RE: Full metal jacket arrows / broadhead line up
I dont think it really matters unless your shooting a drop away rest and need the clearance for the blades on your shelf. As I did last year. So when I make up my arrows I scew in a broadhead and line it up so when I fletch the arrow it is inline with the blades on my broadhead. Its the only way I know of to do it with carbon arrows without damaging them.
