WSSM Goes .25

September 23rd, 2010 5

Winchester Ammo, in partnership with Winchester Firearms and Browning, introduces .25-caliber cartridges to its Super Short Magnum Line.


.25 Winchester Super Short Magnum cartridges will be available in 2004.

The evolution continues for the Winchester Super Short Magnum line. In 2004, the .25 WSSM will be the latest “short-fat” cartridge to roll off assembly lines and onto dealer’s shelves.

According to Winchester Ammunition, the high efficiency of the “short-fat” design improves the interior ballistics of the cartridge. With more propellant surface area exposed to the primer, ignition is more consistent. In addition, the beltless shellcase allows headspacing off the shoulder to provide better centering of the bullet on the chamber. The new super-short action of the rifle also maximizes accuracy potential.


Winchester’s .25 WSSM Model 70

Like its predecessors (.223 WSSM and .243 WSSM), the .25 WSSM is reported to have equal exterior ballistics of longer cartridges of the same caliber. Per Winchester Ammo, the ballistics of the .25 WSSM are equal to ballistics of the .25-’06 cartridges, with 14 percent less powder and less perceived recoil–all in a shorter action rifle (See full ballistics charts below).

The .25 WSSM is designed with varmints and medium sized, thin skin game in mind.


.25 WSSM Browning A-Bolt Hunter

Additionally, Both Winchester Rifles and Shotguns and Browning are adding the .25 WSSM caliber to the Model 70 and A-Bolt Families.

Because the overall cartridge length of the new .25 WSSM is only 2.36 inches, the short action system on both rifles are a full half-inch shorter than previous WSSM models. Winchester Rifles and Shotguns .25 WSSM Model 70 will be available in Super Shadow, Ultimate Shadow, Featherweight, Coyote and Stealth models. The Browning A-Bolt .25 WSSM will be available in Hunter, Classic Hunter, Stainless, Varmint, and Medallion models.

    I got into the WSSM after they stopped making them. I purchased 2 .223 WSSM and a .25 WSSM. I have taken the .25 WSSM to Africa twice now. I am in Africa currently. My trip this year is for 3 months. I brought a .17 HMR for shooting monkeys and baboons, .50 Cal. muzzle loader for big gave kudu and such and the .25 for everything inbetween.

    While here in Africa I work on a hunting ranch and take clients out for hunts. I have had two use the .25 WSSM for their hunts. One took a warthog at 125 yards in the shoulder it did not take a step. The other took impala shot in the head at 90 yards of course it did not take a step. I have taken duiker, impala and 5 springboc 2 at over 300 yards. I either use the 115 grain or the 120 grain winchester ammo. Both shot exactly the same at 100 and 200 meters here in Africa. Everyone that shoots the rifle wants it. It is a model 70 Coyote, laminated stock, stainless barrel. I have a current order to fill for a kudu and will use the .25 for it also. I shoot head shots out to 200 meters and I guarantee you it will hit the ground without taking a step. Oh by the way I took a bushbuck that will make the SCI books with the .17 HMR, head shot of course. Shot placement is the killer not the caliber.

    I bought a Browning A Bolt Stalker in 2007. Since then I have taken 8 deer with it. All 8 have dropped in their tracks. Ranges were from 20 yards to 180 yards. My load is my own handload using Hornady 117 SST bullets. I also got some 75 grain V max reloads with the gun when I bought it. These rounds shoot to within 1" of the point of aim of the 117's. I have never had a gun shoot as well as this one. It's a keeper.

    I tend to go with more conventional and established cartridges, but just bumped into a clean SH M70 Featherwight in 25 WSSM at a local pawn shop.

    I had been looking at a Kimber 84M .257 Roberts for domestic use as a deer & pronghorn rifle, but that little M70 is a cutie.

    Anyone comment on accuracy of this round (good or bad) and any issues reloading? The TSX 100s & 115s might make this little gun deadly…

    Thanks…

    I got 3 browning mountain ti in the 25 WSSM cal and have shot 2 of them deer hunting in the south and the other one is still new in da box, gonna pass that one down… i have yet to lose a deer with either rifle i shoot, just different scopes, shoot em from 60 yrd's out to 200 where i hunt… couldn't ask for a better cal for shooting deer, i use the winchester 115 gr silvertips and they are deadly to say the least…great gun from browning and great load from winchester…. just better stock up on some ammo, it's already gettin kinda hard to find around this neck of da woods…

    I have a model 70 coyote in 25 wssm and a stealth II in 25 wssm each with elite tactical scopes and they both are amazing. I have killed 20+ deer at yardages from point blank to 688 yards and havent had to track 1 of them. I use the 115 grain silvertips and for deer sized game this is the ultimate blend of knockdown power and felt recoil. These two guns are the envy of everyone who has shot them!!!!!
