I have always used IMR4350 with great sucess. I am sure H4350 would be equally good with a 130gr bullet and add the benefit of better temp stability (its also currently unobtainium). I will be trying IMR 4451 to see if it runs with my 4350 loads as that is right in the same burn range. I noticed that Midway had some Shooters World SW4350 you could try.
