Bigger round, more powder=Better stopping power/takedown power when hunting.

Because one bullet is bigger? Jesus even a no guns can figure this out if he paid attention to middle school physics.

Obviously the wind will move it less. And it delivers more energy. And travels a longer distance.

>>30606472
Fire both at a range, you'll figure out the difference very quickly.

308 has more mass than 223, ergo it is more prone to keep doing as it do rather than fall prey to the suggestions of wind and friction.

What is Physiks

Baby don't integrate me.

Why are you acting like a know it all cunt? Just answer the question without the attitude.

Sectional density.

>>30606570

So a 338 federal would be better at range than a 6.5x47?

Why use 5.56 instead of awesome manly 7.62? Only a woman or a child whines about weight and recoil.

They don't have the same velocity...

And 556 out of an m4 is like 1200

You said it yourself, you asked a dumb question

>>30606649
Cause you asked a stupid question and you got called stupid in the answer, stop being a stupid faggot and go back to summer school you can get out of the fifth grade. And I'm not who you replied to.

>>30606472
Because that is what is normally used, or was for the last 50 some odd years. the 6mm race is starting to take over tho.

5.56x45 is great for precision as well tho, tho the max effective range is a tad shorter than the .308/ 7.62x51 and it has a harder time with Wind, which at longer ranges is even more pronounced.

Why do you ask anon? looking into getting into the long range game or the precision game?

>>30606472
Basic mechanics.

You throw a 1kg stone from catapult with the speed of 100m/s

Then you throw 10kg stone from bigger catapult at 100 m/s.

Which one will de-accelerate faster?

Ballistic coefficient, OP.
Watch tibobobobosaurus rex's sniper 101 series and learn much.

>>30606472
the distance at which the bullet goes sub sonic is important
as sound waves catching up to the bullet can disturb its movement

there is also another trade off
a higher velocity gives cross wind less time to act on the bullet
but a lighter bullet will be more easily moved from its path

kinetic energy = (1/2) * m * v^2
This means that doubling mass doubles the kinetic energy, while doubling velocity quadruples kinetic energy

>bullet is bigger
>therefore is heavier
>therefore by simple ballistics it can travel longer and has more "punch", i.e. hits faster, i.e. longer effective range

bait.

This, and 556 is a fine hunting round, for medium game, with the right bullet, within 400 yards.
