My best guess is 78-82grains will be max. Though I haven't tried h335 myself. The cases seem to bulge too much with super max loads. Making extraction via wooden mallet the order of the day. At least this has been the outcome for me.

I'm thinking 4064 or 4320 might do the full case but not sure if it will bulge? Tac certainly did when I tried 97.5 grains. Sure would be close..
