Got 50 new 303 Hor cases. Loaded them with CCI 200 primers, BECAUSE, Win and Rem were to large. I shot all 50 with various loads up to 18 gr. of 2400 with 150-165-180 gr bullets. I was thinking that after one loading, there might be a chance of seating Win and Rem LR primers. No dice! Guess this is a good reason to have a few different brands of primers on hand.
