I bought a few cases of some Winchester 40 caliber 180 gr bonded ammo in plain white and black boxes. It has been offered by an number of vendors. Listed as contract overrun.

Ammo shoots fine, but problem when I try to reload brass. Seems like primers must be crimped in as crush some primers seating and some not able to seat. I don't think Winchester normally crimps primers in 40 cal, could be wrong. Has anyone else encounter this situation when reloading brass and if so do you suspect the crimped in primers may have been a unique specification for a contract order?

I purchased from ammoman who is now out. But this link to SGammo shows the same ammo.

I haven't heard of 40S&W being crimped, but who knows with the industry today. Take a couple of clear, sharp pictures of the bottom of some of the ammo, fired and/or unfired. Most crimps can be readily seen.

It says GOVERNMENT contract.

It's the government (military) that usually required crimped primers.

Toss it in the recycle bin.

Plenty of good .40 brass around.

What exactly do they plan to accomplish by specifying crimped primers? Trying to inhibit reloading?
