I shoot a 370 grain arrow at 286fps...total of about 67 lbs of KE.

I had issues with the Bigger fixed blades that I've used it he past...planing and wind shearing all over the dang place. I could shoot field tips and shave fletch at 40 yards....My Stingers corkscrewed down at 20. Snuffers were 7-8" in any direction but never in the same spot, Muzzys were a little better but not much.

4" offset feathers...I went with a compact head. Rocket Ultimate Steel in the 75 grain. 1" cut and shaving sharp....mean looking little things.

Everything I hit I blow waaaay through.....problem is lack of blood. Hole's to small for my liking. Everything's died within 30 yards or so but I've made good shots and heard or seen them fall. But blood even na double lung with a low exit was scanty at best.

I need a bigger cutting diameter.
Enter the Rocket Wolverine. 75 grains (didn't want to have to resight at all...middle of the season here) and 1 1/4" cutting diameter. Amazing how much a 1/4 " can make. Blood everywhere and spewing.

Only shot one with them so far but but they fly great and did what I was looking to the to do so....
