At the range today, I listened to all of the posts received and had awesome results. CCI mini mags performed well, no problems. Test fired one at a time then inspect, very little fouling and no change in the appearance of the barrel. Swabbed clean and put a few downrange with great results. This gun is so much fun to shoot, zeroed in my holo sight quickly and enjoyed some freestyle plinking. Cannot wait to shoot it again. Thanks to all for the advice and comments.
