Thread: calling all experts

i have been having a bit of a problem with my 270.

gun 270 marlin fitted with a dan can
brass once fired factory federal fired in this gun all trimmed to the same overall lenght
dies lyman full lenght sizing die

problem

i can chamber a fired case and the bolt is not sticky or hard to close. i then run it through the full lenght sizeing die and chamber the case and i have a hard to close bolt and sticky bolt lift. i also find that it is quight hard to run brass through the die espichally the last quater of the lenght of the case. i use lyman case lube on a lube pad. so what i want to know is what am i doing wrong to cause this problem.

thanks woompha
