I have decided to increase my arrow weight but do not want to change my broad head. Currently shooting a 340 Easton Axis arrow at 29" with a 100 grain Magnus 4 blade Buzzcut, 50lb Onza 3 at 291/2" draw. I have a dozen new arrows and want to add 10 grains to the front to help stabilize this combination, can I screw a 8/32 allen screw in to the insert behind my broadhead to achieve the desired weight of 425 grains for this setup. Vanes are Blazers.
