OK, I can figure this one out, but which is more (most) accurate at 200 meters?

Well, I may be somewhat biased, but I’d say a 30-30 with some good ole Sierra bullets.

I'd bet anyone seriously shooting/reloading either caliber gets the same MOA @ 200.... Which do you have and want to shoot.... You don't even have to load for 30-30, straight up Remington or Winchester 125-150gr ammo is cheap and plentiful and reasonably accurate.... IMHO.
