Home Forums Hunting & Shooting Hunting Rifles 270 WSM vs. 270 winchester

Hornady's light mag in 270 shoots 3190-3210 fps out of my 22" 700. It clocks in 3230 in my 24" M70.

Has anyone shot the .270/110 TTSX over a chrony?

There is precious little difference between the two and it would depend on how far away the animal was when hit, but even that won't make any difference within practical ranges..There is just not that much difference in trajectory and killing power between any of our cartridges within reasonalbe guide lines, they are all about the same, the rest is hype that we are supposed to believe...

Proper bullet construction for the velocity is way more important than what caliber we are using, again within practical boundries..

If anyone can tell me the difference in the field between say the 25-06 or 7x57 and a 7 mag or 30-06 as to killing power and trajectory, I'll eat their hat...trajectory is less than 3 inches and in field conditions that means nothing. Any of them with a proper bullet in a proper spot do the same thing..

If you want more then make a big jump to a 338 or .375 but don't expect miracles..I have seen Impala take a 300 gr. 375 or a 210 338 and run a 100 yards many times, same with all calibers.

Too much hype out there, but I guess thats what keeps folks interested...

I have and out of 22-23" tubes 3250 to 3300 is the top end range.

Dober,
Was that in a .270 WCF? I'm getting more than that out of my 130s in the .270 WSM

You've had far more field experience than I have. Are you saying that you would be just as comfortable facing a large brown bear using a 25-06 using 120gr bullets as you would a 30-06 with 220gr bullets?......................................DJ

When I read Atkinson's comparisons I concluded he was talking about deer, elk, antelope, caribou, sheep, goats and black bear.

Given Ray's propensity for 375's and up when called for,and ample doses of horsepower, I sorta concluded the same thing...

I suspect he's making a case about comparable cartridges for more common game.

I think Ray was making two comparisons. One between the 25-06 and the 7x57 and another between the 30-06 and the 7mm Mag.

You guys are correct in that I was talking deer, elk, Pronghorn, and plainsgame as I don't consider any .277 caliber a dangerous game caliber, I am sorry I didn't make that clear, I just assumed it was a given...

I don't own any 270 so I have no dog in this fight. Seems to the biggest advantage of a 270WSM over the 270 Win is the former can fit into a short action. So really all things being equal a rifle in 270WSM is perhaps a one pound lighter. That's important to some folks...

point of clarification please - is it true that the hornady light mags (in 270 win) push the same bullet as fast as a factory loaded 270wsm? not talking handloads here, just the store-bought stuff.

For info only,problem is, many of them are not lighter....even my pre 64 FW 270 Win with a Brown stock weighs about the same as a 270 WSM Montana; a Rem ti in 270 Win weighs less; and a FW M70 Classic in 270 WSM weighs more than any of them,or about what my 7 mags have weighed for 30 years.

The only rifles I've seen deliver on the lightweight advantage for the WSM is the Kimber Montana,and the Browning ti gun.There may be others,just as there are others in 270 Win that will go even lighter.

IMO distinguishing between these two cartridges based on rifle weight is as tough as distinguishing between them ballistically.

I think that the example of a 115gr bullet in a 25-06 and 220gr bullet out of a 30-06 illustrates that the IS a big difference in both Killing power (on larger game at least) as well as trajectory. Maybe a better way of putting it is that deer and antelope are not really that difficult to kill and so most calibers will kill them just as adequately as more powerful ones......................................DJ

The Remington M700 Ti WSM is 4 ounces lighter than the Win. I think the Kimber Montana's have about the same between them. All have the same barrel lengths.

Sure has been a long winter. Should just posted last years thread on the WSM's or the year before and on!

Why a company could not build a standard rifle chambered in 270WSM a pound lighter than the same model in 270 Winchester is a mystery to me.

You can't build a pound difference between the two because a typical standard action weighs in the mid 40 oz range. And a short action of the same make shaves 3-4 ozs. Then you have the barrel countour problem. Manufacturers like to put magnum countours on WSMs and standard countours and/or shorter barrels on standard .270 WCFs.
My .270 WSM is my second lightest gun, behind my .243 WSSM, but quite a bit lighter than my .264, .280 and others. It's lightness has more to do with the whole package rather than just the action length.

Thank you for your explanation. But if the reduced weight of a short action versus a standard long action is 4 ounces what is the real world advantage of a Winchester Short Magnum over what is already available? Is it "new and improved" marketing exercise?

Maybe this will help. Get the 270 Winchester! Then, ease a 338/06 or Whelen barrel on in place of the pea shooter. If you can't find a 338 or Whelen barrel just put a 30-06 barrel on and shoot Nosler 200 or 220 Partitions. That way, the girlies won't have your rifle when you want to kill a BIG game critter.
