Re: sighting in range
it all depends on speed and what kind of sighting system you have. if you have a scope with 20 30 40 50 lines then you need to shot it at those distances and check the zero at each to know where it hits at each. if you have a scope with a speed ring it is a little different and can be tuned for your set up.
either way you need to practice at different ranges unless you plan on just hunting at 23 yards.
they are not rifles. my bow shoots around 328 fps and i drop around 30 inches from 20 to 50.
Now your diggin' where the 'tators are!
