I'm just starting to load for the .22 Jet again after a 40 year hiatus and finding load data is scarce. I'm loading Hornady 40 grain .222 bullets. Any help would be appreciated.

From the Hodgdon website (I have plenty of load data in my older manuals if you don't have any to refer to).

40 GR. HDY JET IMR IMR 4227 .222" 1.550" 13.5 2290 32,900 CUP
40 GR. HDY JET Hodgdon H110 .222" 1.550" 10.0 1892 11.0 2019
40 GR. HDY JET IMR SR 4756 .222" 1.550" 6.7 1925 31.200 CUP
40 GR. HDY JET Hodgdon HS-6 .222" 1.550" 6.5 1769 7.5 1883

I reload for the Jet using the same bullets, 11.5gr of IRM 4227 and Small Magnum Pistol Primers.

the above listed hs-6 load is what i shoot for my everyday load. i use sierra .223 bullets though. not a lot of noise and no problem with extraction in any of the jets. accurate enough to shoot peanut cans at 100yds. with too.
