Yes sir, I understand all of that. But, since the original post said he was looking at a Weatherby Vanguard Synthetic/Stainless, which is chambered for all three of the cartridges being discussed, I thought that the variation resulting from stock design would be eliminated. You had said there were four different constructions of Vanguard stocks and I was asking, since I don't know, whether you meant that there are multiple constructions of the synthetic stock. Not trying to be argumentative, just trying to learn...

Those are the 4 different stocks they can be sold with

All i can tell you is, i had two guns exactly the same, one 300 Win. mag., and the other 300 Wby. Mag.. And the Wby. had more felt recoil with the same weight bullets...

I don't know about the other 300, as i've never had one, but i'd bet the Wby. will have the most recoil...

I'm not sure how it relates, but Hodgdon' web site shows that using the same brand powder (H4350) and the same bullet (180gr) these three cartridges develop the following:

powder charge FPS Pressure

300 WSM 64gr 2950 63,900

300 Win Mag 67gr291853,100

300 Wby Mag 72gr 2974 54,600

There must be something about the case designs that causes such significant differences in burn rate to have this much effect on pressure.Muzzle Energy should be close to the same given equal bullet weight and close to equal MV. So is the difference in recoil related to time ofacceleration?

My ratings were what they felt like to me...purely subjective. I stand scientifically corrected as necessary. I have not shot an Ultra Mag, but my comment was based on a friends observations. Next time I'll just shut up.

In the same rifle......id be pretty certain it would be the Wby followed by the Win Mag, next the WSM, most kick to least....

Call him"she" and he's liable to knock a lung loose for ya.........

Noone here are talking .243 talk, but if you want to...we can..............

There are four majorfactorsthat go into the formula for computing recoil: Bullet weight, Powder weight, muzzle velocity, and weight of the GUN! Case size and shape have no influence on recoil whatsoever, (except insofar as these factors might affect the muzzle velocity possible from a given weight of bullet & powder.)

IF rifles in all three were to fire the same weight of bullet at the same MV, and all three rifles weighed the same, the round using the heaviest powder charge would give the most "FREE RECOIL". However, this doesn't mean that that rifle would feel the worst to the shooter. Stock shape, etc., has quite an influence on how bad the recoil FEELS.

Any change in the makeup of the roundfired will also affect how much the rifle recoils. Lighter bullets give lower recoil, as will alower powder charge and a lower MV - and vice-versa.

Overall, I would say the .300 Weatherby will generally have the most recoil, (as it usually uses MORE powder to get a higher MV with the same bullets) the .300 Win. will be next, and the .300 WSM the least.

BUT, if you want to know for sure, weigh the gun, pull a bullet from a given round of ammo, and weigh bullet& the powder charge. Then fire a few of the rounds, and determine their MUZZLE VELOCITY! Then plug yournumbers into this formula - it will tell you the actual recoil of that gun and load!

That is my opinion as well. The fact that the powder type here is constant is a big help. Lots of factory loads use different powders for different calibers. The way the powder burns has a lot to do with what kinda whallop you are going to get out of a gun.

I'll tell you right now that a faster burning powder is going to punish you more. Anybody reload shotgun shells? I remember being a youngin' and shooting some fast buring 20ga buckshot my father loaded out of my light double bird gun and wishing I'd never taken up hunting. He went back and used something a bit slower and I could shoot all day and not bat an eye. Velocities were nearly the same, payloads identical... there is something to burn rates and case designs.

That was an accident... not intentional.

That's just plain funny right there.

I always like talking about .243s...
