Congrats power on your hunt. We never really weigh our animals but around 400 (give er take a few pounds) would be close for a spiker. I shot a 5x5 this fall and we estimated him around 600, figure his 1/4' s were about 125 a piece...heavy to haul up the valley I know that

. We also got a spiker (head be around that 400) and the biggest a 6x6 that was easily 750-800...he was a lot of fun
