Hello to all. I got a newbe ? so take it easy on me.
I am new to crossbows and have a hard time understanding shooting distance.
If you are on the ground 20 yds= 60 feet
but if you are up a tree 15 ft and a deer 60 feet out that would=105 feet=35yds.
I try this tonight from my porch 10 feet up block at 50 feet out I use my setting for 20 yds because it looked like that and I was realy on but if you do the math it would be 40 yards ? What am I missing? I dont have the money for a range finder right now (still in school) so any advice. Thanks
