cant hit birds out of trees?

i have a .22 Benjamin discovery i have the gun sighted in at around 25yards. bought a 3-9scope for it. i hit dead center every time i shoot at targets but when it comes to trying to hit a bird or squirrel i cant figure out where the pellet goes? does anyone have any advise on how to know where to aim higher/lower. i miss every shot. any tips?
 
well first thing is distance if your shooting passed 25y that's might be your biggest problem your just not adjusting for drop also if your shooting up into the tree this will also mess with you POA a little for aiming lower or higher again it comes to distance you can download stuff to your phone to help with that but without knowing what you fps is our goanna be shooting in the dark with some of the apps if you can provide more info one how far your shooting elevation fps then you'll get a bit more in depth help

 
i did watch the video! not gonna lie im new to airguns i had a gamo big cat 1250 for 2 months and i wanted to get a pcp so i got the benjamin discovery with the pump combo. i keep hearing people say aim low. and i always try to eye out how far away the target is. i been doing landscaping my whole life so guessing how far away something is. isnt that big of a problem. also what do you mean by "POA?" the fps on the gun from airgundepot it says around 900. im new to the airgun world and like to get into it. so any tips tricks will be helpful. also do i have to do an arty hold with a pcp? or is that just for springers?
 
Shoot at some targets at different ranges that allow you to see where the pellet impacts. That will give you an idea of what ranges you need to aim high for and how much. 

For angled shots pick a spot on the trunk of a tree to shoot for and see where the pellet lands. 

There's no need to make it complicated with software and chronographs. 
 
The advice already dished out is pretty good, but I found the video that Ted did on this subject exceptionally useful - even after 20 years of airgunning experience. Watch it, and watch again!

Also, practice - I don't want to be the boring one, but it's probably not a good idea to be shooting at live targets until you're absolutely confident in your abilities and your equipment. Shooting upwards isn't something that's always that easy to practice safely, but I tend to shoot at acorns, or pine cones or the like for this kind of thing.
 
I've been getting into ballistic calculators lately. Once you plug in the right information it takes a lot of guess work out. I didn't get the wind meter but I did get the pro version of the app. I've found that you learn where to aim after awhile so you don't have to refer to the app on every shot. I don't hunt per se, but I do shoot targets (items) past 150 yards.

 
Hi TVNoober,

Here's a critical piece of information that escapes many new shooters.....

When shooting at incline/decline - you calculate the horizontal shot distance between you and your target - that's the critical distance you are aiming.

Example: You are on level ground and are 10 yards horizontally from a tall vertical pole. There is a squirrel 20 yards up the pole. Calculate the shot as if the squirrel is 10 yards away - NOT 20+ yards. If you use the line of sight distance on incline or decline - you'll consistently overshoot the target. Why? Because the only portion of the distance that affects pellet drop is the horizontal distance. I make it simple and use a RX-1200i TBR Digital Laser Rangefinder which easily calculates the horizontal component (using the trig function). Also, I want to plug the ChairgunPro app (free) as this is an invaluable software program easily customizable for anyone's setup.

Now, if anyone wants to slide a beer my way - I could go on forever with this topic. Keeping this easy and simple - it works and I rarely miss. Love physics!!

FYI - Scope is Hawke Sidewinder 6.5 x 20 Tactical.

Good luck!! You'll get it!!
 
X-Hairs nailed it right on the head. Gravity affects every object vertically to the ground. No matter the velocity or the angle of the pellet. Even though a target is 50 yards line of sight but it's at 40 degree angle, you have aim at the target as if we're 35 yards because the target is 35 yards from it were to land on the ground
 
"tvnoober"im writing all this down lol. so what your saying is like. (i got my gun zeroed at around 25 yards) i see a squirrel in a tree around 25 yards up from me . the tree is 10 yards from where i stand. i should aim if as im shooting a target 10 yards from me on the ground? sorry if im a little slow.
Basically, yes. Did you get the point of Ted's video about the two zero points because of the parabolic trajectory of the pellet? What you see in the scope is like a laser beam, from what the crosshairs are on to your eye is a single plane, straight line. The pellet however travels in a subtly curved arch up through that plane and back down through it again on the way down. If your scope is zeroed at 25 yards and your shooting at something 10 yards away horizontally, even if it's 25 yards up in a tree you're zero point will have you aiming way high because horizontal and vertical motion are independent of each other. Trigonometry and physics are your friends here.

Technically speaking - the scope longitudinal axis can intersect ("kiss") the top of the trajectory (parabolic) arc providing for only ONE zero point. Now this has limits depending on the distances you wish to shoot - however the statement that two zero points exists is technically not accurate in all cases. Peace.
