I've used the swede for 30 years. No matter how fast you make it go, it's still 6.5 in diameter and between 120 and 140 grn. These are natural limitations. My current 6.6x55 is a modern S&L and 140grn do 2800 fps no trouble. My observation is that after 350-400 yards it's quite a slow killer, especially with lung shots. I don't imagine an extra 100 fps is going to change that much.
I've had kills out to 550 yards, but I reckon that's about the limit. Maybe 600 yds.
I don't imagine that the AI will improve things too much. You really need to jump up to a 6.5 mag of some sort, but the advantages over even a 270 are not going to be great.
