Do ya have any chrono data from the 38/3031 load?
Manual's velocities seem to vary greatly for 45-70.
I have not. A buddy of mine loaded same with 39 gr and shot them from his guide gun and got 1500. He said he thinks that his chrony is off though as that is way above what book says it should be.
I'd be that buddy...
I don't know that my chrono is "off", but I don't know that it's "on" either. It was dang close on some 22wmr loads, and fairly close to some 44mag loads according to the book. I could have shot through on a funky angle and I know with an arrow that will throw funky speeds, but three shots were 1409, 1493, and 1512. Phoneman and I figured that according to book calculations, that load should be in the 1300-1350fps range.
