OK guys, I posted on here earlier in the week with some arrow questions. I finally got around to bare shafting. I shoot a 55lb Montana, and draw around 27-27.25 best I can tell marking my arrows when I draw. Right now I shoot 2016s cut to 29" with 125 gr heads. I was getting some nock left in flight in any wind. Any.. I decided to bare shaft these arrows.. Got bad results. They wanted to nose dive and looked to be planing hard with left to right. I also had some old 2018s around a few cut to 28", one cut to 29", one cut to 28.5. Have tried a variation of head weight and shaft length and the best combo I get is 28" 2018 with 175 gr head. The problem being, once I put a broadhead on I cant draw all the way because the back of my stinger hits my first finger on bow hand.... These arrow though with a good release the bare shafts flew like darts. I tried 28.5 with 145-155 and it flew ok, but slight nock kick right in flight if my release wasn't spot on. So far it seems like my Montana prefers a stiffer arrow than my number crunching came up with. Will 28.75" 2018 with 150 or 175 gr heads put my arrow flight similar to the 28" 2018 with 175? Thanks.
