When I had a 22 Hornet, later converted to K Hornet (which is well works the effort BTW) then Lill’gun was ‘it’ after trying a few different powders, so that is your call re. Using Vit powders (also h110 was pretty good).
Other than that the Lee factory crimp die ( https://leeprecision.com/factory-cri...22-hornet.html ) made a significant improvement on accuracy, the thin cases on the Hornet and long taper.
