I shot my first bull elk (5x5) in Colorado in 1996 with a 7mm RM shooting Federal Premium 160 Nosler Partitions, 175 yards away 3/4 facing away, shot behind the shoulder and exited the brisket the size of a pool ball. He ran about 40 yards with blood all over the place. I've seen a lot of animals killed with a 7mm RM, it just gets the job done!
