I think you may be off buddy. I tried to do a setup with the FMJs for myself but the best I could get was like 19-20% FOC and that was with 320 grains up front. 220grn Muzzy Phantom and 100grn bass insert
I'm sure Germ's FOC is lower than 27% I have 27.5" FMJ 400's with 100 grain brass inserts and 125 grain Slick Tricks with feathers on the back end and mine came out just over 21%
I figured mine the Old fashioned way! By measuring

Dan, what draw weight and draw length are you shooting? I was looking to do a similar set up, but found that with a 27.5" draw at 67 lbs. and FMJ 400s with 100 grain brass inserts and 100 grain head I'd be well underspined. I shoot 27" arrows and found that I would be underspined even if I cut them down to 26" at 400.
I scrapped the idea because the 340s put my arrow weight higher than I want it with the brass inserts.
60# 28" draw Those FMJ 400's with 21% + FOC are the best flying/grouping arrows I've ever shot. Total weight is approx. 500 grains.
