So I am kind of stumped on this one, hopefully some of you more experienced archers can help me out.
I have my 100 grain field points dialed in all the way to 90 yards, if I set my pin to 90 I can hit dead on. I set it for 40 it hits dead on at 40. The problem is when I switch over to broad heads. Today I swapped over and at 25 yards I hit 3" high, thinking it was me I let another broad head fly and again 3" high. I swapped right back to field point and I was bang on. Why would this be?
Some specs, I'm shooting a 2009 Elite GT500 at 60 lb draw, 28" Gold Tip Expedition Hunter 3555 arrows. I haven't weighed them but I believe I calculated them to come in right around 360 grains. I am using 100 grain G5 Montecs on arrows that I fletched so the fletchings would line up exactly with the blades.
It seems like the broad heads would be lighter and that's why they would be flying high but I use the same arrow and go from 100 grain field points right to the montecs. I'm really stumped and am thinking of switching broad heads to see if that helps but before I drop some cash I thought I would check with the expert panel here.
One other thing to note is the left to right is the same from field point to broad head, no problem there.
