I am setting up a set of X10's for my Recurve to shoot a FITA on the weekend.
In the past for Recurve I used to just shove the heaviest point into the shaft and shoot it, believing it gave the best performance...less drift.
The usual heavy skinny arrow...less drift
but the arrows weighed in at 384 gns.......and I had a play with AS and the drift calculations.
It was interesting to see the drift decrease as I took the point weight down to 90gns and then when I got to 70 grns the arrow started to drift more.
So the optimum point weight was about 85 grns......so I'm chopping them off at 90.
I wonder how many other Recurvers just throw the whole 110 - 120 point s into their shafts?? the difference in drift was small 290mm vs 313mm......but it was teh difference between a 5 and a six at 90m.
The compound bow is a much more efficient mechanism and shooting heavy X10's seems to decrease drift....as I have discovered. So without playing more the turnover on my compound may be up around the 400+grn mark.....before an X10 becomes TOO heavy.
Just some late night dribble :)
