Swamp,if your using band saw blades,you can make a 150 gr. point like this; 3 1/2" total lenght,1 1/4" wide, the triangular blade being 2 1/2" long ,with a 1 " tang
with a circular saw blade,try 3" total, 2" blade,1"tang. I usually cut mine out a little larger,so if they're to heavy,just grind a little off to desired weight. God Bless
