FG

Using some of your numbers and some of Dave's this is what my program shows...

I used open sights, your given altitude, about 40f for temp, and Dave's 1500fps @ the muzzle.... Ignore that it says for a Hawkin 50 - I just called up one of my guns and plugged in your infrmation for a 45 caliber...

1.61"s high @ 100....
