30 X arrow flight
I've got them cut to 27", 100 grain nibs, blazer X2 vanes, running a pin bushing and bohning pin nock out of the back, i shoot 3-d and these arrows shoot like garbage out of my XLR8, i shot at some distance the today and last week, and they dont group well at all, 3 out of the 5 i was shooting seemed to group decently, 2 grouped really well....the other 2 arrows were just not even close to to the other 3. I was shooting well, i could literally see the arrow kick right, and cork screw towards the target, leaving them kicked in the target and not impacting tightly to one another, The center shot was eyeballed, and i know sometimes the pin bushing can cause a big pain in the butt. Just wanted some input on what i should do, i'd like to find UNI busings to fit these, but no one seems to know what size i need.
Any help is appreciated.
