This from Winchester.com. The wsm is faster and flatter. I have the 7mm wsm and I love it.

RE: difference in .270 and .270 wsm
 

Take a look at post on Remington model 700xcr in 270wsm first deer. I am getting a chronographed 3200fps factory 150gr.Winchester Power Point ammo.

RE: difference in .270 and .270 wsm
 

awesome . a little more power. is that from more powder ? thanks.

RE: difference in .270 and .270 wsm
 

Yes,also it has a shorter burn colum with the shorter fatter case.

RE: difference in .270 and .270 wsm
 

not enough to make it worth buying both. i don't see the need for most short mags.

RE: difference in .270 and .270 wsm
 

Not enough difference to argue over. If you are buying one or the other, I would would go with the 270 wcf for no other reason than ammo availability.

My brother has a 270 wcf, and his friend has a 270 WSM in the identical gun (Ruger M77 MkII stainless/synthetic). They sight in together every year and swear the 270 WSM recoils 50% more than the 270 wcf. This is based on their perception of the recoil and has absolutely no scientific basis.

RE: difference in .270 and .270 wsm
 

Depending on where you live, availability of an assortment of different kinds of ammo and .270 Rem Core Lok at about $12 a box versus WSM at about $40 a box.

RE: difference in .270 and .270 wsm
 

I shoot a Browning A bolt .270 short mag and love it. I do agree on the ammo options though. The only ammo I have ever been able to find here is the Win. ballistic silver tip wsm. I'm perfectly okay with it, but I would like to see what a different round would do. I have also found that the 130 grain does much better in my gun than the 150 grain.

RE: difference in .270 and .270 wsm
 

As far as ammo is concern Ihave beenlucky that my 270wsm likes the 150gr. Winchester Power Points at $26.00 a box. Does not really matter to me because I am going to roll my own. I believe the 270wsm will out shine the 270win when you shoot the heavier bullet like the 150gr. More velosity with a higher BC bullets means flater shooting. Berger is comming out with a .277 cal. 130gr,140gr. and 150gr. all VLD style bullets. They haven't posted them on their website yet but will soon as Walt Beger gets back in town.
