Hey everybody. I'm new to colorado so I'm having a first time elk hunt this fall. I have a 338 barrel blank and I'm wondering what cartridge for a max of 300 yards on broadside targets. And let me say that I have let a lot of game walk because a broadside didn't present itself so I will wait for the right shot on this one too. I know I don't need ultra mag performance at this range I just want to do it right before I move home. Thanks to all those with experience and let's hear it!
