-Please Help---I need to zero in my scope-

I have a break-barrel air rifle (.177 Gamo hornet) that is held by a clamp on bipod.I just got a new scope (Hammers 3-9x32ao scope) and I need to zero it in.
I tried multiple times and it doesn't seem to work, so I have a few questions.
1) If the bullet is high do I move the knob up to put the crosshairs on the bullet, or do I go down because the bullet is too high?.
2) I have an adjustable scope so do I need to put it on a certain setting?
3) do I start zeroing in at 10 yards?
4) will using a bipod effect the way I zero it in?
5) what do I do if the knob wont turn any more and I still need to move in a direction?
6) HELP
 
Deputy Dawg (I assume!),
First of all - deal with one thing at a time.

It's rather late into the night here in Europe so I'll keep this short & sweet.

1) You bring the scopes' crosshairs onto the Point of Impact of the pellet (it can seem otherwise, I do know)
2) For your stated scope approx. 4 or 5 mag would be suitable
3) 20 yards would be better - you are 'aiming' thro' an arc of the pellets trajectory, its a straight line of 'vision' through that & it cuts thro' twice, the first at approx 15-25 feet, the second, which you want at probably 30-35 yards
4) Yes, dont use the bipod to zero, its debatable whether you should use one at all on a springer (that's another story)
5) Would mean that you have run out of reticle adjustment, BACK TO SQUARE 1
6) Some help there I hope, if somewhat curt :)
 
If the bullet it too high (POI) Then move the crosshairs up to the POI- point of impact. Starting at a closer range will make it easier. 10 to 20 yds. A bipod with a sandbag or clamp in the rear is good. At that range any magnification will do.if your turret won't turn anymore don't force it. This means you might need adjustable scope mounts. The rear mount needs to be higher than the front mount( not much). You should also "center" your scope.there's a good post on here about that . Use the search window.
