Re: Muzzle brake on a 300 Win Mag?

The recoil energy caused by the acceleration of the bullet is only about 1/2 or even less than the total recoil energy. and it is by itself not a measurement of felt recoil or recoil by itself for that matter. There are a lot of very simplistic definitions found on such things as Wikipedia and brief articles here and there and they are not intended as an education on a subject, they are a basics primer to satisfy a little bit of curiosity. I cant actually say that you are wrong but that the understanding behind it is. I will give one very good example many have a Barnes #3 reloading manual and many have a 300 RUM ( page 414 ). look at the bullet energies you will notice that the 250, 220, 200 grain bullets all have less energy than the 140, 150, 165, and 180 grain bullets. What does bullet energy have to do with recoil, it is called conservation of energy or an impossibility of getting more energy out of a bullet than what you put into it. and if you take a quick glance at the average charge weight differences there is perhaps 20 grains difference of weight and that gas produces the other half of the recoil energy as it leaves the barrel. in this small and verifiable list the heavy bullets all by themselves without gas weight velocity energy is far less than the lighter bullets now add that extra 20 grains or so. Absolutely heavier bullets produce less felt recoil. As far as gas density I do not think that you will have to go too far to find a pilot and ask him what effects just plain old air density has on his airplane and it is nothing more than the energy too lift. A very good and very simplified Wikipedia explanation might be this: E=PAT or Energy is a product of Pressure area and time for the rifle and it has a responding felt recoil

I don't know anyone that will agree with you on this. I know my .416 Rem. Mag kicks considerable harder (felt recoil) with 400gr bullets then 300gr bullets and my .458 Lott with 300gr bullets is a pussycat compared to 500gr bullets. I think what you are trying to express is recoil velocity and not recoil energy. Both effect felt recoil but recoil energy is what people complain of more and if you look in the physics equations in the link it's pretty easy to show primary recoil is higher with heavier bullets.

Re: Muzzle brake on a 300 Win Mag?

Have you considered a suppressor? They are legal in many states for purchase and in a number of states for hunting. I have had mine for about six months (Thunderbeast 30p-1). It makes it so much more pleasant to shoot compared to nothing (more recoil/noise) or a brake (extreme noise/blast). I still wear plugs when target shooting but it provides hearing safe numbers while hunting with no ear protection. I plan on deer hunting with mine this fall in TN. I personally find it easier to spot hits with a suppressor than a brake. I have a brake but never use it anymore.

It is very nice for introducing shooting to neophytes. A much less intimidating experience when it sounds like a .22LR vs a cannon! Worth the money and the wait.

Re: Muzzle brake on a 300 Win Mag?

I'm new to the power, and recoil, of the 300wm. I have two rifles, 9.5# and 7.25#. So far, I've only loaded hot 180gr loads and pretty pleased with the handling of both rifles. I will be testing some 210gr Bergers which could change my vote to "seriously thinking". I've been hunting and shooting fairly stout 45-70 loads for years. The 300wm is snappier, but much less punch than the 45-70 with 350gr and 400gr bullets.

Re: Muzzle brake on a 300 Win Mag?

I took it one step further and added a 16oz recoil supressor to the buttstock of my rifle, as well as a break.
I'm not recoil shy but I do have disk problems in my neck and they don't need undue agrivation.
My 300WM I only use for stationary hunting too so I don't care what it weighs, currently it's 13.25lb unloaded.

I have a .300 win mag and I have a que industries adjustable muzzle brake on it. It shoots pretty well and the brake kills about 40 percent of the recoil.

The bottom-line, something has to give ... the weakest point (i.e., stock, etc).

As far as developing good shooting technique, I find it difficult since I cannot get a good consistent check weld and LOP. After I am satisfied with my load, I switch to the bags.

Just my thoughts for your consideration. Happy safe shooting/hunting.
Get yourself an empty old shot bag. Fill with shot, sand, gravel whatever is handy. Tie it off well and use a piece of trotline cord tied to it, run through your front sling swivel and tie it to the front of the trigger guard.

Hang the bag off of the front of the bench with the bottom just resting against the ground.

That eliminates most of the felt recoil of most weapons and eliminates the need for something like the lead sled which allows you to assume a normal shooting position.
