Typo? Do you mean factory tube?
No, I do mean factory action. Alot of the performance you hear about are from rifles like the SAKO, AI and customs. All have nice tight lock ups that allow for warm to toasty loads to be used without serious case expansion issues.
A typical Rem 700 has a bunch of issues from moderate/poor lug contact, misalignment with bolt face/chamber and raceways,etc. All the little things that a smith blueprints out when a factory action becomes a 'custom'.
All they are doing is making the lock up straight and tight. Then there is also the issue of chamber dimension of which I have no idea what is in the Rem.
A combination of high tolerance in the action/chamber coupled with any bolt movement during firing will cause cases to bulge at elevated pressure.
The 'pressure signs' commonly quoted show up in this type of rifle.
So, that will limit how much pressure/how fast you can push any bullet.
The barrel only affect on speed/pressure is in bore size/roughness and length. Hopefully, these barrels will shoot accurately when fired fast.
Otherwise, you may have a rifle that performs no better then a 338 RUM.
As to building a 338 LM, just depends on the bells and whistles but even if it is a bit more dollars, you end up with a purpose built rig that will shoot more accurately, most likely at desired velocities with reduced recoil.
If Savage announced a 338LM bolt head in the near future, building one for what a Factory Rem costs now is very possible. If single shot, even less money.

Interesting about the 700P .338 Lapua
Thin bolt head, AR-15 type extractor. I guess my Sako extractor modded bolts have been safe all along according to new Rem policy. If we customize it, it's dangerous, if the factory does it, it's safe. LOL
Of course you could argue these new modded bolts are not safe, but then we'll have to wait for one to blow up or one of the thousands of Sako mods.

A huge difference between a Sako extractor conversion and what Remington and others have done with this conversion. Not a fair comparison at all... Nothing safe about the Sako conversions if there is a catastrophic case failure. You don't have to wait for a Sako conversion to blow up... That has been documented ... one death and some serious injuries reported on Benchrest Central a few years ago. Sako extractor into the brain...
I think the safety issue, while valid, is over-blown. Remington, you would have to assume, would have been especially deligent in this area given the well documented concerns of those who are "in the know".
In the end, Remington obviously feels the risk can be well "managed" or this rifle never would have made it to market.
I think the rifles is worthed for the money since a sako extractor type was put in and muzzle break was installed by a professional, but as for the prices, that is a pretty good deal, other wise build you self a 338rum, and the outcome would have cost bit more, as for the barrel length, it would be nicer if the barrel was 26"...I don't see what so unsafe about opening up an existent magnum bolt face to accommodate the 338Lapua, it been done many time already by gunsmith. and as for previous gun that had blow up, faulty cartridge had lot to do with it in my opinion...

Actually Glock, you should give ''####'' some slack here..I know him personally & he's good to go.
While bedding a couple of Remington 338s today, I noticed Remington went with #8 screw to hold the scope base on which was a change and they also added side screw holes for a side mounting open site system but no holes in the barrel for a front site. I'm not sure what that's all about but whatever. Working up load developement should be entertaining. Best of luck to everyone. Don't start any grassfires.
Rem brass flash hold is not drill out like Lapua, but I had around 3 to 4 load already on my rem700PSS 300RUM, it good to go, no problem here, and still get nickel size at 100meter, and not that I spend that much time with 300RUM any way, but then again I am not trying to sell rem brass Either...
People that reload for accuracy typically weigh their brass for consistency and a lot of us have found out the Remington's brass just isn't consistent in weight. That's probably one of the top reason's for variation in velocities and pressure. The outside of the brass is a constent but the inside can vary in thickness all over the place.
Gunboy, given that your load developement went well at 100yds, what's it doing at 300-400yds. That's far more important with any load unless you're use to shooting stuff with your 300RUM at 100yds...

This has been my experince as well.
Up until Nosler started to distribute 300 RUM brass I felt the caliber had missed the boat. The potential of the cartridge was defeated by the crap Remington offered for brass.
As busy as I am, to waste hours trying to match prep Remington brass was just not worth the effort.
The 338 Edge rivals the 338 Lapua ballisticly, so with Nosler brass it stands a reasonable chance of matching what the 338 Lapua can do.
The Lapua brass is still a step up.
Still looking more at these 700s, they should make for a reasonable platform to build real rifles on.
