.25 WSSM necked up to .270, .308?

[lgm270]

The new .25 WSSM is one of those short & fat winchester creations designed to equal the performance of much longer rounds in shorter, fatter cartridge cases.  

The .25 WSSM equals the .25-06 or .257 AI and is offered in a super short bolt actaion M-70 rifle.  I'm wondering if anybody's wildcatted this round up to .270, 7mm or .308.  These should equal, in theory, the performance of the standard .270 WCF, .280 Rem and 30-06 Sprg.  in a much shorter lighter rifle.  

Anybody heard of this being tried?

Hi lgm270,

    No I have not but I am wondering how much lighter, or how heavy you actually want, the rifle to be?

    I have a normal old fashioned 270 Winchester chambered rifle so it's that dreaded (it seems  :roll: ) long action made by BSA about 45 years ago, it has a 22" barrel of a light sporting contour and even has the dovetails for the mounts machined into the action . The Bolt handle is hollowed and the stock which has a slim fore-end with schabel tip is hollowed out under the barrel channel except for the tip bedding area and the butt has two holes bored down into it under the buttpad. In all the rifle as it left the factory weighs 6 1/4lb. I have fitted a Parker-Hale 6E sporting apperture sight to the factory tapped holes on the left of the action and I have an alloy tubed old Khales 4X scope for it. So equiped it weighs just over 7lbs.

    Now Remington I believe makes Titanium actioned rifle and if you have one of those lightweight plastic stock jobbies ......................... just how much will the finished rifle weigh?

    The thing is have you shot a real light weight rifle? ......................... because I can tell you sighting in with hunting ammunition is not that much fun :roll:  I am looking for a lightweight scope with more eye relief that the old Khales I currently have as from the bench or rested in the ladder stand you have to watch that scope does not catch you, recoil is lively from a .270 Win in such a light rifle, which is why currently it has only the sporting peep sight on it  :wink:

    Not only that but with a little training of yourself with your rifle the bolt throw is not noticable either  :?  and it's not as if we are defending against a full frontal assault like the Great war is it?

   May I suggest you try shooting a lightweight rifle before spending out on one as it might not be to your liking  :oops:  Mine is part of my small BSA made collection and I enjoy shooting it occasionly, I also want to become much better with iron sights than I am currently with the view to hunting with them. Light weight rifles are really in my opinion a specialised field and it seems that I have aquired a few of them one of which if I can raise the funds I am hoping to bring to the US on a hunting trip in the mountains, which one it will be is undecided as yet but I have plenty of time to wring them out and see which one will be best for my needs on this specialised trip.

   As for the short mags .................... well if it's your cup of tea? then go for it! For myself I cannot see what the hype is about and I still read and hgear too many moans about feeding problems with them......................... hence I will stick wiht the tried and true  :-)  :wink:

I thought Winchester already did this with their 270 WSM, 7mm WSM and their 300 WSM!

[poncaguy]

No, the 270 is a WSM, the 25 a WSSM.......

The very short action rifles arn't any lighter than the standard short action rifles, and the short action Titanium guns are lighter still. So you actually gain weight.

The WSSM brass is a marketing failure so far and it might not be around much longer whatever the much higher cost than .308 based brass.

Who wants a wildcat that you can't buy anywhere for hunting when there are several standard cartridges that match their performance?

The WSSM cartridges feed lousy, even from guns designed for them.

I've got more downsides but it's late so I'm going to bed. I might list several more tomorrow.   :wink:

lgm270,
  While you could neck the WSSM up to larger calibers, you would not have sufficient Powder capacity for most expectations.  I own a 25 WSSM and love it.  Easy to handload for, feeds okay, and in the Featherweight, it is short, handy and light.  I shoot 117 grain bullets at about 2925.  They do not intrude into the case to the point of being a problem.  Don't listen to all you hear, especially if its bad. Mine shoots 75 grain vmaxes and 117 Hornady's really well.  But,,,,,,,,,,,,,,,, I don't think you would be happy going up in caliber with the WSSM. That is the realm of the WSM.
Just my 2 cents adjusted for inflation

Wildcat cartridges based on the WSSM case in calibers of 6.5mm(.264), .277, 7mm(.284), .308 and even larger has already been done.  Stop by the Short Mags.org(http://www.shortmags.org/shortmags/smclass.htm) forum and check out what the posters there are doing.  Despite what some want to believe the WSSM line of cartridges are selling very well.  There is no feeding problems as many rumors that are circulating around try to make people believe.  The cases are stronger than standard .308 cases due to them being thicker from the web to the neck.  More manufactures are chambering rifles for the WSSM cartridges and more factory loads are being introduced all the time.  If thy weren't selling this wouldn't be happening.  Listen to those that shoot the newer short-fat cartridges and not to those that haven't.  Lawdog
