Folks, I know some of you more experienced gun builders have worked with just about every caliber known to mankind. A friend has a Dakota African take-down in 416 Rigby, and wants to add a 2nd barrel in a smaller caliber. I know the 338 Lapua would work, and that in the past they created a 30-416R wildcat for 1,000 yard shooting. Are there other calibers in the 300-350 range that may have a tapered case but use a 416 Rigby-sized boltface? Thanks...Biebs | ||

Biebs, the .338 Lapua has much development data, and supplies are easy to get. Enormous potential for long-range accuracy. BUT: recoil much more uncomfortable than the .416, and barrels burn out very quickly. | |||

366 DGW - 416 Rigby necked down to 9.3mm. Pretty impressive looking cartridge. | |||

Jeff, my first advice was the same....do a 450 Rigby for the 2nd barrel. But I believe he wants the 416 for the "big bore", so he's looking for something less. | |||

Does he want to do a wildcat? There's the .348 diam. bullet, and the .323 (8mm) too. In .358 there are countless bullets to choose from I think. .338 Norma Mag is another. Jack OH GOD! {Seriously, we need the help.} | |||

The 338 Lapua is a good choice, but in a hunting rifle you have not all the potentiality of this cartridge ! You are on the level of a 340WM cartridge ! | |||

Why not a 30-378 Weatherby. I believe rim diameter is .589 on both, brass is readily available as is a wealth of reloading data. Loved my Accumark.

Biebs, IMHO, going to a smaller bore, such as a .308", .338", .358", or even .366", on the .416 Rigby case is going in the wrong direction. All it will do is create a grossly overbore cartridge that will offer no real advantage - for any hunting purpose - over a "normal" sized cartridge of the same caliber. I agree with Jeff. Your buddy needs to go bigger, not smaller!  Mike Wilderness is my cathedral, and hunting is my prayer. | |||

300 Lapua is the .338 Lapua with shoulder changed to 25 degrees instead of 20 degrees, and necked down for .308 bullet. Lapua made brass with proper headstamp once upon a time. I want a Dakota Traveler take-down combo in .395 Tatanka and 500 Mbogo. | |||

What is the bullet to weigh in .395 Tatanka? 500Mbogo uses 570 grn bullet right? Jack OH GOD! {Seriously, we need the help.} | |||

Too bad, he did not plan ahead and get a belted magnum. Then he could choose all the barrels he wanted from 7mm Rem to 458Lott. This would be a nice set: 300Weatherby, 375H&H, 458Lott. So many options. | |||

Regarding 2RECON: IIRC, he is one of those German engineers, and he was in on the design of the .375 Tornado around 2000-2001. Of course we now need a 500 Tornado: a true .500-caliber on the .338 Lapua Magnum Has boom stick got the drawings for this one already worked out?

RIP 2Recon and one of his buddies got nearly all the .500 dies, 50 B&M, 50 B&M Super Short, and 50 B&M AK. I think they were going to work on some rifles off those? Also brass and things like that as I recall. B&Ms in Germany, how cool! Brian says should have you sights BLACK back this week, should have on the gun, and should have gun next week. If the sights come back this week as he was told. Everything else is RTG. (Ready to Go). I apologize for this intrusion and taking off thread, please forgive.

Doc M, Going slightly off topic now and then is to be expected, and it always leads back to topic. Only a "Joe-Bite-Me-a-hole" or an "Al-Gore-a-sex-poodle" would possibly complain of it. Thanks for the update on the B&Ms. "Bavarian Munitions?" | |||

Biebs, I have the answer! 1. Sell the Dakota. 2. Buy a Blaser R93 with a semi weight barrel in .338 Win. Mag. 3. Then, buy a second barrel in .416 Remington. 4. Use the extra money from the sale of the Dakota for his safari. Voila! He wouldn't even have to change the bolt face. When it comes to take down rifles, Blaser is always the answer but you already knew that.

I think a 500 Mbogo necked down to 458,416,375 and 338 are potentialy good rounds for special purposes 577 BME 3"500 KILL ALL 358 GREMLIN 404-375 *we band of 45-70ers* (Founder) Single Shot Shooters Society S.S.S.S. (Founder) | |||

I think his 'smith settled on just machining a 2nd bolt for the rifle. That way he can do just about whatever caliber he wants. | |||

Dave, you're preaching to the choir on Blaser versatility! I am just finishing up a rifle for someone now, with 300 WSM and 375 H&H barrels, with a synthetic stock to be sent out for camo dipping. Custom Talley mounts, a solid mounted Zeiss 2.5x10 on the WSM barrel, and a QD mount with a Trijicon 1.5x5 on the 375. | |||

@michael458+RIP, working on 98MAUSER chambered for 50B&M+50B&MSS, also on one in 500Phantom You REALY like to have a 500-338Lapua..?? Once i´ve necked it up to 458"....mayby....lets get back to the CAD-Software and look if there´s some kind of shoulder left if necked up to .510"..... Best 2RECON | |||

| one of us |
2RECON, My 500 Mbogo 3" and Jeffeosso's 500 AR (short) both have 20-thou-per-side of shoulder or a total of 0.040" difference from shoulder to neck-1 diameters. The .500 Tornado would be intermediate to those in length and use the .500-caliber instead of .510-caliber bullet, so a .050" differece or 25-thou-per-side shoulder is easy. I would call it either the "498 Lapua" or ".500 Tornado." | |||

Multiple barrels in a take down format? How about one of these rifles- Mauser Arabesque Bolt face size is no issue. You just get the another bolt face for the caliber barrel you are using.
