[QUOTE="Mc Fraser, post: 1641865, member: 106529"] Hello, I have a Lee Breech Lock Classic Cast and Lee dies for my 270 win and 300wm. On my 270 i use Nosler brass, 140gr Sierra SBT Gameking. Somehow I get 5-10 thou bullet runout and I cant seem to figure why. I measured the fired brass with a Sinclair concentricity gauge - very minimal runout, then i neck size it and measure again 1-2 thou run out, after seating the bullet 5-10 thou close to bullet tip. All this with Lee dies, then i went and bought series a redding dies and got the same result. The only item that i can think of that could induce runout is the press, and im planning to use a friend rcbs to check that theory. [B]Anything else that you might think of that might cause that much runout? [/B] On another note i think im disappointed with redding dies, i got the same results the only diff that i can see between lee and redding is the price. [/QUOTE]
