I have a .338-378 Weatherby Magnum rifle that needs to be rebarreled. With a 338 Lapua Magnum headed my way and the desire to get away from the Weatherby brass, I'm having a little trouble identifying suitable conversion calibers. It looks like this rifle caliber has an "odd" base diameter that will force me to change or alter the bolt. I'm at a loss whether it is better to sell this rifle as a donor action and start fresh or, convert this rifle to a 416 Rigby or 404 Jeffery based cartridge. I would like to get something in the "mid" .40 caliber range, preferably without a belt and not overly high pressure to be suitable for very hot environments. I'm not overly opposed to a .458 Lott or .470 Capstick though so, I have considered selling the Weatherby and buying a CZ Safari Magnum or Classic. Calibers like the "AR" (Remington Ultra) series and the 470MBogo seem to be incompatible so, I'm having trouble finding suitable alternatives. Ammoguide initially seemed promising but, the case head dimension seems to require a bolt conversion and prevent a more economical rebarrel option. Am I missing some good options for my Weatherby rebarrel options?

the x378 weatherby has a parent case of the 460 weatherby, which, is basically,. a belted 416 rigby. since you don't want a belt, that leaves the 550s and 500/510s out however 470mbogo is a drop in 450 rigby 416 rigby 338 lapua 500 AR 500 KX/Mbogo (both basically unbelted well's) 450 dakota opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

Actually, the 378 is the parent case for the 460. Go with the belt and make a 416 Wby. | |||

Since when is Lapua brass better or cheaper than Norma/Weatherby brass...?? How are .338 Lapua ballistics better than the .338/378 Weatherby..?? Sid - sell the rifle and start from scratch if you prefer the Lapua. | |||

I own a 338LM (actually the rifle is being built on a Stiller TAC338 action) for use with my suppressor. The Weatherby is used up as it is so, it needs a new barrel at a minimum. If I rebarrel, I would prefer to avoid the Weatherby brass. I'm not saying Lapua, Norma, Weatherby, etc. brass is better or worse - I just don't want to mess with Weatherby brass anymore and prefer to use a wildcat that does not have a belt. I toyed with the idea of a 458Lott and 470Capstick but, I have always admired the 416 Rigby from afar. It looks like I can convert this rifle to a 470Mbogo which sort of gives me a souped up 470 Capstick and gets rid of the belted brass. Converting this rifle appears to be cheaper then getting a CZ Safari Magnum and a few mods so, that's what prompted the question to start with. A CZ with the 375 H&H necked up to to .40 caliber mentioned in the other thread is tempting. The purchase of a 458 Lott is tempting too. However, the cost of the CZ and AHR update is a lot more money since I already own the Weatherby.

My Lapua brass experience is limited currently but, so far I find it to be very consistent and high quality. If I were going to blindly pick some common centerfire brass to reload, I'd take Lapua. It is more consistent in general then the normal stuff I get from Domestic manufacturers. Maybe one of these days I'll try some Norma in one of my 308Win rifles.

I know this much. loading up ammo for my 7mm Allen mag with lapua brass, I can load up 110 gr of wc872 behind a nosler 160 for 3575 fps and get five fireings, before anealing. I have had the load up to 115 gr/3712 fps and didn't lose the pockets, using norma brass the pockets are loose after 1 110 gr firing. using lapua brass is one option I'll always opt to go with if possible.

the 404-375, 458 Lott and 470 Captstick would not work on your action, they all share the same .532 bolt face, which is too small for your rifle. 416 or 450 Rigby would be a good choice. If you want to play with a wildcat, neck the 416 Rigby up to .423 or .435! If you think every possible niche has been filled already, thank a wildcatter! | |||

Isn't the 470Mbogo an improved 416 Rigby necked up to .470?

Not sure on the Mbogo...but another thing I just thought of is that you could do a Lazzeroni cartridge on that action. They have a .577 case head vs the Rigby .580 Not sure if anyone suggested the 450 Dakota. You also have the 495 and 500 A-Square, but the retain the belt from the Wby case (which if you already have the cases laying around....) There is the 475 A&M Magnum as well. If you choose the 470 Mbogo, its going to be more then just a beltless Capstick lol you're adding a decent amount of extra powder in there. If you think every possible niche has been filled already, thank a wildcatter! | |||

You guys are more knowledgeable than I but there is another option you can turn the belt off leaving the rim for single shots & then you have a .416 rimmed case to work with. | |||
