The only lead bullets I use for rifle is Missouri bullet company (308) but they don’t make 22 cal. I have no idea where to go but I know that Hornady makes 22 cal gas checks.
Lyman makes the following molds for 22: 225438 225415.
I would also suggest getting Lyman’s cast bullet handbook.
One question, what are you shooting these in. I would not recommend them in an AR.
