Dijon, all else being said, and agreement on the s385, your next question, and it was a good one, is to which primer, and I believe you referred to the CCI match primer. Well, if you are meaning the CCI BR2, I'm afraid, and partly due to being un familiar with the ignition issues of those powders, but I would opt for the magnum primer. My own personal preference is Federal 215, or 215 GM,( Gold Medal Match). Now a note on match primers,versus " standard"' is that they are not any hotter, but they are more consistent. Another primer that is not a mag primer, but a standard is the Winchester WLR primer. It is a standard primer , but is THEE hottest standard primer available commercially. The reason it is as hot as it is, is that most of winchesters factory ammo is " ball " powder, and is a little harder to lite. That all being said, I have used this primer in cases that burn around 75-80 grains of powder with great success. It even lowered my Standard Deviation, and Extreme spread from shot to shot, and overall average. Good primer selection is " make or break " situation, and that is why I recommend trying a few different ones. Take care, and think each move through, and don't overlook any pressure signs. That is why going with the slower powders is your best bet as well. Good luck!!!
