| I have read that the wsm rifles have less recoil this comes from a mag article and a 270 win and a 270wsm were measured with the wsm having less. WHY? the article did not say |
|
With the same bullet weight, at higher velocity, in the same type and weight of rifle, it WILL recoil more. This is law 03shooter I'm not looking to argue, I must confess I had the EXACT same thinking....then I bought a .300wsm. To the original post, I don't understand either but I will 100% guarantee you it recoils WAY less. My wife loves to shoot it. Yes, my wife loves to shoot my .300 mag (WSM). She won't come near my 30.06, but have to pry the .300 out of her hand. I don't understand, but I'm hoping someone can answer the question.......WHY is it like that. |

THIS IS FROM WINCHESTERS WEB SITE SUPREME® & SUPER-X® 270 WSM & 7MM WSM View Ballistics Data for 270 WSM, 7mm WSM, and 300 WSM View Reloading Data for 270 WSM, 7mm WSM, and 300 WSM 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. |
I have to agree my .300wsm model 70 feather weight seems to have less recoil than my 30-06 and 300 win mag. The .300wsm was the best purchass i've ever made.. |
| All the mag articles I read all say that the wsm and wssm have less recoil. shooting times has one out for april on the .25 wssm that also states this and it states that they have less recoil on winchesters site as well. that is the long post i have here. None of them say way. there is also a article that states they have measured the recoil and it is less i cant find it but when i do i will post it to. All I wanted to know is why? |

As other members have advised the laws of physics cannot be suspended. Same rifle weight, same bullet weight and a higher veliocty will generate more recoil. There are numerous software programs that can be used to calculate the recoil using a number of variables and the recoil figure is usually expressed in pounds. However, another member pointed out what Winchester placed on their website. It did not say that recoil was lower it said lower perceived recoil in lighter weight rifles and I believe that statement is meant to address the recoil impluse. The recoil impluse is the amount of time over which the recoil is transferred. At extremes the recoil impluse can be very sharp and quick or it can be more of slow push. The only analogy that comes to mind is how people refrence the recoil if the 45 ACP as a push while the recoil of a 10mm is like a hit. Manufacurers have worked to minimize the "felt" or perceived recoil especially as the magnum race continues. Development of recoil pads to better manage what the shooter feels continues to progress. Think of it like this, would you rather have 12 lbs of recoil hit you in the space of a nail head (small surface area) or a larger surface area? That very thought is what leads recoil pad development. Getting back to the orginal portion of my post, nothing that the manufactuers do changes the laws of physics. 12 pounds of recoil is 12 pounds of recoil. However, how the 12 pounds of recoil is delivered to the shooter makes a difference in what the shooter thinks. There is also a lot of shooter capability and technique involved as well. There is a website that shows video clips various people shooting a 577 T-Rex which generates over 100 pounds of recoil. One person that was obviously a shooter locked the rile into is shoulder and had a forward stance and shot the rifle with no problem. The other people shooting obviously have no idea how to shoot and get knock over or drop the rifle. Here's the website www.accuratereloading.com/videos.html Watch the video of "Klaus shoots the 700 NItro Express," then watch most any other video at the site of people that don't know how to shoot. Bottom line - it is all how recoil is managed. |

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." there is less recoil out of wsm. Again I have shot a 270 wsm and had less recoil. the liter the rifel the more recoil felt that would be the law of physics. the heavier rifel would abssorbe more energy than the liter one. http://www.gunsandammomag.com/ammunition/short_magnum_trifecta/ |

OK G&A mention free recoil is less with the WSSM than the 25-06. IMO from the ballistics charts I have reviwed the short magnums never really match up to their long action equivalents in terms of power anyway. The manufaturers marketing disagrees with the statement I made above, however other articles I have read support this position - unfortunately I cannot quote a specific source for you to read at this moment. If I can find it I will edit post in future. Anyway, in the article I reference the tester chronoed the short magnums and they never met the manufacturers claims of velocity. I feel this pans out in what G&A tested - did the article chrono the rounds from both and how close were they in velocity and were they using the same weight bullet? If the velocity is lower in the short magmun, then free recoil will be less. I also looked at the Winchest site for the 2 loadings and they are the exact numberas across the board like they have been cuit and pasted from to another. Normal variations in testing would cause some difference in the numbers. As the saying goes it takes powder to make a bullet fast and case capacity is the limiting factor. If you want to fast get a bigger case. |

this is a part of the guns and ammo article it is to the link that i put at the end of a qoute from shooting times on the .25wssm. This art. covers the 270wsm and 300wsm and 7mm wsm. I have learned a lotfrom this but would like to have a little more hands on, but as you read the article youwill find that the wsm does equal the longer counter part on all calibers. I know that you cant believe all you read but I have yet to read anything that says these rounds produce more recoil. 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. |

Less powder produces less recoil. Here is an explanation of why. Because the WSMs burn powder more efficiently, they have less recoil when generating the same energy. That is why the 300 WSM has slightly less recoil than the 300 Win even though the muzzle energy is basically identical. The 270 WSM has more recoil than a standard 270 though, because the 270 WSM has quite a bit more velocity (225 fps). If the velocities were the same, the WSM would recoil less. |
I have the 300 WSM in a Browning A Bolt Medalion, and it beats the hell out of me. My 300 Win Mag is a Model 70 Winchester, And I can shot that rifle all day. |
