FMJ arrow configuration to augment FOC

[msalm]

I just built a dozen RIP TKO’s 250 spine 30” draw w/ small 4 fletch, reflective wrap, and 100gr added up front. With 100gr bh (IW’s) they’re 515gr and shooting 286fps with a V3 @ 70#’s. FOC ended up a few tenths under 15%. I’m excited to shoot some animals this fall with them for sure.

I went down the FOC rabbit hole last year. Built decent arrow with FMJ but ended up settling on Axis to get FOC around 16% without having total arrow weight over 525g. The FMJ I worked up shot well but if you are really wanting to get that FOC up I would just switch to different arrow. And honestly, from what I remember, I think 340 spine would be slightly underspined with your setup. Probably need 300
