A long time ago when I didn't shoot as much poundage, I bought 75 grain Wasp High Tech Hammer Broadheads. Is a 75 grain broadhead heavy enough to hunt with? I shoot 28 inch Gold Tip arrows and a Fred Bear Epic Extreme at 64 pounds. I was thinking a 90-100 grain broadhead would give me better penetration and a better chance for a pass through. I am thinking of buying heavier broadheads. I would like to know what y'all think? Any recommendations?
