.338 Lapua Mag Build

Gold $$ Contributor
Looking for input on a 338 LM build. Action and barrel recommendations. Would like to keep the barrel length at 28" max. Heavy varmint taper. I have a large supply of 250grs.
Planning on an A-5 or similar stock. Going for a tactical look.

Thanks for any input.

Look at any of these companies they make great actions. The 700 will take work so I would avoid it.

Actually, that blog is not a particularly good lead as none of the competitors addressed in that blog are shooting a 338, much less a 338 LM - see http://precisionrifleblog.com/2014/10/14/rifle-calibers-what-the-pros-use/

That noted, some of those companies do also build excellent 338 LM-capable hardware.

You have a lot of options - see my rifle components page - http://elr-resources.com/page3.html

Note that Manners also builds excellent stocks and XLR builds excellent chassis (both offer solutions that avoid you needing to deal with bedding). McMillan provides no such option.

Availability may seem an issue but you'd be surprised what is out there - if you just make a choice of which brands you want and folks can point you the way.

In any case, enjoy the build and great shooting!

It is far better than you give it credit for. If you were not so focused on self-promotion you could see that.

I figured I did not need to point out that the website I referenced was short actions and the OP needed an action for a 338 LM apparently not. So I will state it. A company that makes a great short action would put the same level of precision into larger actions to keep their good name.
 
In building a Lapua because of the diameter of the round I would not build on a REM or any action that don't allow a bigger tenon. I feel with the size of the case you need a bigger tenon and bolt diameter. Not only to be stiff enough to shoot good but also the safety factor. There is a lot of bolt thrust with the big cases. Matt
 
I have debated this many times. The Weatherby mk 5 action has a tenon of 1.06 and chambers the 460 Weatherby mag . Which is Larger than the Lapua (460 WM)
Now please don't jump all over me . I have chambered a few 338 Lapuas on std Savage 1.06 . These have been for myself. I do use 41v50 steel . I have fired factory , reload s , and after checking headspace,and confirming all good , shot many , many loads . PM me as I would not recommend this for everyone. I just paid my liability ins. Even though I've been retired many years. Check out the Weatherby specs . I used a modified barrel nut on one rifle and no nut on the other .
 
The Weatherby Mark 5 has a big enough bolt. But the small tenon will yield under pressures and if you would get a case head rupture it wouldn't be pretty. The 460 Weatherby has a 64,000 pressure spec and the 338 Lapua has a 68,100 pressure spec. The Lapua is also bigger in the base of the case by .005. Almost no gunsmith will chamber one in a REM or small tenon action. Almost all want a Stiller Tac 338 or bigger action. I just know I wouldn't do it. Matt
 
I have a defiance machine devient action with an extended tenon on mine... fluted swirl bolt, over size bolt knob... kreiger barrel finiahed at 29inches as a brake after that from ross schulers partner... the barrel is a custom contour i wanted... 1.35 for 6 inches then down to 1inch. Its heavy.. manners t4a stock in gap camo... jewell trigger... its about as good as it gets...

What size bolt and tenon does Remington use on there factory 700 338 Lapua?

everyone i know thats had a remeington 338 said it shoots like shit... i hate to say it because i hate savage.. but the savages ive seen shoot just as good or better than a custom rifle... my bro in law did a sub 3 inch 5 shot group at 1000 yards the other day with his factory savage 338... i wouldnt beleive it if i didnt know him as well as i do amd seen the pictures..
 
My advice , go longer on the barrel 31 - 33 " . Cant go wrong with a barlien . Defiance actions are awesome covered with unicorn farts and pixie dust ....... They come factory this way . For about 50 extra bucks you can pick your own cerial number , dealthstick1 has a ring to it ........
 
My point seems to be missed . While I agree about bolt thrust , the point I was addressing is tenon dia. After all that was the reason for not using a std Rem or Sav .
And as I said it was mine to use as a test piece .
I'm not sure the 338 Lapua is as high as stated (68000 psi ) . I think that's the British military's over pressure round . I don't know why the British call it over pressure round .
The steel has a lot to due with barrel strength , 41v50 is MUCH stronger than 4140 or of course 416 SS .
I DO NOT Recommend trying this . This was a experiment .

I read where Rem uses an extremely long freebore to keep pressures down. Matt

All Remington rifles have a very long free bore I think that is standard for them.

One of my friends has one I shot him a text to get some measurements for you. He is out of town for the next week for work. His shoots in the .5 to .75moa range from what I have seen. Personally I would not build on a 700 if anything else was available.
 
My test also include 338 Rem Ultra Mag Ackley and 338 win . Same barrel make ,same length. Unless your barrels are longer than 27" tha Lapua has only aprx 200 fps gain over the old 338 win . Virtually the same as a 338 RUMACK.
Because of the longer case length of the Lapua and Rumack the barrel length of the shorter 338 win case had 1"+ of actual bullet travel , which could account for the small vel diff.

Sir:

Self-promotion??? I pointed the fellow at a listing of 23 actions (excluding Remington) that support the 338 LM - only 4 of which are listed on the blog I commented about. Plus an action/receivers matrix with comparable specs. Plus a ton of barrel maker links. Have you actually been to my site? You realize that it is NON-commercial, right? Your comment was very much unappreciated!

Self-promotion you bet there is self-promotion. Here is the definition.

self-pro•mo•tion
noun
noun: self-promotion; plural noun: self-promotions
1. the action of promoting or publicizing oneself or one's activities, especially in a forceful way.

I guess I missed the part of commercial.


I do apologize for hurting your feelings and self worth.
