O as far as blades I always take 3 of them and put two together with blades and one together with the practice blades. Those are always my practice ones. The rest I save for hunting to save on blades. If your one of those guys that must hunt with the bhs you practice with then just swap the blades and touch up the tip when you decide to hunt. You can always buy just the blades to so those 3 packs of bhs should last you a long time. Another reason I love muzzys! WCL
