I picked up some lead 124 gr cn bullets. I am using SR 7625 at 4.0-4.2 gr powder charge. My pistol cycles perfectly but not consistent at all. Scattered all over the place. I started at 1.080 which had the worst group I've ever seen and finally ended up at 1.163. Decent grouping but still want better. I cannot lengthen the coal any further than 1.165 without falling into the groove of the lead bullet. Does anyone have any suggestions in how to get a tighter group? I normally load round nose bullets of lead or fmj or plated. I've never loaded a cn bullet and may not again if I can not get a good grouping. I generally load 10 and test, then re test, so far I've loaded and shot 150 of these rounds and at best 8" group at 25yds. With My LRN I am getting about 2" group at 25-30 yds. So if anyone has some insight I'd greatly appreciate y'all's help. Thank you.
