I was reloading today and noticed I accidentally loaded 2 cases of Federal NT brass. I had read about the Federal NT brass having crimped primer pockets so i had separated them and decided not to load them. 2 must have snuck by and I loaded them without problem. This is once fired (I fired) brass. I went out and shot them- no problems. So I decided to load the rest of them- 150 in all. Only three of them gave me a problem with primers, but they went in the second time around. Is there something else I should look out for when I shoot them? Wanna kill these ads? We can help!
