RE: Broadhead grain
Grain refers to weight. A 125 grain broadhead is heavier than a 100 grain broadhead. The heavier the grain, the bigger the blades and head. Theorically, that means a bigger hole. But not always. If you read these posts you'll see guys using anywhere from 75 grain to 125 grain broadheads for deer. The tech. guys can better explain it than I can but I know the 125's don't fly as flat as the 100's do. They drop more. I guess it depends on what you have your bow set for poundage wise and what arrow you're using to determine which size broadhead to use. I asked my guy at the pro shop and he recommened the arrows and broadheads for me. I'm learning about this too so I'll be very interested in hearing what the panel says.
