Remington 40X vs. Tuned Remington 700

[South Pender]

I know 40X actions are prized (I have a 40XBR in .22 BR and love it), but I've often wondered whether they are superior to a carefully-tuned 700 action. To make the comparison reasonable, let's say that we have Jewell triggers on both. The 700 has been "blueprinted" or trued, and both rifles have identical barrels. Is there still a difference in favor of the 40X?

 

[fredhorace77]

No difference. Actually a blue printed 700 is at an advantage to a stock 40x.

Truthfully the solid bottom of the 40x is a good thing however the 40x from the factory isn't trued as well as the 700 so I would say if they are bedded correctly all things being equal the 700 in its present configuration is or can be more accurate than the 40x.

Delete this ridiculous BS!

I THINK DAN40X IS FIRED UP BUT IN MY SHOP THERE NO DIFFERENCE FRIEND!!!!!!!!!!!!

Of all things to argue about, lol geez

 

[jonbearman]

I wasn't the one who started any argument, it seems that you are not allowed to express your opinion anymore. By the way I was speaking of the original posters 700 he just had trued not all 700's.

 

[Alex Wheeler]

There will be no accuracy difference. I have not seen an accuracy difference between a single shot and repeater.

 

[22DASHER]

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

Along this line of discussion, sort of, for those of us without access to a good local gunsmith, are there any good recommendations for a good smith with fast turnaround that is not one of the large widely known ones. In other words someone reliable and capable yet small enough to talk to.

Gre Tan Rifles! Fantastic work, quick turn-around times. Greg is great to work with.

And have seen and understand the enhanced advantages that trueing and timing of an action has to functionality, smoothness, alignments, and accuracy potential.

Please excuse my ignorance here, but what exactly is involved in "timing" an action. I get truing--getting the action and barrel perfectly in line by truing the barrel/action threads and getting the locking lugs lapped and bearing evenly--but where does timing come in?

 

[Preacher]

Timing has a lot to do with primary extraction being set perfect......
Primary extraction, when correct will be a huge help in extracting a tight case in the chamber...
When primary extraction is off, (99% of factory 700's and the others are off a lot ) you will not have any help in removing a tight case, and usually you will hear a CLICK when the bolt handle hits the side of the action and leaves marks on both surfaces it contacts, instead of both surfaces meeting at the same time like they should, and camming the case out of the chamber.......

This reads cheap. Do you wonder why the good smiths are behind? South Pender, what does lapping the lugs accomplish?

That video is demonstrating it wrong. He is pulling the lugs back against the closing cams, the cams should not touch as he wants them to. To figure how much extraction you have you must lift the bolt handle straight up until it contacts the cam and is forced back, the amount its forced back is your primary extraction.

I know this is just a clone of a 700 but are the stiller predator actions timed right from the shop?

Not trying to hijack the thread, was reading it and was wondering.

Thanks T 700

There are two kinds of timing usually discussed when it comes to actions. One is bolt handle or extraction timing the other is ignition timing. When timing a bolt handle you are installing it so in the close position the lugs are at 6 and 12 o clock, and in the open position the cocking ramp is aligned with the cocking piece slot in the action. You also want the bolt handle close to the rear ring of the action to make the most use of your primary cam. The cam on the bolt should follow the cam on the action too far counter clockwise (looking at the rear of the bolt) and the cams will bind, too far clockwise and the cams wont come into use.
Ignition timing has to do with the cocking piece handoff to the trigger and the cocking ramp in the bolt. Most every action has this problem, you close the bolt, the cocking piece rides down the cocking ramp until it is stopped by the top lever of the trigger, then the bolt body is pulled forward by the closing cams. A timed action goes like this, you close the bolt, the cocking piece contacts the trigger at the same time the lugs come off the closing cams, no fall to the trigger and no cock on close. Then when you open the bolt the cocking piece ride up the ramp until the trigger resets, in an untimed action the cocking piece continues up the ramp to the notch adding to extraction effort. On a timed action the cocking piece stops at the point of trigger reset, no extra cocking effort during the extraction period. I hope I put that in words well enough to understand. Its really a simple subject but it is hard to explain in print.

Nicely said Alex, could not have said it better myself. It can be a topic that is not all ways understood by clients in my experience, but understood after alterations have been made, some small some large.
