I ordered the girlfriend some arrows for her bow the other day and I thought I ordered the correct spine/weight for her but according to OnTarget2 I am way off? Heres the info if anyone cares to elaborate..... Bow: Martin mercury Draw Weight: 38lb---------Peaks out at 50lb with a raitng of 235fps DL: 25" A2A: 30" Single Cam I have a string loop, G5 Peep, and cat Whiskers on the string. Arrows Ordered: Victory V6 VForce Arrows .600 Spine 6.6GPI 25 5/8" Insert Weight= 14grns Nock Weight= 10grns Wraps= 8Grns Blazer Vanes= 3x 6grns= 18grns Field Tip Weight= 100grn Total= 318Grns In my eyes everything looks like it should be fine, but I wanted to be sure? She will mainly be shooting these arrows just for fun, maybe some 3d's, and if she wants to and is able to maybe hunt with next hunting season?? Thanks for your time!
