i just got a 100 round box of wwb .38 special plinkin' ammo from walmart, and when i got home i noticed that some of the rounds are stamped "38 SPL" and some stamped "38 SPL +P". i haven't gotten a box of these in a long time, but i don't recall ever seeing those mixed before. anyone else seen this? are the ones stamped "+P" really, or did they just use the wrong brass in the batch? other than the stamp, they all look the same.
