7 mm weatherby mag caliber
- Thread starter dragonbreath306
- Start date
I had one a few years back and used it to conduct an experiment with several 7mm Magnums. I found it to be the most efficient of the big 7s. Anything in particular you want to know? It is easy to load for and I made all my brass from W-W 7mm RM brass, very easy and performs every bit as good as 7mm Wby brass, maybe even better. My pet load was 160 Nosler Part and IMR 7828 if memory serves.

Excellent thank you. Yes I was just curious I recently have been working an a few loads for my 300 weatherby and I'm too addicted to quit now so I think this might be my next purchase all tho 7 mm short mag could be a contender! But I most likely will go with the 7 mm weatherby. I just love the weatherby cartridges. Is your loads a fair bit faster then 7 mm remmies that u have experienced? The rifle I have my thoughts on is the euro mark and wondering how much of a difference recoil would be in comparison to my 300 weatherby vangaurd model it's In a synthetic stock. It seems manageable to me but a long day of shooting will start giving me a flinch. Also what primers would u recommend for these mags I did some research and it seems that Remington mag primers seem to be the hottest so far I've been using some old Winchester standard lrg rifle primers. I'm told that mag primers aren't nessicary but some people tell me the opposite?
The old rule of thumb for magnum primers that I have used is ....with all ball powders and any case loading more than 60 gns of powder. I have always used either CCI 250 or Fed 215. The recoil is significantly less in the 7s than the 300 Wby, I've been using a quite light 300 Wby in a Mod 700 Stainless for more than 20 years and it has worked perfectly for everything but heavy dangerous game. If you don't have the 7 Wby yet and already have the 300 Wby, may I suggest you look at a 257 Wby instead of the 7. Much more compliamentary and less overlap with the 300. And a truly amazing cartridge in it's own right. Then all you need to add is a 375 Wby and you're set for hunting anything, anywhere, anytime !!
Or they're not, and a 7mm-300 Wby is what you need. -dan
Had one of them for years Dan, built on a Ruger #1 with a 28" bbl, took a stone sheep and a moose and several caribou with it. Superb cartridge, a little tough on capes and meat, but a devatating combo. Might be time to build another, considering the powders now available.
Radiused shoulders are a beautiful thing, so sleek and ###y.............

Love mine. Shoots great too!
I agree with 444shooter ! Radiused shoulders is weatherbys way of saying they are serious about accuracy and horsepower. Basicly if you walk into a club and there's two cartridges in the corner just ready to be felt up what are u going to go go feel up the short fat one with the ugly turtle neck or u taking home the tall skinny one with the cute belt and nice curves. It's a no brainer really lol.
Thanks for the replies guys!

It sounds like you are trying to insinuate that radiused shoulders somehow increase accuracy. If that is true, they why don't the top benchrest cartridges use radiused shoulders? The BR and PPC cartridges certainly don't have radiused shoulders.
I concur stubble!!! I'm curious though, has ANY radiused cartridge ever won anything other than bragging rights? Which BTW most WBY cartridges have lost both speed and accuracy to other similar non radiused cartridges, so I am not sure what there is to brag about.
Oh wait! They still cost more than anything else!!!
Seriously though, I have a love for a few WBY rounds, like the 240, 257, 340...... I just don't understand the WBY reputation for being so...."sh!t hot", lol.

I think mr weatherby is one of those guys that said u know what lets make this cartridge faster. Then after he produced his new calibers he said ha take that Remington and Winchester . I agree with some of you that radiused should don't make a world of difference. But I'll tell u what next time ur at the store look at the boxes that tell u muzzle velocity on the box weatherby might not be a whole lot faster but guess what 9 times out of ten there still faster. Besides most of there cartridges are intended mostly for hunting not target practice. Which is exactly why I choose them. Just my opinion.
This!!
Plus the fact that Roy Weatherby himself, after extensive tests, admitted that the radiused
shoulder made exactly "zip" difference in the performance of any given cartridge.
But if you love the design....more power to you!

Radius shoulder or not, my 7mm Wby is faster than the 7RM - both using 24" barrels.
It was a sales gimmick. And while there is a lot of fast cartridge competition out there now, when Wby first introduced these cartridges things were pretty scarce. All the "std" magnums came along well after Wby's products generally, so yes, at the time they were "hot shot". - dan
