Okay guys heres the bread and butter of my plan. I have a savage 111 chambered in 300 win mag. I have the chance to buy barrel and bolt face off a savage 111 LR Hunter in 338 lapua. Is there any reason other then shank diameter why I cant change the bolt face on my 300 (0.550) to that of the lapua (0.585), have the barrel threaded down for the small shank action, screw it on, check headspace and have a lapua for under $500? Or am I dreaming and need to snap out of it. Any help is greatly appreciated.
 
If you want a LM just to impress your friends, you're in.

If you realy want to get what the cartridge is capable of, go with a single shot action built for that round like a stiller tac 338 or similar and spin a 32" idaho contour on it.

If you realy want a repeater, a sako M995 is probably the best option
 
I'm not sure that I would want to reduce the diameter of the barrel around the chamber, probably why Savage built them on the large shank to start with. I have a Savage 110 FCP 338 Lapua and though it is not up to dero338's standards it shoots quite well for the money which is much less than any of the options listed above.
 
The way the Lapua round really performs is in an action actually designed for it with a 28 inch barrel or longer ... forget Savages and Remington.

If I stick a 30'' barrel on a remington what's wrong with that?

I dont see how a different action will make it better than a savage or a remington.

338 Lapua's are generally built on a larger, heavier action than the Savage or Remington. The PGW Timberwolf has a 26 inch barrel and the Accuracy International AWSM (L115A3) has a 27 inch barrel and these are two of the most accurate 338 Lapua rifles commercially made. If you are looking for a bench only range gun the long barrels offer a bit more velocity at the cost of unwieldy length and extra weight.

A 700 will handle a 30 inch barrel no problem. It's the cartridge that is not well suited for the action. Remington should have made a new 700 action scaled larger in all dimensions for the big Lapua... they blew it...

Savage and Remington never made an action specific for that large cartridge as other manufacturers have. They crammed it into regular actions... actions that will not handle the hot loads as large custom actions will... Remington and Savage will develop hard extraction way before the custom actions made for the big case will.
 
I have a Defiance Rebel on my .338 IA. It is the same OD as a factory remington. I ordered it with the extended tenon to support the weight of the 31" barrel and I went with a full 1.350 diameter barrel. The action only sees the back pressure. The barrel contains everything else. I don't have any concerns with mine. Shoots great.
 
I'm rebuilding my 338 lapua ai right now.

This time, 30'' barrel with a brake. It's a Remington MLR that started it's life as a 338 lapua.

Im going to go with a Jury barrel, just trying to decide on barrel contour right now.

An action that the round actually and really fits in will make life much easier. the Remington and Savage just don't cut it, which is why no one uses them. If you have your heart set on a Remington then a 338 Edge would suit you better.

I built a 338 Edge a few years sgo off a 375 RUM donor. Went with a sendero barrel contour, 28'' and a Defensive Edge brake from Shawn Carlock.
Used my factory Remington MLR bottom metal and magazie. Feeds really well. The 338 lapua ai doesnt seem to feed worth beans out of that magazine setup.
 
It's funny how Remington actions are considered fine for 338 Ultra Mag and not at all for the 338 Lapua when the only difference is that the 338 Lapua is a whole 0.036" wider above the rim and actually shorter and acoording to most sources runs at a lower pressure, the Ultra Mag at 65,000 psi (450 MPa) and the Lapua at 420 MPa (60,915 psi).
 
Just a question,
Would SAAMI reduced the Operating pressure of the 338 LM just after Remington started to make them?

Actions made for the LM have a bigger bolt,bigger lugs, larger diameter and longer tenon

Is it possible to tow a 10000 # fifthwheel with a F150?

Yes but its a lot better to use a 250.

The difference in case head diameter is much more significant. That's part of where the Remington sucks...not much meat left to support the extractor with a M700 bolt wrapping it's lips around a Lapua case head.

Yah, but does Ford sell a 10,000lb fifthwheel from the factory with an F150?

Remington sells a 338 Lapua from the factory.

You'd think if these big companies are willing to sell these products brand new, they must have been tested
to be safe or else they have their lawyers on stand-by.

The reason a Lapua gets by in a 700 is the strength of the brass... it will show signs of pressure and be hard to extract long before case failure... and at lower loads than a larger and more robust action will handle.

I feel Remington really blew a chance to build a new Magnum 700 ... by simply scaling their present 700 up in all dimensions keeping the enclosed extractor design. It would have been a superb action for all those big cases.
 
I guess a bigger stronger action is always a good thing and the Remington and Savage may be at minimum size for the 338 Lapua cartridge but they handle it just fine. If there had been any failures anywhere in the world in these rifles in this caliber it would have been plastered all over CGN by now, many years after their introductions all is fine.
Like I said earlier I have a Savage 110 FCP in 338 Lapua and it handles all loads I have tried with 250 to 300 grain bullets all up to book maximums with a few different powders with no pressure problems. I do use Lapua brass which was designed to handle the pressure the cartridge generates in all rifles.

From: http://www.lapua.com/en/story-of--338-lapua-magnum.html

Also the interior structure of the case was redesigned to withstand higher chamber pressures than the original, designed for rarely low pressures, modification of the .416 Rigby could have withstood. So, the .338 Lapua Magnum was in fact a new Finnish cartridge, even though the idea was born at the new continent.

The reason for .416 Rigby case being a good prototype and parent case, but not the actual choice for the new caliber case was quite clear. For the .338/416 cartridge the velocity of a 16,2 g bullet was 915m/s. A completely different case designed for a higher pressure level was clearly needed. The original Rigby .416 case had a rough 3000 Bar pressure case. The new cartridge was designed for over 4000 Bar pressures.
 
Not enough meat behind the lower recoil lug and in a regular long action it will bend down. Savage changed this when they made the Lapua in a BA. They also missed an opportunity to make a better action for it. The strength of the brass is what is saving the shooter not these two rifles! I built them before Savage did and at the same time or before Remington released theirs.

OP, if you want to do something with that action, check out the 338 RUM. If you want a Lapua then sell that and get a Lapua action at least.
