45 ACP small primers ???

[spike1]

So here I am reloading my stock of 45's for the years. I keep having these primers that will not go in ??? So I just toss the case in the junk box and the damage primer. I looked in the junk box when I was through and noticed all the cases were marked "45 AUTO WIN NT" . I verified these cases take a small primer ???? Small primer in a 45 ???

Whats with this ??? Never had this problem before
