Qoo Posted May 20, 2016 Author Share Posted May 20, 2016 I also have the CK Thunder in 9mm I am loading 124hp MG's with 7.2 of Silhouette @1.140 PF 172 Some where around 1.143 is where I stopped having plunk fails. I shoot with a guy that has a custom built open gun also with the KKM barrel and he is also loading short. The KKM barrel seems to have a very tight short chamber. I use my barrel to chamber check everything I load. Many rounds fail to chamber correctly and I pile them separately. I have rechecked these fails that have some minor brass bulge ect and 80% + pass the Dillon case gauge. Once you find your load you'll find the accuracy very good. My CK has been 100% since getting my load dialed in Very valuable information. Thanks much! Link to comment Share on other sites More sharing options...
