I am getting a ruger NO1 rebarrelled for 7mm and have been researching the difference between 280AI and 7wsm. I seem to be getting alot of conflicting data from the different reloading manuals. (some seem to show these about equal) I have ordered a Broughton 1-9 twist barrel, planning on a 24in barrel predominately for elk hunting in eastern WA and a moose hunt in BC this fall. Would there be much of a gain to go with the 7wsm over the 280AI ? I don't have much experience with long range hunting and five to six hundred yards sounds long to me right now. (they tell me that the average shots for the moose in that area is usually under two hundred yards ) OH, and I was planning on the 160gr + bullet range. Any advice will be appreciated. Thanks guy's.
