Well, I haven't done any formal or detailed testing as to your question but.....
I have a Sport I and I frequently ping steel gongs at our range in the 400 yd distance with 55 gr FMJs (reloads). I've never put paper out at that distance. And I don't hit the steel EVERY shot....but most shots. (Sorry - I don't know how big the plates are at that distance....they're on the order of 12"x12". I would guess.) And those are FMJs. I have a match grade 53 gr bullet I load (Hornady) that gives me 1" groups at 100 yds. I don't know how those do at longer distances.
