Why put 300 grains infront of a .400 spine alum arrow?? especially if you know it wont work right in the first place???
momentum of a heavy arrow - and front loading carbons seem to work very well, where aluminums go all freaked out with the additional weight carbons do not. I don't know why - they just have a quality that allows a big range unlike the aluminum's I've shot
My experience in killing/wounding animals says to hunt with heavy arrows that shoot well. Thats what front loaded carbons are
