I think he's saying that the gun is sighted in for 300 meters and it has a built in elevation switch on the sights.
Shooting high at 100 meters is typically considered a good thing because this helps at point blank...people usually start pulling the trigger too early as they pull up the weapon and this helps less bullets hit the ground in front of their target. Plus the bullet hasn't had far to go at this range so it is not far above the where the sights are pointed. Unless you are squirrel hunting a rise of even 5cm at 100 meters is considered spot on most of the time. When you have non-adjustable sights this is always a given.
At 200 meters they are forcing the gun to shoot low...probably just a side effect of how the scope or sights are attached or else some one deemed it a good idea to shoot a little low at 200 meters...I know the F88 has a mean trigger pull on it as compared to other weapons. I don't think the gun even needs a safety. That trigger isn't getting pulled by mistake. At 200 meters soldiers are probably more prone to panic a bit and not focus. The hard trigger pull in a bullpup design might cause them to shoot high more often so they compensate it in the sights. However, a bullet is ALWAYS dropping. They are shot up in the air and gravity pulls them down. So if it is below the point of aim at a midpoint trajectory it done so on purpose by the firearm's design and configuration. I have seen this in other firearms so I know it happens.
At 300 meters...the sights are at their "natural" zero'ed in position. And building off what I said above at this range people tend to be more relaxed as they are pulling the trigger...their target is just a small dot at this range. So the trigger pull probably doesn't hurt things much.
At 400 meters it makes sense that the bullet is far below...there probably isn't a setting for this as this is the max effective range of the F88 which is considered to be a close quarters weapon. It would be like shooting a M16 at 800 meters. You have the ability to hurt a target but it is unlikely you will hit them.
Or they could just be wrong, but I'd hope an aussie knows the capabilities of their own country's weapons. Bullets rise because they are shot up in the air and from there they are always dropping. if we didn't do that they would not be hitting much that was even at medium ranges.Edited by Vagrant Storm - 9/25/13 at 8:50am
