I gave my S&W 1977 Model 27-2 some exercise with .38 Special loads. 12 shots in each group, 158 grain RNFP bullets over 4.0 grains of BE-86, 10 yards, elbows rested. The upper group used CCI primers, the lower group was Servicios Aventuras primers. I know 12 shots is not a statistically significant sample size, but the difference in groups is intriguing. In your experience, can primers make that much difference?
