short mag

[Karl Blanchard]

im kinda curious why some people prefer short mags such as a .270wsm over just a regular old .270. Is there any real advantage to having a short mag? ballistics wise?

I would assume that standard vs sm would be their standard brother cartridge.  300wm/300wsm, 7rem mag/7wsm etc.  I Could be wrong though

300 wsm is faster than a .308 Win too ! 

Yes it is, and that's the question that was asked- how a WSM compares to a "standard" cartridge, and specifically he said the 270 WSM and the 270 Win.

So THAT makes Since Why YOU Compared the 300 and 7mm  to a 30/06 and a 280. Lol

Yes, that's right. Not sure why that's funny though.

The wsm was designed mainly for the use in short action rifles they based it off the 404 Jeffery which is a non belted magnum case unlike the wm which uses the 375 belted mag  case . They ended up with slightly more speed and accuracy as a byproduct .

I guess we all look at it differently. The 300 WSM falls right between the 30/06 and the 300 Win Mag. I always think of the 300 WSM as just a 30/06 on steroids. It certainly can't match the 300 Win Mag, it just can't. Less powder capacity equals less velocity, regardless of it being less efficient.

  yep.  For the purpose to have a short action chambering made to mirror the performance of the standard belted magnums

The wsm out performs the 300 wm . Across the board , recoil and speed and inherently more accurate.

Not in velocity unless you're running it at higher pressure.

With the 150, 165, and 180's I could get them hotter in the wsm.  Much more pleasant to load for too.  Love em!

I own and shoot several WSMs and their counterparts. I like them. The 300 WSM and the 300 Win Mag are kissing cousins. The 270 WSM beats out the 270 Win. The other WSMs lack significantly in acceptance.

They're all orphans with no parent although closely related to the 404 Jeffrey.

Short mags matter.

They're all orphans with no parent. Winchester started from scratch in developing the cases.

    they do matter!  270 wsm will be the next firearm purchase I make.  I think the wife needs one.  Ya that's it, the wife!

Factory winchester ammo the wsm run approx 100 fps faster with about 150 more fps of ke. Over the 300 wm

Anyone have any load data to share for their 270 wsm?
