40 Yard Droop!

Having read that now I know that you're a know it all dickhead that hasn't got a clue what he's talking about! Go off into lala land sam and enjoy your everafter make believe fantasies. Total prat!

 

Er numb nuts, try reading it, this explains what happens and why the pellet is rising when it leaves the barrel!

 

"The sights are placed on top of the barrel so the bore is actually below the line of sight. If a scope sight is utilized, the bore may be as much as an inch and a half below the line of sight. In order to make the sighting error as small as possible, the sights are arranged so that they are aligned on the target with the bore pointing slightly upward. In that way, the projectile starts out moving slightly upward relative to the line of sight. The pellet rises (because it is fired slightly upward) to meet the line of sight. The distance at which the projectile meets the line of sight is the distance at which the rifle is “sighted in.” In most cases, the trajectory crosses the line of sight as the pellet rises and then crosses it again as the pellet continues on its downward path. The height of the bullet path above the line of sight at the midpoint of the sight in distance is referred to as the midrange trajectory. Thus, the rifle is actually sighted in at two distances, the longer of which is generally considered to be the distance for which the rifle is sighted in. This situation is illustrated in Figure 2 which shows typical trajectories for identical pellets fired at 600 ft/sec and 800 ft/sec."

 

Now, you have to agree that the evidence does point to the fact that due to inclination when the pellet leaves the barrel it is flying upwards! This creates the primary zero point, and when it starts to fall and crosses line of sight it creates a secondary zero point. So it is not falling, it is rising, rising as in going up. Now this is not Mole you are arguing against but a make of air pistols, air rifles and pellets too! They do know what they are on about.

 

For air rifle sight set up you have a primary and secondary zero, when the pellet leaves the muzzle of the barrel it is on an upward trajectory. Quod Erat Demonstrandum!

Cheers Bigmac97, ordered some the other day. Just snowed under with work so got no shooting in. Got a tim of AA fields as recommended here.

 

Think i maybe started something about zeroing???

Tim knows his stuff

 

and so dose mole

 

this will go on for months lol

 

but tim will win
