Has anyone bought and tried out the can am 223 in the spam cans yet? I have had the yellow box before and loved it. just wondering if anyone had problems with the stuff in the spam cans. I have a case on order. just hoping its not like these cases of 7.62 x 39 that's supposedly non corrosive and turned out to be corrosive. was told by the local surplus store to rub a couple shells on a nail and leave it sit for a few days and see if it rusts. they said it works. they sell a lot of ammo. But hopefully i will find someone that has used this already and had no problems. just don't want to run it through my ar build and it be corrosive
