I just picked up 3 packs of the 100gr 4 blade magnums. I am looking forward to myself and my stepson to try these out. Both hunting and see how they shoot. I am shooting a 436gr DCA Hunter 350 (50gr aluminum insert) out of a 29 inch draw 65lb Bear Motive. 296fps at my local shops chrono. My stepson got my hand me down Mission Ballistic. He's using GT Expedition hunters probably around 375 grs. 27.5 dl at 60lbs. When we get some results foam or meat I will check back in. I got a small buck last year with my 3 blade rage, did the job but I wasnt impressed with the penetration. I am going back to fixed heads so I can get a pass thru. I hear good things about these heads on forums and my buddy killed his first mountain lion in Idaho with the Slick tricks. Put a nice hole in that one and burried in a tree behind it.
