Congradulations of your buck. Way to go!! As far as it being only a spike? Let me tell you, they taste a whole lot better then a big old swamp buck. And as much as I' ve tried cooking the horns different ways, they never were worth eating..
Nice job. Taking a deer with a smokepole is a lot different then a center fire. You get one chance, and then there is always that chance that the thing will not go off.
