Hi Guys and gals,
I was hoping someone with experience in TAP or similar could help me out. I'm trying to tweak my setup. I'm shooting a G-force at 29" draw with 28" arrows (Carbon Express 3-D select 300). I haven't had it on a scale, but I have 70 lb limbs and they are backed out to around 62 lb or so. (about 3 turns). My arrows were 29.5" and I was shooting them with 125 and 100 grain heads. I was getting a bit of a right tail whip that I could correct by pushing my rest ~3/4" left of centershot. But, I wasn't getting any decent grouping at 10 yd (3 arrows, 3" diameter group). More troubling in my mind, was that the arrows were entering the target at different angles. To stiffen the arrows up I cut them down 1.5" and dropped my point weight to 100 grains. That helped a little. Next I dropped my point weight down to 75 grains and now they are all grouping great (touching arrows at 10 yd).
Are my arrows underspined? On all of the charts I am borderline between 200's and 300's. The 300's are stiffer so I thought they would be fine. But playing with point weight a little makes me think I am underspined.
Am I right?
Thanks,
Rick
