Get the 300 grain ones,then install them on an arrow. Then,carefully...and slowly,grind a bit off the rear of the points,while rotating the shaft in your hands. Grind the point in the rotational direction of the tightening sequence so it does not "unthread itself" during the grinding procedure. Go slow,weigh often until you achieve your desired weight. This trick works great for putting 5/16 heads on 9/32 arrows like the Axis. Taperring the rear of the point so it removes easy from targets. Works great buddy. rat'
