I've been using Accurate 2015 in place of 3031, it might be a little faster, good in the 45-70, 32 Special, many others, measures very nicely. H322 works well for ' full-power' loads in the 3031 range, but isn't advised for lower pressures. Full loads of H322 go MOA or less in my 444 with Hornady 265 FP. H322 also measures very well.
