QB Dave,
I must admit I had never heard of running the brass into the seating die. But nothing else was working so I tried it. Took out the seating die plug and ran the brass into the seating die. This started sizing the neck but still would not chamber. Took them back through the sizing die, gently, and I formed about 50 good cases. Fired formed a couple with 4 grains of Bulseye (needed to go to 4 in order to get the wrinkles out) with a wad of tissue pushed down onto the powder, worked great.
Thanks to the others as well for your help. Looks after about a year of that rifle sitting int the vault, it will now see some action.
