I inherited a 50-cal ammo can full of a mix of loose ball and A-P ‘06. Dirty with some corrosion that comes off with a green pad and brass cleaner (not Brasso). I pulled one of each and both look like the photo. Small number of darker powder nuggets. No smell or dust. Any thoughts? Headstamp on the A-P is SL 42: on the ball it is TW 54. Thanks (failing the photo upload, failing the taking a new photo, will edit if I figure it out) (figured it out I hope)
