Hello,

Is there much difference in recoil with the .460 S&W and .500 S&W?

Model of guns:
.460 Model 4" barrel w/ compensator
.500 Model 4" barrel w/ compensator

Ammo used:
Hornady Custom Ammunition 460 S&W Magnum 200 Grain Super Shock Tip
Magtech Ammunition 500 S&W Magnum 400 Grain Semi-Jacketed Soft Point

From my experience with the 460 and what I have read on the 500 yes. There is a noticeable just in the 460 going from the 200 grain SST to Corbon 395 grain. Pushing a heavier bullet is going to give more recoil so to tell the difference between to the 2 you really need comparable bullet weights. Just my .02.

envonge, dejr2000 is right the bullet weight is your big factor. If you double the weight of the bullet, you will get 4 times the recoil. I have the 460XVR, and I shoot it with the lighter bullets and the recoil is not objectionable. (I'm 60+, 5'7" and 158lbs).

I've thought about getting the 500, but doubt if I'd shoot it enough for it to be worth it.

I have a 460 with the 8 3/8" barrel and shooting the 395 grainers definitely doesn't feel like 4x the recoil of the 200's. The 395's seem to have less muzzle flip but do hurt my hands a slight bit more than the 200's.
As far as recoil, my 460 has very manageable recoil and doesn't bother me much at all but anyone who has shot mine at the range seems to think otherwise.
I've never shot a .500 so can't compare the 2.

XD 460, there is a big difference in felt recoil vs measureable recoil i.e. you can have fantastic grips that greatly reduce the felt recoil, but the recoil is still there. Here is a quote from another web-site on the topic: (it is okay to copy from another web-site as long as it isn't copyrighted - correct?)

I'm still bothered by experience vs. theory, especially what I read concerning the new S&W 460 XVR. So, I bought a new book Understanding Firearm Ballistics by Robert A. Rinker ISBN: 0-9645598-4-6.

A few excerpts from the book:

"Recoil increases as the square of the velocity". Well, we knew that.

"Recoil also increases as the square of the bullet's weight."Whoa, this is big news. I thought it increased only to the first power. Now what people have said that they felt shooting the heavier bullets makes a lot of sense.

"But, it decreases only to the first power with the gun's weight so a change in the gun's weight has much less effect."

The formula he gives for Recoil Energy is:


RE = 1/2 GW (bw*bv +cw*C/7000)2
Where:
RE = Recoil Energy in ft.lbs.
W= Weight of gun in lbs.
C= Constant (4000 f.p.s)
G = Gravitations constant (32.17 ft./sec./sec.)
bw = bullet weight in grams
bv = bullet velocity in f.p.s.
cw = power charge weight in grams


I also thought it was interesting that he said the weight of the powder charge has to be considered in the recoil energy.

"High velocity .22 centerfire cartridges, such as the .22-250 , will receive as much recoil from accelerating the powder charge as from accelerating the bullet."

He also mentions that the average person can handle 15 ft. lbs of recoil without discomfort, which is what we get from shooting a .44 Magnum with a 240 gr bullet and 22.5 grs. of charge out of a 3 pound gun.

What I find interesting is the .357 Magnum with 158 gr bullet in a 2.1 lb gun has recoil energy of 10.1. Okay, doing the math on the S&W 340PD with its weight of 12 oz. gives us a RE of 27 ft.lbs. Now I understand the remarks people have made when shooting this gun that usually start with the word "mutha".

Well, I'm not sure I understand all this stuff, but it is making more sense, and follows in-line with what some people have experienced shooting heavier bullets.

I have shot the 460 (8 3/8") with the standard 200gr hornady loads, and it was a pussycat. Lots of flash and boom, but the recoil was very reasonable. Not painful or even jarring at all.

I have shot the 500 (also 8 3/8)", but only with fairly light reloads- bullets were I think 360gr or so. Even though they were light loads, there is still a big push from these. I'm sure it is quite a thump, likely painful with the bigdaddy loads.

The load I shot from the 500 was much more pleasant to my hand than 454 form a 7.5' SRH. And the 460 felt like a 38 compared to the 454. No ****ting.
