[QUOTE="jde650, post: 865520, member: 16569"] Case length 2.225, chamber length 2.270. Is 0.045 to much? I have poor accuracy and lots of copper fouling. Case grows 10 thou to 15 thou after every firing, and one heck of a carbon ring. Usually have case separation after 4 to 5 firings. this is a new MGM 7 twist barrel. I wanted to shoot 90 gr vld bullet. I think this 0.045 is causing my problem but I have been wrong many times. I need some expert advice. Thanks jde650 [/QUOTE]
