Hopefully this is the correct place to put this. I got this over at arfcom. There is a petition to Winchester to resume production of 5.7x28 ammo ( I didn't know they were or even considering production of the 5.7 ). Anyway you can go to petitiononline.com/57ammo. You can sign the petition and also put some comments in. My son and I are numbers 346 & 347.I don't know if will accomplish anything but it would be nice if there were other sources for our ammo.
