| 338 Lapua Mag. in a Yugo Mauser action? | Login/Join |

Hi, a local gunsmith that makes some custom works, says that he's making such a rifle; I have some doubts about the feasibility. What is your opinion? Thanks. | ||

since the lapua is baically the 416 rigby brass.. .and most people think the 416 rigby doesn't fit into mauser 98s unless done by a highly skilled smith, i would say no jeffe #dumptrump opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

My first thoughts are the same as yours. As usual just my $.02 Paul K | |||

The .338 Lapua is somewhat shorter than the Rigby but, depending on bullet length and seating depth. it's still a long cartridge. Regardless, it's still as fat as a Rigby and my opinion is that you've got to remove too much metal to make it safe or practical. "I ask, sir, what is the Militia? It is the whole people.

Rick, the number of 416 rigbies done on mausers is rather small.. in fat, they are notably by their scarcity. the round it too fat and too long for the geometery to work for most smiths, and the amount of metal to be be removed is very chancy with the lapua being so close to the rigby, with even less taper, therefore more metal in the front, is removed. It's both a question of length (that can be overcome, to a point) and width.. that can't really be done eaily.. the difference between perfect and ruined action is amazingly thin. When combined, you run into trouble, and sure it CAN be done, but the smiths that can do it are VERY rare, and the prices VERY high. Now, if the guy wants to learn how to do it, I don't know how many actions a smith would have to go through before getting it perfect, but my guess would be at least 10 or 15 before he finally made one that was both safe to shoot and feeds. jeffe #dumptrump opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

Yeah right. He'll spend more on the first box of shells than he will buying the action! for every hour in front of the computer you should have 3 hours outside | |||

IMHO there are much better ways to get a 338 Lapua. I wouldn't shoot within 2 benches of a 338 Lapua built on a Yugo Mauser. The 416 Rigby is a low pressure round the 338 Lapua ain't. I don't think the Lapua would take very long to frag a std length converted Mauser. Buy an action made for the Lapua.............DJ ....Remember that this is all supposed to be for fun!.................. | |||

Yeah,you could do it on a Yugo.But why not use a VZ24. | |||

Some were vz24's, some were K98's, some were FN intermediates and others indigenous intermediates. I'd not attempt it on any.  Aut vincere aut mori | |||

Sir, the consensus here is that your average military Mauser of any maker simply is not big enough. And frankly, I agree with this. There are other action far better suited to a 338 Laupa. Jason "Chance favors the prepared mind." | |||

There has been quite a discussion of major magnums on surplus actions causing bolt setback (bolt lugs make indentations in their recesses in the reciever) Re-heat treating may help, but why spend big bucks on a $50 action?? "Pick out two!" - Moe Howard  | |||

Hi Moe, welcome to AR... Have a look at this for what can be done to an mauser http://www.weaponsmith.com/550-exp.html Why spend bucks on a $50 action?

Yep, I worried about that with my P17 project in .470 Capstick but since I only plan on loading to match .470 Nitro loads I figure I should be ok. | |||

FWIW, I've seen a few cases where two mausers are cut ahead of the thumbcut, then the half from one is welded to the other. The result is one micro-mauser and one magnum mauser. Of course, you do have to re-heat treat  | |||

Yes, and honestly, that isn't such a great idea either. Few realize that the bolt gets awfully long and the normal end to end wobble is greatly exagerated when the bolt is fully retracted. Not conducive to the smoothest functioning. Let the flames begin.  Aut vincere aut mori | |||

Not only that, but now day and times, not hardly cost effective unless you're doing your own work. Jason "Chance favors the prepared mind." | |||

I dropped off two VZ24 actions for shortening and lengthening this week, when I was there to pick up other welding. The guy has to cut the: 1) reciever 2) bolt 3) firing pin 4) magazine 5) follower 6) bottom plate He has to cut it twice in one of the actions. That would be 18 cuts and 18 welds. I'll deal with the springs. The intended rifles are: 1) 338Lapua 2) 6mmBR. So one goes from ~ 3.25" to 4" and the other goes from ~3.25" to ~ 2.5", minus the 3 cut widths. | |||
