i bought a box of federal 3030a ammo at the range the other week..while at Walmart,i saw the same ammo, but a different color box and it was marked WM3030a..do they make the same ammo and just put it in a walmart box?..or is it the same ..both 150 grain spoftpoint..i'm new to shooting so,i have no idea.i wouldnt think they would make a cheaper load, just for a store
