I have a question concerning the Rocket Stricknine mechanical broadheads. My current setup shoots a 412 grain arrow at abot 262 fps. Would this be enough speed for a mechanical head with such a large cutting diameter of 2" ? These things shoot great out of my bow and I plan to initially try them out on groundhogs. I have very little experience shooting mechanicals and would appreciate some insight from you guys as to whether this combo would do a sufficient job on deer at the current velocity that I am producing or if I would probably be better suited to use a head with a smaller cutting diameter ?

Thanks for any replies .
