I had almost a hundred .308 Winchester cases prepped and I have seen unprecedented demand for 30-30. I wanted to clear the decks of all of the distractions before I loaded the 30-30. I got the .308 primed and then went to verify the powder measure with my Lee Beam Balance.
|Do you notice something missing?|
|Here is the fracture. Sharp, inside (reentrant) corners are a crime against good design.|
Added later: I pulled some measurements off the balance beam and if my measuring and my math is right then a 7/16 carbon steel ball bearing will be within 2% and low (on the safe side), a 302 stainless steel ball will be within 1% and also low. That reminds me that I will not only have to measure the ball bearing's diameter but check to see if it is magnetic.
I wish somebody at the Lee Precision Company would authorize that a good moldmaker "breath" on this parting line with a small stone to radius or chamfer the corner where the crack started.
