I recently purchased a box of INDEPENDENCE brand ammo in 9mm. When I opened the box I immediately noticed that the casings showed different stages of tarnish, some new-looking but many were very dark and blotchy. Another thing that caught my eye was that several appeared to be different lengths, 3 different lengths actually. I have never noticed this before with other brands of ammo but since this is my 1st box of Independence I thought I'd find out if this is normal with their ammo? The casings all appear normal so I am thinking that maybe some were seated farther in the casing. Is this ok or should I discard the oddballs. I don't think I'll be buying any more of their ammo if this is how good their quality control is.
