well i think i figured things out. i was consistantly shooting low yesterday and today. today i slid down my loop a little wee bit and started drilling my spot consistantly. only flyers i have i have IDed as heads that i bent blades on and didnt notice tiny bends and sometimes they shoot almost true, others they are horrible..thats on 2 heads...i really never noticed. i really need a good broadhead target...im shooting a foam one i got from Dick's sporting goods...its 2" thick harder foam...does alright but its shot up...they fly through and sometimes hit a pallet behind my target...should moved the pallet before shooting like i did last year
