I did see the post where you answered the OP about the Winchester ammo.
This post below is the one I quoted and has nothing to do with Winchester ammo but it's alluding to the fact that this person couldn't have had a failure with a Berger because he missed.
I stated that I did have a failure from a Berger that penciled through which after some research isn't that uncommon. There's remedies for this but I feel that I shouldn't have to do more than worry about making the shot.
I know you and many others have had good luck with them and as I said earlier confidence is what each of us are looking for.
