Rookie needs help...bullet wont stay in neck
I am not a total rookie, I have been loading 300wsm and 270 for about a year. I just started 7mm Remington Magnum.
I am using once fired brass, redding type s competition dies. The die is a full length sizing die. When seating the bullet, I can push it by hand further into the case. I followed the hornady book and it notes the outside neck diameter of .315 and mine after sizing are .315 to .316. I have tried adjusting the die but it makes no change in neck. I also have some winchester fresh brass and it measures .308 to .310 on the outside neck.
I am sure it a simple answer so be gentle!
