I have an elk hunt booked for December. For the last 40 years I’ve used either 180gr Nosler Partitions or 180 gr Failsafes. Obviously, Failsafes are no longer made and I can’t find any factory loads with partitions. So, today I purchased 2 boxes of federal premium 30-06 loaded with 180gr Trophy Copper bullets. I’ve done a little reading today and everything points to this being a fine bullet for elk. For the last few years I’ve used my 308 win loaded with federal premium factory ammo and 180gr partitions. No problem killing elk. Recently, My son gave back to me my old Ruger MK2 with which I’ve killed probably 25 elk. I’ll use it this year for the first time in many years. For those of you who have used the trophy copper bullet, we’re you satisfied? Thanks for your responses.
