short mag

[cem3434]

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

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

180 grain bullets are virtually the same in both calibers. Less than 180 grain, the wsm kicks the wm butt. Anything over 180 grains, then the wm is slightly better. As Coach suggested, you might want to look at a couple more charts.

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

Look at Alliant Reloader 17 on the web for some load info.i was running 62grains behind 130 Accubonds and getting 3250 fps
It is a Flat out killing machine

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

Well thanks, that's good to know. Although I have to ask is that from velocities that you chronographed yourself or are you going by Winchester's data?

Another thing to consider is the Win Mag needs a longer barrel than the WSM for best results. So if the numbers given are from equal barrel lengths that's not a fair comparison.

I've always liked the WSM's, just haven't yet felt the need to replace the rifles I already own. But when I do I'll probably get one of the WSMs. Not sure which one, I really like the 7mm but it's the least popular so I'd be better off picking one of the others.

  that's probably one of those rounds that really POP on impact!

All my data is chronographed.  Wsm and wm both have 24" tubes

The wsm's are pretty tough to beat for an all around deer/elk rifle.
As for accuracy....even the benchrest guys like them for long range.
I like the 300 wsm but I also think the 7wsm would be great.
I prefer the non-belted cases for reloading.

Also have about 9lbs of re17 I'd be willing to part with. Great powder for the wsm. I just ended up using h4350.

Never understood why the 7 never gained traction.  All the benefits of a short mag combined with high B.C. bullets should have made for a winner.

How is it a fair comparison if the wm has a longer barrel?
 
A longer barrel on either caliber will give more velocity.

Easily one of my favorite cartridges....no doubt my next rifle will be in 7 short

A lot of good 7mm bullets!  I think this caliber is fairly common in 1000yd benchrest.

  finding brass would be my only concern but then again I don't really watch for that particular item so maybe it's readily available.  I know 300wsm is a pain to track down

Just the way I look at it I guess. I've always thought any of the "standard" magnums from 264 Win Mag up to 300 Win Mag should have a 26 inch barrel, while a short mag should be good with a 24 inch. Really who wants a short action rifle with a 26 inch barrel?

This is all really just splitting hairs though. The rifle itself is more important than the cartridge it's chambered in.

Some guys like to run them in a long action to cram more powder to push those long hybrids!

It seems to me that the wsm also benefits from a longer barrel. I have a savage 116 in 300wsm with 24" barrel and a custom 300wsm with a 26" barrel. I get 80-100 fps more out of the longer tube. Built the gun with a 26" barrel for long range.

I agree on the splitting hairs.....for hunting purposes you save a little weight in a shorter action is about it.

I don't reload but save my brass. Next time I see you I'll have some 300 wsm for you to stoke up and kill stuff with. If you want it sooner I can mail it.
