This may not be the correct way of asking, since I started a posting the other day about 9mm at Bi-Mart on Farmington....but here it goes. So on Friday I was at Bi-Mart on Farmington and asked if they had any 9mm. The lady behind the counter said they had a selection. Since I only wanted this purchase to use at my upcoming DH1 class I went with the cheapest. Remington UMC 9mm 115gr FMJ. When I opened the boxes at home to put into a tupperware container (instructions from the DH1 class), I found a number of brass casings with corrosion and scratches....looked like someone took 220 grit sandpaper to them. Now I saw her open the larger cardboard box that had these boxes of 50. Is this something new...that I've never heard about or is this fairly standard with Remington ammo???? I plan on using it Oct 17th at the upcoming class....do I need to be concerned or shoot away????
