I shoot a mattews bow at 70 lbs. with a 28 in. draw. I currently use Rocket Sidewinder mechanicals. I am going elk hunting in Sept. and was hoping that someone might have used the Rockets on elk and could tell me how they performed. I would also like to hear if anyone has had good luck with mechanicals on elk. On deer size game I have had great luck with the Rockets, although I usually never get a complete pass through. The broadhead makes it out the other side but only once did the arrow make it through. Hope someone can help me decide on what to shoot this year!
