How much of a grain differance would you say it would take to effect the grouping of arrows? What I'm trying to get at is with any given group of arrows shot how much weight differance between arrows would it take before a noticable differance is seen in groups? I understand that the farther out you shot the better chances of seeing poor groups. Lets use 40y as the max range.
Right now my 6 hunting arrows weigh 503-506g with broadheads on.
My 6 practice arrows with the same brand of broad heads on are 503-509g. Figure in that the heads had some dirt and target crud on them.
This is my set up..
Browning Marage Pro Hunter
65# pull, 60% let off, 31" draw
31" Carbon Express Turminator Hunter 6075 arrows w/ 100g Thunder Heads
Gold Key plunger rest
Allen Tru Glow sight
ZerOgap Caliper release
I've looked at upping the draw weight to 70# or or 75#. I can draw the already set 65# all day with no issues. What do ya'll think? Also what would you say my added speed would be?
