buying processed 5.56 brass?

Is there any way to tell if the once fired processed 5.56 brass is really once fired ? I bought 250 5.56 cases that he said are once fired and processed with the crimp removed, trimmed and ready to load. I loaded 25 of them with a 55 gr bullet and 24.0 gr of H335 powder which is not a hot load and out of the 25, the neck split on 11 of them the first time I fired them. If they were once fired why would so many necks split ? Is the only way to tell once fired is if they still have the crimped in primer ?

If they were fired in a machine gun chamber the processed without annealing, yeah, they could split on the first firing.

I never order sized ammo, I will pay to have the crimp removed though.

I get split necks on range brass from the local law enforcement range. I suspect that it was once fired, after it was processed and remanufactured from previous use, or something like that. In any event it was free.

Best thing you can do use use a reputable dealer with good customer following.
