Oh yeah, and the distance in drop between 0 and 30yds for the same setups...
398gr. 23in at 30yds. 71in at 50yds
428gr. 26in at 30yds. 75in at 50yds
500gr. 31in at 30yds. 90in at 50yds
That may seem like quite a bit but think about it... Between the lightest arrow and the heaviest arrow there is only 8in of difference in drop at 30yds. When your looking at a target at 30yds, 8in aint a whole lot
Now to the site pins... I dont have a way or the time to calculate your pin gap, but all you have to have is a program like AA or TAP or OT2 (archery calculators) to figure it out by measuring your peep to arrow distance at full draw, and your peep to pin distance, along with your arrow weight/length/fletch etc. etc... IF you were to calc. those, im sure you would find that the difference in pin gap is very minimal compared to what most people think...
either way, a well placed shot is what it is. You dont have to be a genius to do that one[8D] Most setups nowadays are SOOOO overly capable that it doesnt even matter, SO.... shoot what you feel comfortable with.
