Interesting! Good penetration! I'm presently in the processs of building a .73 caliber Jaeger, and after running some recoil programs, I'm starting to think maybe I went a little overboard on the caliber! So I will definitely be starting out with some "mild" charges in the thing! The ball will weigh in the vicinity of 550 grains......

I wonder what kind of velocity you are getting with that load?
