Well, if we're going to go all metric and stuff ... 10.9x29R .

What? No love for the 5.5mm Velo-Dog?

bigdv · Jun 28, 2017

Definitely 40!

bigdv · Jun 28, 2017

Wait..... i mean 9 mm!

Mark II 12 mm rocket now that space corps is a thing.

For a new shooter, 9mm probably a better choice. All things being equal, the 40 tends to have more felt recoil and muzzle flip.

Wow. How loud is that? Probably not verry good ballistics for a 223.

9 vs. 40 vs. 45?

When you think about it the question can be easily answered mathematically. For example:

45/40 = 1.125
1.125/9 = 0.125
0.125 - 0.0309 (the inverse of the frictional coefficient of Alox lubed boolits vs. FMJ's)= 0.09410
0.09410/Pi = ...you guessed it... 3%

Of course there is a much easier formula that clearly defines the answer:

5 X 9 = 45.

:rolleyes:

Just to confuse the OP: With a 357 you can also shoot 38 spc

If the bullet doesn't get them, the fireball will.

Yeah, best guess is the performance would be roughly that of a 5.7FN

More case capacity, but slower burning powders. Now if you loaded up a cartridge with pistol powders for that like .223 handgun...

No matter what, it would kind of suck.

On the .50BMG handgun... :wtf:

I'd imagine even with the big comp that would be likely to break wrist bones.

I go with 9mm.

Why?

Easy. Because I am not one of the people in the room professional enough to use the .40
