The nice folks at Hodgdon Powder Company have a good website with most of the modern cartridges listed and Varget loads for many of them. I have a sneaky suspicion that the 22 High Power is not on their current list, but go to <hodgdon.com> to check. Then if the powder and/or cartridge is not listed, they have been very accomodating in responding to e-mailed inquiries.
I had a similar question with Varget and my 250/3000 and they gave me special treatment. I think they are setting a high standard and will likely help get you shooting your High Power.
The Loaddata site is pay for play, which is OK too. I'm glad that Hodgdon does their service to us shooters for mutual fun and enjoyment, making us knowledgeable customers.
