We did the conversion (or rather a more talented friend of ours did) from .22 Hornet to K Hornet in a Handi and my old Savage 219. They both turned out very well and shoot as accurately as ever. I've learned a little about shooting .22 cast bullets in the fire forming process. It's best to start with new brass, though I annealed some old brass and didn't lose many cases in the process. It's a fine and fun shooting caliber. We used 7.4 grs of 5744 behind a 46 gr gas checked cast bullet for fire forming and even got good accuracy with that load. Happy K Hornet shooter here for sure.
