I'm looking for some input on caliber selection for my first long range setup. I currently shoot a 308 win at distances of less than 500 yards. The rifle is way too light for me to get anything at extended ranges done with it, and it's a Ruger, so I'm really not expecting phenomenal accuracy out of it. I'm thinking that I want to use a Savage as a donor. I prefer short actions, but may be willing to work with a long action. I will be using this for fun and for deer hunting, and I'm planning to build something in the style of the Noreen ULR or the CheyTac Intervention. Sure, they're ugly. But I just like them. Anyway, I want a vertical grip, and will be making the stock. Planning for something around 12 or 15 lbs because I don't handle recoil well anymore, and I'm planning on it to enhance my stability. Have a Vari-X 4 tactical 4.5-14x to mount on it until I select something better. So, on to my actual question... I want to be able to shoot out to about 1000 yards or more for fun. I won't be shooting anything bigger than a whitetail with it, and that will likely be at no more than 800 yards. I was orignally thinking of going with a 243 or 308, but I'm not sure I trust the downrange energy on them. Any other 6mm suggestions that would be effective and not too problematic? It gets windy around here sometimes. I was also considering 300wm. I was considering 338 Lapua at one point, but I'm not sure I want to mess with it right now. Was also considering 270, but not sure that it will do what I want. Also, what are your barrel length and twist recommendations for the recommended calibers. I'm open to ideas for other calibers as well. But the caliber needs to be flexible and easy to find components for. Yes, I reload. Yes, this is my first post, and I've been reading as much as I can, but wants some help tayloring this weapon to me. And yes, this is a great site.
