(b) It is unlawful to hunt big game animals with any arrow measuring less than 20 inches in length or weighing less than 6 grains per pound of draw weight with a minimum arrow weight of 300 grains.
I draw 70. 420 is my minimum. My arrows are over that. 27.5" FMJ with brass inserts and 100 grain broad heads put me at 515 with FOC of 14.5%. Seems that these fly nice, hit hard and bury deep in targets.
