Using a .308 on Elk at 500 yards is, at best irresponsible not to mention reprehensible. A .308 180 grain Nosler partition might be a good 100 to 200 yard on an elk, beyond that it's a no go. Not enough energy to make Mr. or Mrs Elk take immediate notice that their bodies have been invaded. At 500 yards the best one could do is wound an Elk and cause it to run away and have a painful death a long way from where you were hunting. If you are going to go Elk hunting be able to shoot a reasonable elk hunting round. Yup we are talking a .270 (Jack O'Connor's favorite). 30-06, 300 Win Mag or 7MM Rem Mag. Other larger calibers may be used but be sure that recoil management is well within our capabilities and at ranges that are reasonable. Teri Anne.
