Of the 9 elk I have taken, 7 of them were with a 270 and 150 gr Nosler partition. The other 2 were taken with an 06 one with a Sierra boat tail cup and core, the other with a Hornady spire point. Off all of these the longest shot was 350 yards with most 150 yards or less. I have no experience with Bergers but have mixed reports from trusted friends if the shot is high velocity and short range. No personal experience so I'm sure the Noslers and Barnes would be great
