500 Magnum Ammo

[maineultraclassic]

I was looking at Wikipedia at the 500 magnum page and it had this in it -

The Model 500 can fire a bullet weighing 350 gr (22.7 g; 0.8 oz) at 1,975 feet per second (602 m/s) generating a muzzle energy of over 3,030 foot-pounds force (4.1 kJ) and a momentum of 13.7 Newton second.

Anyone know what manufacturer makes that round?

Thanks

Typical Wiki article, references not required

.500 S&W Magnum - Wikipedia

Just a note though, Kinetic Energy is not what makes a bullet lethal it is shot placement and bullet construction.

Shot you gun some before you jump off the deep end.

If you are not hand loading you should be.

Sorry I could not be of more help.

Good Luck and be safe

500 S&W Magnum 350 Grain Xtreme Penetrator advertises 1850 fps.

500 S&W Magnum 350 Grain XTP Jacketed Hollow Point advertises 1912 fps

The round I want to get a box of is 500 S&W Magnum 700 Grain Lead Wide Flat Nose Gas Check, but it only comes in at 1200 fps

Out of a carbine barrel such numbers are valid.

Those velocities are certainly achievable in the longer barreled 500 Mag as Hornady says 1900 fps for their 350gr load. If you use the entire cylinder length and seat the slug out to a longer COAL as John Ross does, 3000+ ft lbs is not at all uncommon.

Other than bragging rights, it is somewhat academic. The 500 Mag has penetrated Cape Buffalo nearly end to end even after breaking a front shoulder. How much penetration do you need?

The gun will easily take any animal on land with plenty of power reserve, not a stunt with guides ready to drop the animal. Don

Not the case 300grain FTX @2000 fps out of 7.5" Barrel
and 350 XTP MAG @1825 fps out of same as above and another 150 fps out of my 10.5"
I get 2400 fps out of my 22" Bighorn lever gun
This with pressure ceiling of 55kpsi.

Short seating bullets adds a few more grains of powder capacity and you can get almost 200 additional fps out of a 350 if you really push it.

As Don stated "why push it -bragging rights?" since at reasonable loading a 350 to 440 grain bullet gets more than enough penetration to take the largest prey.

Good luck
