So I'm using 6.5 cr lapua brass that I shot once. And I have rcbs match dies with neck bushing. I am trying to achieve 2 thousands shoulder bump but I get 1 thousand sometimes and sometimes 4 thousands it's weird. And if I press the bras twice instead of once I get and extra bump. Any advice while be appreciated.
I'm using a Franklin arsenal press.
