.338 lapua improved on ti action

I like the look of the lone peak for sure. Pierce's new website is not very good that's for sure no real specs. But I have one and I do like it. They did the whole rifle and it really does shoot. Plus they have access to the reamer used for my other ones. And to make it better they are only an hour from me.
Not saying I'm not willing to go elsewhere as if a better product exists then of course. But if the pierce action is build to the same spec as the lone peak .338. Then it would be safe. I'm looking mainly at safety. So if lone peaks is built for it than a 700 footprint can be safe. Just wonder if the pierce is the same as doesn't seem to be much different in the .338 lone peak from the standard ti. Maybe tenon?
Recoil on this may be rough but lighter Bullets and a brake from Kirby should calm it down to manageable levels.

Check out Mesa Precision Crux Ti Lapua actions, I'm using one for my 300 Norma mag.
It weighs 22oz, I got mine for $1100.
If you're going to shoot lighter bullets why not just build a 30 cal and shoot 225's or 230's?
I know you're set with 338 brass, but in the scheme of things buying dies and 100 cases for another chambering is nothing..

My Lapua is built on Deviant Hunter.

They have a .590 bolt for this action. I have several buddy's with 300 Norma's and a 338 lapua built on the Deviant, which is close to the same action but less of the rail has been milled off and it weighs a little more.

That is the action I was referring to but you can build a 338 Lapua on the deviant ultra light as well. It's basically the same action. They use the .750 Bolt with the larger lugs. I just called and confirmed this with defiance as I've been trying to decide which receiver to use myself. I noticed their website has been updated and is much more informative now. They also have the option to make this a controlled round feed if you like.

I wouldn't consider any action that has a 1.062" tenon thread suitable for a 338 Lapua sized cartridge.

Its nice working with company close by.I live about 300 yrds from Defiance,and know a guy that works there that use to guide,so thats where I go

I'm not stuck on light weight only for here in Michigan where I have to try and get to 500 yards. When I go to Africa or Texas I like to walk a lot so the weight would be nice to keep light. In those cases I'd like to shoot 300gr.

There are three main things I look for in a good candidate for a Lapua class chamberings.
Larger than .700 bolt diameter, I want a flat or coned bolt nose, and larger than 1.062 tenon.
Titanium stretches much more than steel and even in smaller cals we see bolt lift sooner than a steel and even in steel actions you'll feel bolt lift sooner in some than others bases on material and heat treat. I would be very suspect of a 1.350 diameter Ti action for a Lapua class case simple based on how elastic Ti is, and putting larger threads than 1.063 in a 1.350 body that's Ti and it's going to be a compromise.
I see issues regularly with RUM class cases setting back lugs and tenon movement in a Rem size action, a Lapua just magnifies all the issues. I see a couple makes of high end factory rifle come in frequently for poor extraction of Lapua cases because they just can't handle the full capability of the Lapua case so I polish the chamber and do the best I can so they can at least function at a lower level but it's obvious that just because it doesn't blow up does not mean it works good!!!

So I was in contact with both lone peak and pierce. The lone peak to .338 only has a bigger bolt than the standard also. Pierce runs a 18 tennon and lone peak does 20.
The standard aftermarket action run a 16.
So pierce kinda split the difference. He stated they have run several.338 lapua off it with no issues. He also said he would do the 20 Tpi tennon if I would like. They both seem very confident in running the lapua in this action. But I'm not dismissing all the feedback that's why I'm still hesitating.

Call Jim Borden, he has a full understanding of metallurgy and is one of the few action makers who are not just machinist who use the "haven't had any problems" method of testing material and design.
Dan Lilja also has written on the issues with Lapua class cases on such actions.

So reading over this thread what about the factory Remington that are 338LM. I dont know if that is considered a 700 action but I have read it is actually larger than the 700 action. So would that one be ok for the 338 improved?

From what I understand it's weaker than the aftermarket actions. Which is kinda the point of the thread. I know they work like the guys building on a savage long action. It works but I don't want to be the guy who has one go pop. I'm not a huge fan of my face but I like it enough to not wanna make it worse.

More of a RUM vs Lapua write up, but here's what Borden says.

It's a standard size Rem 700. There are rumors that it was heat treated differently but who knows if that's true.
