I sighted in at 20 yards as instructions stated with Diablo bolts and 150gr field points, moved out through the various distances to 60 and 70 yards. At 60 yards I noticed the group opening up to 3" and at 70 yards a much larger group.. 6 to 7" approx.
At 50 yards and below, 1 to 2 inch groups easily obtainable.
My question is, what is the reason for the sudden opening up of groups ?
I dont think there is any issue with bow or scope or mounts, all is tight.
Is it at greater distances, a greater FOC is required to stabilize the bolts ?
I have tried some dear I say it.. Horton Carbon Strike MX 20" with 120mm long vanes and these are worse, even at short distances.
I'm after a bolt and broadhead combo for use on small game at the longer distances. The Black Eagle Executioners seem to have a good following.... looks like PayPal might get another hiding
