I’m loading my very first rounds ever with some components I could find locally while waiting for the stuff I ordered so for reference I loaded Hornady 140bthp (not eldm) match bullets over 40.5-43.1gns of H4350 cci 250s in Hornady 1x fired brass at .020” off my lands it was about 35 degrees Fahrenheit my concern is the way my primers look I believe I understand what cratering is correctly but I had some that looked like this at my lowest charge it dosent seem to be related to powder charge and it dosent look like cratering as I understand it more like pressure molding the cup to the firing pin hole than metal flowing outwards I have an arc nucleus CRF action so I can’t go by ejector markings and at no time did I have any detectable bolt lift change and speeds seemed acceptable though I don’t beilieve I would go above 42.5 range in warmer weather should I be concerned?? Were 250s not the right move seems that’s what everyone was using
