A friend and I are looking to buy some bulk .223 for our AR-15s. We are interested in the Winchester SS 109 green tip that is in Shotgun News for about $220 for 1000 rounds. Has anyone have any feedback on this stuff? Or can anyone recomend a good type of bulk ammo to buy (preferably hollow-point)? We are looking for plinking ammo, we aren't shooting at 1000 yards, but we still don't want to buy ammo where every other round is a dud... Thanks.
