I have been reading a lot about people going to heavier arrows to get more penetration and quiet their bows. I did a calculator and it seems like I have a negative FOC, is that possible. Here are my measurements Arrow length, 29.75" balance point, 14" from throat of nock I came up with -2.94, hoping I maybe did that wrong. I shoot 100 grain expandables, and have never had a problem, but I am always interested in improving. I shoot maxima blu RZ 350s, that 8.45 grains per inch. no inserts, standard 3 vane blazers. 30" 65# draw. Thoughts or suggestions?
If you aren't using inserts, how do you fasten the tip or broadhead to the shaft? That would also explain the negative foc. Without an insert a 100 grain broadhead doesn't have enough weight to tip the balance point toward the front of the shaft. Sent from my SM-J320V using Tapatalk
You have to take the balance point with the insert, 100gr head, fletching and nock in the arrow. Sent from my Pixel 2 XL using Tapatalk
