They didn't get crushed when you resized them? You sir, have a delicate touch on your press. Well done working those cases.For inexpensive ammo, Blazer Brass is acceptable for what it is. I've reloaded some of their cases, no different from other brands.
I bought a 1,000 piece bag of CCI aluminum .38 Special cases from Rocky Mountain Reloaders some time back. These were unfired cases that had been pulled down. They were primed, but I felt it wise to resize them (without decapping) even though they hadn't been fired. Aluminum has a different "memory" than brass. Anyway, they didn't need cleaning, were already primed so I ran some through my Dillon 550, no problems. My grandson has fired a lot of these with low-velocity wadcutters. One use and they are scrap, they don't hold up to multiple loadings.
