I'm not 100% sure, and don't quote me on this by any means, but I don't think there are a lot of large cutting 85 grain mechanicals out there. If I were you I would bump up to a 100 grain head and at that point your options are endless...... Rage 2 Blade, Rocket Hammerhead, Grim Reaper, Grim Reaper Xtra Cut, WASP Jak Hammers, Rocket Sidewinder, NAP Spitfire, NAP Gobbler Getter............. the list literally goes on and on. You'll get the massive hole you are looking for and only lose about 3 fps in the process.
