what's the deal w/shortmags?

[LtCCMPUnit42]

Ok guys, NOT trying to start a caliber war. Just trying to learn about something that I haven't been around and don't know about.
What is the advantage of a short magnum over a conventional magnum cartridge?
I have a5.56mm, .308 WIN, 30-06, 300 Winmag, and a 7.82 Lazzeroni Warbird, and just by studying the balistic charts, I don't see anything that can be done w/ a short mag that I can't do w/ one of these.
I HAVE NOT shot, or been around ANY short mags. I am looking for enlightenment from the learned. Any discussion is welcomed.

Short action on your bolt gun will lead to faster follow up shots and theoretically a stronger receiver. There is also the concept of the fatter column of powder giving a more consistent burn and therefore better accuracy and even less recoil due to a more efficient use of powder. IMHO, I think all of those effects are overblown.

Short fat cartridge is also a bit more efficient - less power for the same speeds (supposedly).

Thanks Dude, I think I'm beginning to get part of the concept.

Short mags are designed to acheive the advertised velocities from a 22" rather than a 26' barrel. Hence the more effecient burn from a short fat cartridge. Thats my understanding anyway. I have a 7mm WSM that I use for deer and I couldn't be happier.

I suspect lots of marketing hype to sell new and "improved " rifles.
That said I think a 6.5 short mag. would kick arse.
And it would be a great way to get to know your gunsmith / barrel changer on a first name basis

Biggest gain I would think is lighter weight rifle for a given amount of firepower

I think the main selling point is short action rifle = lighter weight while giving equal to better ballistics.

I have a .270WSM and like it alot.

People like short actions for the lighter weight and the better handling characteristics.

My only short mag is a Winchester .270 SM. Only complaint is Ihave not been able to duplicate factory ammo performance.
