Some Miscellaneous Chronograph Data
Grouse's post on "I don't remember doing this???" inspired me to look through my Photobucket albums for some old chronograph data that I was sure was there somewhere.
These are the ones I found that may or may not be of interest to someone out there.

Very interesting numbers there. Especially the .58 caliber with 105 grains of powder. The Pyrodex P was the big surprise. That would be a hard hitting load there. In the flintlocks of course I can only shoot Black Powder.

One thing I found interesting - look at the second and third lines of the first chart - was that with the same bullet and load I got significantly higher velocities with MMP sabots over Harvester sabots. But the group size with the MMPs was six times larger than with the Harvesters.
