So i was getting extremely frustrated and decided to just screw around with 5 rounds and I ran them through an extra sizing die I have without the decapper in it and I had to laugh when they actually sized down to a size that the LWD barrel would load. They are unusable though as when you load them any longer than 1.125+/- they the bullet can almost be pulled out by hand.
Just thought it was funny as I am extremely upset with the dumb barrel. .401 lead rounds just seem to big. The FMJ's I have load fine and pass the plunk test with ease but move to lead and its a no go.
