Hey guys I bought a cooper 270wby rifle and it will be arriving in the next week. I have dies and brass and a few bullets. I'm looking for load data for a good load for deer and elk that will perform well at close as well as extended ranges. I have used the new Sierra Gamechanger bullets in a different rifle and would love to give them a try but am not set on them. Any advice/info/opinions will be greatly appreciated. TIA
