Scored this cute little Winchester 43 that I learned on first firing was no longer a .22 Hornet, but a .22 K-Hornet (The barrel is properly marked now )
Been fire-forming cases with gifted ammo while I wait for the dies to arrive. Going to be shooting the NOE TL225-52-RF-BV4-GC, probably seated fairly far out as I appear to have plenty of room in both chamber and mag. Current thinking is that IMR4227 is the "on paper" powder of choice; 2400 and Unique are both also possibly on the table.
But in the current shortage-driven practice of waste not, want not, I figure it's worth asking what others have already learned. Gotta stretch those resources.
