I have attached a picture of two brass recently fired from my 7mm Dakota. The one on the left with extremely flattened primer was a new piece of brass loaded the exact same as the brass on the right which had been fired for the third time and only neck sized. The only difference between the two loads was the new brass head space was 2.062 and the neck sized brass was 2.079. Should I have two back the charge off on forming new brass as the excess head space could cause excessive pressures???
