I shot Grim Reapers out of my vertical setup...they were the only expandable I ever got pass-thru's with....they have a 'crossbow specific' model out now...which supposedly has been tested at speeds of 400 fps....
I've used them for 2yrs, and have had good success. Shooting a Horton Explorer w/ Easton crossbow hunter arrows and 100gr GR. Took a doe last year @ 38yds with 20" shoulder penetration. They shoot like field points, deploy on contact and easy to maintain.
I shot one of mine the other day to see if it flew like my Muzzy heads. It hit in the same hole both times.
Here's the good thing, ran it over a diamond broadhead stone, now it's sharper than it was out of the pack.
