I got two boxes of Winchester white box .40 S&W 180 grain full metal jackets. I had a gift card and got it because I didn't have anything else I needed in the store, and I could reuse the brass. When I unboxed it and went to load it up, I noticed something.
The cases were roll crimped! The crimp was clearly distorting the bullet around the entire circumference. What gives? It's been a long time since I've bought factory ammo, and a really long time since it was any Winchester. I had some Remington laying around that I finally shot up a few weeks ago, but the cases were taper crimped. But roll crimping? It headspaces on the case mouth....
I know that I get good performance from what I make at home. But the Winchester just printed terribly, the only upside was that I collected all the brass. Does anybody know if this is how they always do their ammo? A friend had a box of Winchester 9mm, and it was taper crimped. I don't know why a big time manufacturer would be doing it wrong.
