What's your best guess?

My manual is the Lyman 48th Edition. The powder I bought to try is IMR 4831. Manual says the max load is 72 grains. Think that might fill er up :wink: . :

Boy do I feel dumb right now. Just checked my reloading manual and it's a compressed load of 72 grains........for H4831. I've got imr 4831 and max there is 67.8... I've got to start reading more carefully. No harm done though, Haven't even started to load yet.
