Jeff, I have never heard of a .22-30-30. Is that the barrel marking? I assume it was originally a .22 Hornet? I have a Hornet barrel re-chambered to .219 Zipper which is a .30-30 case necked down to .22 caliber. Maybe some of the other readers can help you. You also might Google .22-30-30 to see what pops up. Please share your info with us and please send a picture of the barrel markings. Good luck on your hunt for loading data. Garnett
I just googled .22-30-30 and P.O. Ackly had an Improved version with a 40 degree shoulder. It is NOT the same as the .219 Zipper.
