1. H1000 burns cleaner than Grand. Grand is cleaner than Hornady Factory ammo.
2. H1000 was a little faster than Grand with the same load.
3. Grand SD and Spread were much better than H1000
I used a digital Lyman powder scale to measure 74 - 76 grain loads in .5 grain increments. I only used exact measurements. If it was +/- 0.1 grain or more I dumped and dispensed again.
