Hi lads,

Just a quick tip for shooting up a steep incline from a hide plus the laymans terms and explanation for gravity and trajectory.

It may help someone who is intending on doing some brancher shooting.

Nice tip and good explanation. Do you always zero your scope to the same distance, or does this deepend on the venue and what distances your shots will be in? What is a good default zero distance for air rifle hunting? Do you have any good tips for zeroing the scope?

nice video si thank you, i remember from school - pythagoras theorem - indulge me for just a minute mate.

the tree's / buildings height is a straight vertical line 15 yards / 45 foot high tree / building
the distance from you is a straight horizontal line 25 yards / 75 feet
the angle up to the target approx 26 degrees is a straight line 29 yards / 87 feet ( had to guess the angle no protractor )
a triangle
therefore the shooter is actually shooting at a longer distance than the set zero, because the journey of the pellet would travel further than the horizontal distance
now, increase the angle of the target and the pellet travel increases further still, at 45 degrees the pellet travels about 35 yards / 105 feet. (assuming the same distance from the target) ( higher target this time, because of change in shooting angle )
is the effect of gravity reduced because the angle is more than 45 degrees. the pellet arc is somehow enhanced.
so to hit the target we have to shoot lower, when we should be shooting higher ( because it's further ) now i'm really confused.
think i'll go ratting with the dog down the canal for an hour

Hi Air,

Yes for a .22 sub 12Fp rifle i always use 25 metres as it keeps the pellet within a 2.5cm parabolic trajectory from 9 to 28 metres.

si ive been zeroing in the past at like 40 meters now from watching your videos i zero at 25 meters and use heldover. big improvement keep up the good work

@assheads Thank you much. I have since learned how to use a scope more properly. Thanks again.

So what if a pigeon is up a tree at less than a 45d angle? Say its 30 yards, do you aim straight on for 30 yards? and is the trajectory different at shorter or longer ranges on a less than 45d angle?

Is there a formula to calculate the parabolic trajectory of different powered rifles. How do you figure it out for a 12fp rifle and a 20 fp rifle? Thanks friend.

Hey si. Brilliant vids mate. Perhaps you could help. Have been zeroing and calibrating gun all day. Come dark have put on night site viper and am now half mill dot under zero ? Took leaf from your book when zeroing and used much smaller target dots than usual and have achieved much tighter grouped but cant understand the change when putting on night site.?

The twig probably wouldn't get to that higher speed after the 2 second period due to terminal velocity, the speed that you stated is right but the top speed would alter for the object that is falling.

@Zinaroon So to the u.s. that would be around $50??? Don't ya know we're broke over here & drowning in debt? Thanks.

I reckon I just don't understand longer distance shooting. Just today I had a rifle sighted in @ around 18 yds. I moved it back to 25 yds and the shots were high. I was expecting them to be low. I held it one mildot under and it was right in the middle bullseye. What in the world am I not understanding? Thanks for anyone's help.
