[QUOTE="Outlaw6.0, post: 1055853, member: 23486"] I have a good bit of experience with both the .243 & the 6mmAI (as well as the 6x284). With my accuracy loads the 6mmAI pushed a 85grn Partition 300-400fps faster than I push an 87grn V-Max out of my .243. 24" bbl on the .243 & a 26" on the AI. I don't have a use for bullets lighter than that at this time. The AI is an outstanding cartridge however, as Mud somewhat alluded to, cases can be hard to find for the 6mm Rem. The 6x284 will outrun both with much easier to find cases however, I do not believe that case suits light bullets. It really starts to show it's prowess over the others when you get to the heavy for diameter projectiles. Case in point, I can push a 107smk out of my 28" 6x284 to the same speed as my accuracy load in the 6mmAI with an 85grn bullet (3500fps). If you're looking for more velocity, the AI is a great choice. Or, you can simply improve your 243 for a pretty acceptable gain as well. Bore life is a highly subjective subject & in my personal opinion, near useless. There are far too many parameters to discuss before reasonable bore life numbers can be reasoned. t t [/QUOTE]
