If you really want some 10 mm to save as collectable get Winchester Black Talon! You can find it on gunbroker.com it is packed 20 rds per box and is over fifty dollars a box! It was the ultimate ammo in the 1990s before being removed from shelves. I have some 9mm & .40 as a collectable maybe it will save my life one day. If you have money lying around I would get a couple boxes.
