Do you guys neck turn fresh lapua brass for your precision rifles? I have my k&m tool and most of the time i only use it when i am necking down 7mm-08 to 260 or situations such as that. I have turned my lapua brass before and it does have some neck thickness variance prior to turning but i cant say i have ever seen a consistent accuracy increase related to this step. Given a chamber that isint cut tight requiring turning does anybody do this step to "top" quality brass?
