And 700 yards is only for freaks so it doesn't need to fit anywhere ;-)

Blimey, so is 25-100m "point-blank"?

A .308" round's still climbing at 100yds, isn't it?

Thanks Laurie, I wasn't aware short range was defined officially.
A couple of my clubs run "mid Range" shoots which are usually 300~500 yards hence the answer.

Depends what angle you launch it

A round never climbs it is always dropping. (Or level if fast enough ) You sights/angle/elevation is what makes it go up, bullets do not travel in arc like folk believe!

Can you please explain, as I don't get this?
A bullet is always dropping in the sense that it is always accelerating downwards at 9.81m/s^2 once it exits the barrel, is this what you mean?

Gaz,
the other Gaz said that the bullet would be still climbing, I pointed out this is not so. Now rounds like the .17hmr are fairly flat (yes technically still dropping ever so slightly) but NO bullet goes up, unless you aim up! The angle between the sight and barrel is what people confuse for the bullet going up. The misleading arc shown on some graphs does not help.
Mkke.

Ah, I think I understand what you're saying now...
If you point a firearm so that the barrel is horizontal and fire a round, then the bullet never rises beyond the line of the bore because gravity acts and there is no lift.
However hitting a target at any distance appreciably beyond zero involves setting your sights so that the barrel is pointing slightly upwards, so the bullet does climb (before dropping back downwards, depending on the distance, muzzle velocity and BC of the bullet.)
Is this what you're trying to say?
