Thanks to all the replies but, I have never ever shot reloads. The Winchester AA'S stick and wont shuck reliably. That is, on the first two fired they shuck just fine. The second two fired, it's always the right shell that wont shuck. (Not the case with STS's).
I always swab my barrels between runs.
As far as finding STS's at WalMart, yes I am aware of that but I only shoot 7/8 or 1 ounce loads.
Again, I NEVER shoot reloads. These are all factory new shells.
Thanks.
