I wouldn't even consider a semi-auto.
I don't think I would go that far. The best I have done with my 700P was a 5 shot group the size of a quarter. I did that at 100 yards. I thought that was pretty good until I saw a 5 shot group shot at 300 yards with an LR308 that was the same size and witnessed by Illinois State Police. I wish I could find the site so you could see the photo. Unreal.
