Re: arrow weight
The gold standard had been around 410-420 grains. Some shoot less than that if there bows are able to and some chose to shoot heavier.
I tend to favor a heavy arrow. The lightest I have shot is 410 grains. I am shooting 545 grains now which many consider too heavy but I am not one of them. I lose a little in trajectory but I gain penetration if I need it, it will quiet the bow down and it is easier on the bow itself.
Just my preference.
I support all hunters, regardless of weapon or technique!
