Ok first off I want to say Hello. I am new to the site and I am trying to get into longer range shoots on elk. I have a Browning A-Bolt M-1000 Eclipse with the BOSS Muzzle break and Leupold VXII-4x12x40 w/ duplex recticle. I just got the rifle and have never hunted with it. I can consistantly shoot 1/2" to 1" groups at 100yds with federal premium 180gr. My question is what ammo is straight shooting at 5-800 yard kill shots. I also was curious what else I might need to make those shots. Im going to Colorado on Nov 3rd so I wanna be ready to go thanks in advance.
