Yes I was really suprized that the magnum primers resulted in lower velocity. I had forgotten that as it had been a long time since I looked at that data. I got the same thing this summer when chronographing some loads in a 56-50 Spencer CF in a Peabody carbine. The different primers were the Federal 210 and the CCI-250. The magnum primer gave a lower velocity.
At the time I did that work with the 45-70 (2002) I had never heard of 1 1/2 Swiss. I never tried that until 8 or 10 years later. It wouldn't be too difficult to try is as I have some on hand now. May have to try that next summer as it would be interesting to see how the 1 1/2 Swiss compares.
