untouched 40X.

They are all good til you miss or throw a flyer.

South Pender, what does lapping the lugs accomplish?

It gets both (or more than two) lugs in full contact with the lug recesses, thus ensuring that each lug bears its share of the thrust on firing.

Lapping lugs tells me something-
The 'plumber that did the molesting of the bolt lugs was not quite sure of his/her set-up while facing & uses lapping of lugs as confirmation of the set up.

 

[BoydAllen]

Proper correction of lug contact is done on a lathe. The only lapping should be very slight, for final finish. There is a lot of old info out there that can lead you astray if you want the best results.

south pender, it is useless to lap the lugs on a bolt that is not fitted to the bolt bore of your receiver. The upper lug is pushec away during cocking by the cocking piece. The most perfectly machined bolt and receiver will not touch on the upper lug until after firing, unless you have purchased a custom fitted bolt or bushed the OD of your factory bolt.

Was that sentence long enough?

yes and you are right , if you can push down on the cocking piece you have a lug problem

and it take a lot of pressure to push it down if you want to test this

Takes more then an action to make an accurate rifle.

 

[Liven The Dream]

I have 4 700 SA Fully Tuned .
2 Single Shoot 2 With Glue adapters to Sigle Shot .
No Real Difference .
But one CM with Glue in Adapter is my go to !
Just is ?

This is a seven year old thread.

This is a seven year old thread.

True, but it’s an argument about the accuracy potential of a single shot versus a repeater, so by definition, that makes it ok. I’m pretty sure there’s a rule that the single shot/repeater argument MUST OCCUR AT LEAST ONCE PER YEAR.

 

[rkittine]

I have trued 700s, Stock 40X and Worked 40X actions, and then there are my Borden Actions. I can have terrible scores with any of them.

 

[joshb]

I have a couple of each....not a lick of difference.

He said “lick”. Old school! I love it! Happy 2015! Wish I bought more primers back then! Like 100 thousand!

This thread is so old even Dusty's avatar has gray hair on his beak! LOL!!
