How can you determine how much weight you can add to your insert before you start messing with your arrow spine? I was wanting to increase my FOC a little and was wanting to add 50grn inserts. Right now my Im at 11.4% FOC and with the 50grn inserts it would bump me up to 14.4%, just dont want to weaken my spine to much. Any help would be appreciated.

try adding 25 up front and taking a few grains off the rear of the arrow and see what that does for you. on most arrows a 25 grain increase in tip weight will bump FOC 1-2%. 50 will probably soften you up too much unless you were way over-spined to begin with. you can also look at shortening up your arrows if you have wiggle room there.
what's your bow, draw weight, draw length and arrow length? -
Mathews DXT, 70lbs, 28in. Draw and 28in. Arrow. The only reason I don't want to switch to 125grn tips is that I have a ton of 100grn a Slick Tricks. Also, I'm shooting Axis 340s.Comment
