[QUOTE="codyadams, post: 2147843, member: 87243"] It is not at all uncommon, often times you can see more than that. An extreme and more rare example, my buddy had a box of federal premium vital shok 165 grain spbt 30-06 ammo, and after a 200 yard zero, was hitting excessively low at 400 yards. I checked his velocity, and he was consistently at 2050 fps. Yes, 2050. Box stated 2800. Pulled three bullets, consistently 56.5 grains of an extruded grain powder, so a roughly appropriate charge of an appropriately selected burn rate powder, I assumed they just used the wrong powder, an excessively slow one. Checked on their site, no ammo recalls, so I called them. They said sorry and sent a free box of ammo. I have had a couple friends with the hornady precision hunter ammo get above and under on stated velocity, however one consistent thing was that their extreme spread was all pretty big, around 50-80 fps.
