For all practical purposes, anything in the 7mm08 through '06 class can give good groups to 500 yards. Any of them are "don't bother to think; just point it and pull" for Bambi to 300 yards.
Seriously tight groups come from tweaking a rifle and tailoring a handload, plus mucho practice.
For hunting, as near as makes no nevermind, sight in for two inches high at 100; that's near dead-on at 200 and about six inches low at 300. Going out beyond 300 means really knowing the distance and judging the wind.
But it's claimed that 90% of all deer are killed inside of 200 yards. Based on what I've done and seen, well, yeah, I wouldn't argue with that.
