Title: 25wssm necked up to 7mm?
Post by: bankwalker on November 26, 2009, 06:58:19 PM: so what do you guys think of a 25wssm necked up to 7mm?

my buddies dad just went through the process of necking up his brass and getting his m70 re-barreled in 7wssm
he has only shot it a couple times at 25yards, it seems to shoot ok from what he has told me.
i cant wait to see what he comes up with, and how this performs.

should be interesting.

though i really do not see any advantage of this. other then being different.

Post by: bobcat on November 26, 2009, 07:01:33 PM: Yeah I would guess it wouldn't be much different than a 7/08. Why bother? I don't get why people like wildcats nowadays when there are so many factory options available.

Post by: JackOfAllTrades on November 26, 2009, 07:25:04 PM: Nothing wrong with wild cats. If you read history about many of the currently offered factory cartridges, many where derived from necking something up or down, changing shoulder angles, lengthening or shortening cases to attain the performance desired. Necking up a 25wssm to 7mm doesn't make a lot of sense to me because much of the wssm success in increased pressure/velocity is related to the shoulder angles implemented for that shorter fatter case. I would see less of a performance improvement but rather better bullet selection availability. I certainly would not have spent the money on this conversion. Yet, if you look at the 338-06, which is a necked up 30-06, there is a good following in that cartridge. To each his own. In this case, I would figure that re-barreling to 7mm-08, 270AI, or 280rem would be a more productive choice. Now he's got a wildcat that not only requires some of the most expensive brass to purchase, doesn't/won't conceivably produce any better performance than a factory offered round, and he's still got to produce his own cartridges by sizing and fireforming.

Doesn't make much sense to me. I hope he finds what he's looking for though.

Post by: bobcat on November 26, 2009, 07:37:45 PM: Yes I realize many of the current factory offered cartridges were derived from wildcats. And that's the reason I don't understand the need for wildcats anymore. The 338-06 is a great wildcat and I believe is now chambered in at least one factory made rifle... the Weatherby. No? I could actually see myself owning one of those. But really, I don't believe it will do anything that the standard 30-06 won't do. A guy could also go with the 325 WSM if he wanted a larger caliber with not much recoil. But then you've got the more expensive brass to contend with. Myself, I've just got to the point where I don't see the need for anything but the standard cartridges. That's why I've got a 243 Win, a 270 Win, and a 30-06. Boring I know, but they get the job done, just as well as anything else.

243 Win, a 270 Win, and a 30-06

Fine cartridges to have in everyone's arsonal. Once you have them, then tinker with a wildcat. Rifles chambered in those three will take everything in the lower 48. Maybe add a .30magnum or larger to the collection. I agree that the WSSM's and the necked up standard cases are over rated. Especially the newley developed 338Fed.

Long before the WSSM's, I moved toward a wildcat that is a necked down belted case because of the balistics produced with less powder than it's longer brethren. I don't own any, but I'm a bit fan of the Ackley Improved cartridges.. What the factory offerings should be I guess. Wring out every bit of velocity possible from any standard case. I do have an old Enfield action that I plan on building a 30-06AI for my eldest son.

I did a little research on the 7mm WSSM.. There's a little bit of performance increase overe the 7x57 and the 7mm-08. No advantage over the 280Remington or the 270Winchester. I guess if a guy has money to burn/play with.. To each his own.

Post by: bankwalker on November 27, 2009, 11:42:50 AM: well it shooting 3/4" at 100 yards. dont know the fps though. so i guess it was worth the time to play.
Title: Re: 25wssm necked up to 7mm?
Post by: Curly on November 27, 2009, 12:00:11 PM: I'm guessing way less velocity than the 7mm-08.

Edit - oops. I hadn't read JackOfAllTrades post when I posted my guess. :P
Title: Re: 25wssm necked up to 7mm?
Post by: Curly on November 27, 2009, 01:14:10 PM: I spent some time googling and trying to research info on this wildcat. Not much info about it that I can find. I guess some guys are building AR's for this cartridge.

I can't see much use for it in a bolt gun...........
Title: Re: 25wssm necked up to 7mm?
Post by: bankwalker on November 27, 2009, 02:46:52 PM: i think it just has to do with the cool factor.

he has a 22-08, 6mm wsm, 7mm wssm, 6mm-06, 25-06 and 30-06 AI's.

he has just a bunch of stuff "because he can" with no real need or use for them. the guy hunts with one gun and one gun only. and the rest are just for range work.
the 7mm wssm was just a thought that he ran with, having a m70 that didnt shoot worth a darn it was the perfect platform to play with.

i frankly dont see any need for it personaly. i would much rather have a 7mm-08 AI or even a 243 AI.

Post by: yorketransport on November 28, 2009, 08:33:55 AM: I think it sounds like fun. Not because it fills a need, but because it's different. There's nothing that bugs me more than going to the range and having the guy next to me shooting the exact same gun. ;)

Post by: AWS on November 28, 2009, 09:40:35 AM: It sounds like a very nice rig. The action for it will be about 1/2 shorter than a 7mm/08 and will be more efficiant in burning powder. Shorter stiffer action more bang for a bucks worth of powder and big enough to hunt anything in this country. I like it.

Post by: Jamieb on November 28, 2009, 10:23:57 AM: I've put together more then one rifle just becuse I wanted something diffrent to play with, even though I knew going in that I wasnt going to build something (better), just something diffrent to play with. It sounds like a fun project.

I kinda figure like any hobby people build new and different guns because it is enjoyable to them. Same reason they own more than one gun or one caliber because they can ;)

No real ballistic advantage at all. I supose that it would be more effecient, but it wouldn't come close to matching 7 WSM performance. It would have the super short action though, so you could save .5" over a standard short action.

Post by: Red Dawg on November 28, 2009, 08:41:57 PM: I agree that this would just be a fun project to play with. Sometimes a guy can get bored with the same old cartridges. If I had the ability to do it I would love to try out a project like this.
Title: Re: 25wssm necked up to 7mm?
Post by: JackOfAllTrades on November 28, 2009, 08:58:46 PM: Oh, I don't knock building any gun as any sort of fun project. As a different look.. I love the look of an airbagged slammed mid 70's Chev pickup truck, but they are utterly useless as a truck anymore once a guy does that. Still, people enjoy that sort of project. For a rifle, I guess I think a bit more practicle or functionally superior to something else that's available.
