Heavier bullet = less recoil?

[BADUNAME37]

I shot some 440g bullets from my 500 Magnum (4" barrel) and some lighter bullets. The 440g were so punishing, I thought I could possibly fracture my wrists, arms, etc.

I realize that comparing different cartridges from different manufacturers is akin to comparing apples and oranges.

I should have Chronied the loads, then I could have done the calculations. Without the bullet's speed, we know nothing other than how they "felt."

I can tell you that the hard-nose 440 Cast went through 14" of solid Poplar Tree and just stopped as it was exiting the opposite side! Frankly, I was impressed!

If you've got a 500, look for the shortened version of the case, the .500 JRH.
You really don't need more then a 430-440 at 1350 fps. Kill anything, dead.
This is around 40 ft-lbs of recoil in a normal gun, probably 30 ft-lbs in that giant X frame.
EASY to shoot.

I'm getting a .500, and plan on using 440's at 950 fps for plinking, and, 430's at 1350 fps
for anything else. These are the stock loads by Buffalobore for the .500JRH.

Lets say the bullet weighs an ounce and the gun weighs 32 ounces
the velocity of the bullet is 1000 ft/sec.

Think about it. One bullet weighs 1 oz. and another weighs 2 oz. but they both travel 1000 ft/sec. it's going to take a bigger bang, for the 2 oz. bullet, thus more recoil.

Yes, but we're talking about bullet weights within the same cartrige. In a .40, for example, 180gr bullets recoil less than 135gr bullets when each is loaded to the maximum velocity permitted under the 35000 PSI max pressure limit.

A 180gr bullet at 1000 FPS recoils less than a 135gr bullet doing 1400 FPS.

We are not talking about 180gr bullets and 135gr bullets doing 1000 FPS.

why does one recoil more than the other? Because they do.

See post #14. The 135gr load has a higher momentum and reaches that momentum faster than the 180gr load. Since momentum is what you perceive as recoil, the load that reaches peak momentum faster will recoil more.
