What do y'all find to be the consistently most accurate commercially available target ammo? Using a 20" one in eight twist barrel. Shooting out to 400 yards.

Thanks for the replies.

Black Hills or Federal Match with a 75gr bullet for 400yds.

That and maybe getting into reloading and working up your own loads. It'd be cheaper and I haven't found too many "factory" loads (with-out paying out the nose for),that will out shoot reloads you can fine tune to your weapon.

Reloading is definately the way to go for match ammo.
