    I was just wondering how a 300wsm is compared to a 30-06 recoil wise? I have owned a 30-06 for year's and was thinking of a new hunting rifle, I was really interested in the 300wsm so any info would be great.

  3. The .300WSM has a bit more thump to it than the .30-06. If you install a good muzzle break you can have it kicking less than a .30-06 without a break - just make sure you wear hearing protection when shooting it, cuz it'll be loud.

    Usually about 35% difference when shooting the same bullets when compairing the 300Win mag to a 30-06. I personally think it's closer to 30%. The WSM case will be higher yet due to more square inches of area being pushed into the bolt head with similar chamber pressures.

    being as the best brakes seldom reduce felt recoil more than 25%, what brake are you refering to?

    Sorry to disagree, but there is nothing about cartridge dimensions that affects recoil. The important factors are rifle weight, bullet weight and velocity, and weight of powder charge.

    About 4 years ago I spent a morning sighting in my Savage 110 in 270WSM as well as my Rem 7400 in 30-06. The Savage had a recoil pad from the factory and the Rem does not - but it's a semi-auto so how bad could it be, right?

    After about 20 rounds each I much preferred the 270WSM to the 30-06, probably due to the recoil pad. I never found the WSM to be a problem to shoot.

    think about it a minute. You have the same bullets from similar weight rifles at similar chamber pressures. The first thing to recieve rearward thrust is the bolt head. The push to the rear is identical to a hydraulic cylinder, but with gas pushing against it. The more square inches of area, the more power it has to push with. This is confirmed in Stewart Otteson's book, as well as in Bob Greanleaf and Fred Barker's writings in Precision Shooting. Otteson is often regarded as the single most knowledgable source for bolt action rifles out there. Barker is a metalurgical engineer (may have an M.E. degree as well), and Greanleaf is a well known and respected designer of firearms. When any of these three speak; people listen.

    gary: It's not about psi or bolt thrust, it's the bullet and hot gases going one way and the rifle going the other. Look at any recoil calculator. Recoil is calculated based on the weight of the rifle going one way and the weight and speed of the bullet and burning powder going the other way.

    The head of the cartridge case could be two ft in diameter and it won't make a lick of difference.

    I had a Remington model 742 woodsmaster in a 30-06 and hated it, so i gave it to my little brother and bought a Browning A-bolt 300. wsm. I was use to recoil due to owning and shooting a Remington BDL 7mm rem mag so i wasn't expecting much more. The 300. wsm kicked a little more then my 7mm rem mag but not a really noticeable amount. You could definitely notice the difference between the 30-06 and the 300. To me, anyone who shoots an 06 can shoot the 300 wsm without and issue. Hey im 17 and theres no problem here.
     
  11. I've shot .300wsm's with brakes that felt like substantially less recoil than stock .30-06's. A lady not more than 5'2" and 95 pounds brought one up all decked out with a fancy break, claiming it kicked comparable to a .308. I didn't believe her until I shot it. I'm not new to this. That's scientific enough for me. Considering what you've paid for my input, I'm confident you've gotten your money's worth. ;) :D

    I've got a 300WSM in a Remington 700 CDL.The recoil isn't too bad with the factory pad and really I do not see that much difference in recoil shooting it and my 30-06.So if you can handle a 30-06,the 300WSM shouldn't be a problem.A good recoil pad does make a difference when shooting any gun that has recoil

    the question was about felt recoil between a mag case and a standard case. One would assume they also were using identical bullets with identical chamber pressures to even begin a serious compairison.
    When the bullet enters the barrel it automaticly starts relieving built up pressures in the case in an inverse proportional square (in otherwords there is more volume in the cylinder to be filled by a specific volume of gas). But as the bullet strikes the rifeling there is a like reaction in the opposite direction (there's actually several reactions going on at the same instant). This the start of felt recoil generated from the bolt thrust. There will also be a thrust generated from the recoil lug, but one has to assume they are both identical in the two rifles. The only thing different is the area of the case head in the two rounds. Physics 101, or better yet Applied Mechanics 100. The volume of the case means little if the chamber pressures are similar, and the case head becomes the piston in a gas cylinder pushing to the rear of the reciever

    Think of it in another way. You have a piston with 2 sq. in. of area and 100 psi pushing against it. Now you have another with 4 sq. in. of area, and the same pressure on it. The larger piston will have twice the force than the smaller one will. But if you cut the pressure to 50 psi on the larger cylinder you will have identical working forces. Doubt it? Call up a local hydraulics distributor and ask him.
