Re: ???????? advice would be helpfull
I had a set of Hornady Custom New Dimension dies in 6.5x284 that did the exact same thing. I sent them back and ordered a set of Reddings, problem solved.
I like H4831sc or Re-22 for the 140s, H4831sc is more temp. stable but the Re-22 is faster and more accurate in my rifle.
Ignorance can be treated with education, sadly there is no cure for stupidity.
