Deerbarber, congrates on a nice shot on that doe,
I would consider to crank that bow up to max and or find a conventional head that flies right for you . I think getting a complete pass through on a 250 lb big boy may be a problem with a expandable at 58 lb draw weight.
I just took a pretty nice buck up here a couple week ago . I use the wasp jack hammer sst's 100, similar to the snyper and I have 72 lbs of kinetic energy . The arrow passed through but not enough to stick it in the ground.
I would double check your Kinetic energy level , Gold tip.com has a chart to find this and be sure you are in the 60's
I have had a pass throughs with the Jack Hammers every time except one, when I glanced off a twig and struck the gut and opposit hip bone . Still recovered the buck , however . These expandables produce excellent blood . and extremely quick expiration , in many cases with in sight .
I say if you have the power to use them effectively they are definately the way to go.

P.S. I'll be down there in a few weeks to run one through one of those biggun's myself.
