I have shot a 700 Rem .308 my adult life. It is all stock with a nice local gun shop scope. I am wanting to move up to a nice custom gun with a long range caliber. I sure like the AI in the .338 Lap, but I am not sure that would be the best choice. I have plenty of self taught shooting experience with a longest kill (deer) of 825 yards. I know that is not far for a lot of you, but that was a great shot for me. I really would like to spend the rest of my adult life learning the 1000+ shot constantly. What caliber would you all recommend and what brand or gun smith would you recommend. I am in the Houston area. Thanks for all your help!!!
