Would this 6# .338 Lapua kick more or less than a .458 Lott in a 9.5# rifle?
Hmmmm, how would the recoil on this puppy compare to that of a 20mm Solothurn?
Ha! I missed this thread the first time around...
Worst rifle I've ever shot was a 300 Win Mag that I think weighed just under 6 lbs with the scope... No brake. One of the custom builders like Brown but it wasn't a Brown. Now, I'm not what I would call recoil sensitive. I've shot most reasonable cartridges but this thing... The 300 was just so fast of a jolt, plus not only to lightweight rifles not absorb the recoil, they don't slow the recoil velocity down as much as heavier rifles. I don't think I have any eye damage but when I shot it, it felt like my cheek had frostbite and everything went red for probably 10 seconds. I don't think I opened my eyes for a couple seconds, but when I did, everything was red. I blinked a couple times and colors started coming back to where they should be. It was a really nasty experience.
I think I remember reading in one of the gun rags (might have been written by Boddington) about someone just starting out in the Marine sniper training. There was a 50 available and someone was talking about the recoil of it with the muzzle brake. The guy said he would shoot it without the muzzle brake and proceded to do so... Prone! Pushed him back against the ground a couple feet, broke his collar bone... couldn't finish sniper school and whoever wrote the article said that as much as they put into these guys, even if he could have physically completed the training, they probably wouldn't have let him. They train these guys not to do stupid things and that was a very stupid thing.
A 338 Lapua in anything less than probably 9 lbs would be just about intolerable in my book and I agree that it would probably be worse than an 11 lb .577 due to the speed of the recoil. That's definately a rifle that you will want to bore-sight before going out because unless it is braked with a very effecient brake, I can't see anyone being able to put more than three rounds through it in a day. I guess you could get about six shooters together and each takes a shot and then makes the adjustment...
This is truly a thread to use this smilie ----->
Dude, don't shoot it.
"The guy said he would shoot it without the muzzle brake and proceded to do so... Prone! Pushed him back against the ground a couple feet, broke his collar bone..."
I'm actually sort of surprised that it didn't collapse the shoulder socket and pneumo-thorax his stupid behind, too.
The simple fact that he shot it prone, instead of upright from a bench, may also have saved him from a serious neck injury, possibly even death. The neck can take a lot, but that kind of rotational force is a little much.
There's a reason why there are muzzlebrakes on .50s -- because they generate over 6 TONS of energy at the muzzle (military .50 BMG loads are in the 12.5K ft. lb. range).
just curious....whats that convert to in terms of recoil?
According to the calculator on Handloads.com, and guessing on a few things:
Bullet weight - 720 grains (Ball M2)
Velocity - 2810 fps (Cartridges of the World)
Powder Charge - I'm guessing here, but I figure a case that large, 120 grains?
Weight of firearm - Another guess, but I'm throwning in 20 pounds.
That calculates out to a free recoil energy of 99.28 ft. lbs.
That sounds low to me, but I just ran a 150-gr. .30-06 at 2900 fps. with 51 grains of powder in a 9 pound rifle and it returned 14.4 ft. lbs.
with a 750 GR. bullet from what i looked up on a reloading chart 233.0 grains of H50BMG powder gets you 2800 fps....
233 grains of powder!!! lord that numbers gotta be low....
230 grains of powder?
That is going to make a BIG difference...
Just under 140 ft. lbs. free recoil energy.
That's a lot more along the lines I was thinking.
"Am I nuts?"
Only if you shoot it. If you do, there should be a musical accompaniment, and my suggestion is "The Masochism Tango".
The brakes however, with so very much powder to work with, do quite an effective job I am told, eating over 70% of the recoil energy.
That brings the .50BMG back down to 28.2lbs of recoil energy in a 30lb rifle, not too shabby at all for one *hell* of a whallop, at any range. .30-06 is about 20ft/lbs of recoil in a 9lb rifle.
Make sure that brake is on there tight
Oh, also from: http://www.chuckhawks.com/338_Lapua.htm
Note this is a MUCH heavier rifle (that 3lbs matters!)
My clavical hurts...
That pretty much sums it up. Could you make a movie of your results and post it on the internet? Maybe do it in black and white so the blood won't offend the kiddies.
Remember that the pleasure from being able to show the video to your friends while you're recouperating in the hospital will only last a short while, but stuff like detached retinas tends to be permanent...
I was figuring a 20 pound rifle in the computations that I made. I've NO clue what a .50 BMG rifle weighs.
I shot one many years ago and remember thinking that the recoil wasn't all that bad for what the cartridge could do, so you're right, the muzzle brakes work like troopers.
Hmm, the original poster hasn't gotten back to us. Maybe the bloodhounds are out looking for bits of his shoulder?
He's still posting here with or without shoulder.
There will most definately be a video clip outt this.. I don't know when.. and I'll be certainly wearing my heavily padded and armored motorcycle jacket.. it's got enough on the shoulders to help out .. and if I go down the plastic plates will help out a lot ;-)
I *knew* there was a reason...
I passed up buying that Colt Light Rifle in 7mm Remington Magnum. Ouch.
I was kidding about wanting a video. It still makes me cringe to remember the one with that little Pakistani guy testing the elephant rifle. He probably never recovered.
You need to take this s*** seriously. A guy can have permanent injury to the nerves of the neck or bleed to death from internal injuries if they tear the blood vessels that go to the shoulder.
Dude, you'd have to be brain dead to shoot that thing!
I had to bring this back up......any news on this gun/shooter?
I predict something along these lines
I think it will look more like this: http://www.serveroptions.com/humor/40.mpg
If I can't kill it with a 338 Win Mag I don't think a 338 Lapua will help.
That was the one I was looking for.
The fellow with the bloody nose got a new respect for firearms.
