Friend,I recently made up some Victory V Force .300 arrows for a Bear takedown with Rose Oak limbs,same weight,draw length and centershot as yours.They seem way stiffer than the Vapor Pro .300's that I had been using for that bow.I have 424 up front on the Vapor Pros,including,point,inset and footing.28.9 % FOC and 714 grs total.
The Victory arrows needed 458 grs up front.This turned out to not be a bad thing as they are now almost identical in weight to what I am used to shooting but 31% FOC.I have made some hard hits and side slaps with them on hard materials and they seem every bit as tough as Gold Tips and Vapor Pros.
