Fire Forming in a Martini action
I just fire formed a box of .22 Hornets into the K-Hornet in a re-barrelled bsa martini for the 1st time ever.
I have noticed that the cases width expanded only on one side. It is quite prominent just forward of the cases head.
With my limited knowledge, I am guessing the case is not being centered when loaded and is laying on one side of the receiver. My next assumption is that the case has now been overstretched on the one side and is a prime suspect for early head separation.
Can anyone shed some light on this.
