Need advice from you...please.
If you build a .338 LP it's not recommended to use a Remington action. Becuase of the safety...? Not strong enough.
What about a Rem.700 Safari .416Remmag.
That should be safe, or not????
I can get one cheap.
Choate stock, and Leu.8,5-25X50LRT
Please advice.... anything help's
Thank's in advance
the .416 Remington uses the standard magnum action. It is not recommended to build the lapua or the large Weatherbys on the M700 action because of the amount of metal that must be removed while chambering these large cartridges. It leaves a thin chamber wall where the action threads are cut, and this is potentially unsafe, especially when hanging long, heavy barrels on the ation.
Many smiths do the 338 Lapua or 338/378wby on the 700's. The 416 rem uses the same action as all the long action 700's do.
My brother has a 32" straight taper Pacnor barrel to .800" at the muzzle on his 700 in 338/378wby in a Choate Sniper stock. It shoots really, really well using the 300gr SMK at 3000 fps at 65k psi on the Oehler 43.
You ask around enough and you'll find that it's the biggest anyone will go with that bolt size, many just won't. You find one that has failed because of it's bolt dia or size barrel tennon, you let me know.
[img]images/icons/wink.gif[/img] I never have and doubt I ever will. That many smiths just don't stick their necks out and do things to get them into court like that, and Savage wouldn't have a barrel in 338 Lapua because it isn't safe either.
I'm getting ready to build two rifles based on this case right now, both are using 700 actions too. Good luck and don't just take my word for it either, you do the research and you'll find the same thing I did. [img]images/icons/wink.gif[/img]
Am curious, the reloading manuals that I have read show the 338 just a little faster than the 340 Weatherby (50 fps). They also show the 338-378 Weatherby much faster than both (200 fps faster than the Lapua). Why are so many saying that the Lapua is comparable to the 338-378? It seems more comparable to the 340?
Portate bien o te lleva el cucuy
You're right, the 338 Lapua Imp is comparable to the 338/378wby because of the major improvements done to it. The 338 Lapua leaves alot for improvement with it's very tapered body and shallow shoulder angle.
The 338 Lapua case was based on the 416 Rigby necked down and shortened, neck mostly. The Rigby was found too weak at the intended design pressure 470MPa, so the guys at Lapua redesigned the case from scratch. Later the army found the 470MPa too high, so for the CIP a max pressure of 420MPa was selected. Compare this to the 430MPa of magnum cases, 440 of Weatherby and 460MPa of the 300Ultra one can understand why such a large case as the Lapua seems slightly anemic. One should however keep in mind that the case is left as strong as it was designed. If one dares to enter the world ower the max loads in the manuals (max 420MPa), one will find that the potential of the standard case is sunstantial.
Gentlemen, I have followed this magnificent site for quite some time. I have now got my first reamer, a Lapua Mag Improved (+FL sizer reamer) of my own design and feel an urgent need to tap some of the potential of this site, and, perhaps with some luck, contribute with some minor point some day.
