WSM 270
I am trying to find out why a wsm 270 has less fely recoil than a 270 win?

Felt recoil is not only a product of how much powder a case holds and how heavy the bullet is that is being pushed out the barrel but also the weight of the gun and the shape of the stock. I didn't major in Physics but I have a fairly decent grasp on reality so if all things were equal ( same gun style, weight, etc.) my bet would be that you would "feel" more kick from the WSM 270 rather than a standard 270. 0 -
thanks for the reply but in an article it showed
that the short mags produce less recoil. It did not explain why.
So all the equal the wsm's are producing less i was just
wondering why. it is the same every thing except powder and size of
case. Again thanks for the reply0 -
Would you please tell us where and when the article was printed? I, for one, would like to see how Winchester has recinded the laws of physics regarding equal and opposite reactions.

one would be from shooting times april 2004 on the .25 wssm
pages 40 and 41. "preceived recoil is mild, and free recoil
energy calculations indicate a decrease in recoil compared to
the .25-06."I have also read this about the 270wsm and
the 300 wsm. I will have to find the articles becasue this is
the only one i have at home the rest are at work were all my good
reading takes place. This is true I have shot the 270wsm and
own a 270 win. I know that it has less recoil I just dont know why.
Thanks for your post but if any body knows Why I would love to hear it0 -

Last year, Winchester ammunition led the industry with the introduction of the 300 WSM (Winchester Short Magnum) the new shape of magnum rifle cartridges.
Due to the outstanding response from sportsmen and the hunting and shooting press and the award of the 300 WSM for "Ammunition of the Year" Winchester is pleased to announce the introduction of two new exciting members to the Winchester Short Magnum Family: the 270 WSM and 7mm WSM. These are the two calibers most asked for by the shooting public to be added to the WSM Family.
The new 270 WSM elevates the 270 Winchester performance to a whole new level not previously available. Fans of the 270 now have a flatter, longer range, harder hitting hunting favorite.
The new 7mm WSM easily matches the performance of a traditional 7mm Magnum cartridge. What the 300 WSM is to the 300 Winchester Magnum - the 7mm WSM is to the 7mm Magnum!
With these new WSM offerings, hunters and sportsmen will have two more exciting reasons to "go Short Magnum." Like the 300 WSM, each of these new cartridges delivers incredible accuracy and magnum energy and velocity performance in a short action cartridge all with lower perceived recoil in lighter weight rifles.0 -
THE RECOIL OF THE 270WSM IN MY A-BOLT IS A LITTLE MORE A 270 WIN
I BELIEVE , BUT NOT AS HEAVY AS OTHER MAGNUM CALIBERS. I BELIEVE
THE REASON IS THE POWDER BEING SPREAD OUT IN THE FATTER CASE RATHER THAN STACKED HIGH IN THE LONG MAG.CASES . THE POWDER DISPERSMENT PRODUCES A DIFFERENT BURN RATE ,I BELIEVE THIS COULD BE EXPLAIN BETTER BY SOMEONE MORE KNOWLEDGABLE ON RELOADING .

If the 270 wsm is anything like the 300wsm, all I can say is BULL bababooey. I have shot more than one 300wm and while a tad bit stiff all they ever did was provide a steady push. My 300wsm would flat rock the heck out of me. Both kick harder than any 300wm I have ever shot. That 270wsm should do the same thing. You are burning more powder. Regardless of how the case is shaped.
Everyone has a photographic memory. Only some have film.0 -

You are burning less powder not more out of the wsm.
As the article that I posted from winchester and shooting times
states there is less recoil and I have another where they give
measured recoil and it to is less. it has been proven that if
the guns are the same you will get more veloicty and less recoil
out of the WSM and the WSSM. If you read the post I have given two
sources that say the same and there are more out there. I have shot
the 270wsm and it had less recoil than my heavier 270.0 -
You're kidding yourself about it having less recoil, and they do not burn less powder than a 270 Win.. I handload for a 270WSM and it burns more powder and recoils worse than a regular 270. The sources you cited are just a bunch of promotional sales pitch from the sellers with the key word in the phrase being "perceived" recoil.That doesn't mean it really recoils less. More than likely you have one of the many poorly designed stocks on your regular 270 win that make the recoil worse than it should really be.-- The other comparision of the 25WSSM vs the 25.06 is not an "apples to apples" comparision. The 25.06 is a full length 30.06 case vs the Super Short case whereas the 270 WSM case holds more powder than the 270 win. case. -- The 25WSSM is also not as fast as the 25.06. -- Don't believe everything you read that these people put out as this is how they make their living. Out in the real world things are often different than on paper.-- I will concede that the 270WSM is the lightest recoiling of the WSMs if you load it with light bullets...........[8D] 0 -
try this there is less powder it is another source i think i am close to finding my answer

Just last year Winchester developed its own unbelted case--but made it short enough to fit into short bolt actions. The initial result, the .300 WSM, uses a 2.1-inch case with a slightly rebated rim of .535 inches, and a base diameter of .550 inches. With a 35-degree shoulder and a relatively short neck, the case has only slightly less capacity than belted magnums based on the .375 H&H case cut down to fit into .30-06-length actions (nominally, a case length of 2.5 inches). In practice, the greater burning efficiency of the short, fat case makes up for the slight difference in powder capacity; the .300 WSM equals the .300 Win. Mag. in performance while burning about seven percent less propellant.
This Browning A-Bolt in .270 WSM, topped with a Kahles 3-9X scope, grouped well with both test loads, turning in some very exceptional groups.
This difference alone isn't enough to get excited about. However, there are several side benefits. First, the WSM case can fit into a short bolt action, potentially reducing gun weight and bulk. Second, burning less powder reduces recoil. This is a mathematical fact, since the weight of the powder charge is one of the factors used to derive recoil velocity, which is then used to compute recoil energy. The problem with this is that, mathematically, the difference isn't all that great, while the difference in felt recoil between a .300 WSM and a .300 Win. Mag. of similar weight and feel is noticeable, so there must be some other dynamic involved with efficient ignition and burning that I don't fully understand.0 -
Thank All Of YA'LL for the help it has been fun but I have found my answer.
Thank you every much for all the input.[:D]0
