Sounds like you have a fun pistol. If it will close on a Hornet case it likely had the rim recess deepened if it started as a 5.6x35R, the proof marks should tell you. A 22 Hornet should be marked with bore diameter in mm with 36 for case length. A 5.6x35R Vierling would be marked 35 for the case length. If it has the bore diameter marked in gauge measurement, it would be the Vierling cartridge since mm marking started before the Hornet was born. Shooting cast bullets is a good choice and 6 grains 2400 seems like it would be a good economical load. The gun and load are the type, my friends and I have a lot of fun with shooting at turtles. Notice I said shooting "at" not shooting, the little buggers have tiny heads. There is a high hill behind the pond to catch the bullets. It is fun, but also it is a pretty good exercise in range estimation.
