If you shoot a moose with a 308 warbird and a hard 180 grain expanding bullet at 3500 f/S.

And if you shoot a moose with a 577 T-REX and with a 750 grain expanding bullet at 2500 f/s.

What of these would do the biggest damage in the moose...?

The 308 warbird is fast but does it do the explod effect and a bigger hole than the bullet expanded diameter...?

The 577 T-REX have more energy and bigger expanded diameter but does it do the explode effect like the fast 308 war bird...?

What of those is most deadly...?

You guys know that i want to learn the terminal ballistics...! so please give me real answers...?

Do read this:

(Another special thanks to Harald for providing this very interesting site!)

I have read the Terminal Ballistics---Cavitation.

Hydraulic pressure, or the splash effect causes damage from the pressure front extending from the outer edges of the bullet.

And that will do a much bigger hole in the animal than the expanded diameter.

But what will do this...? high velocity or energy or what...?

What will do a bigger hole a 308 war bird with velocity over 3500 f/s with 180 grain bullet, or a 577 T-REX with lesser velocity but much more energy....?
