Has anyone found data as to where Grand rates on the temp stable chart? FPS vs temp.300 PRC virgin Lapua brass, Federal Match 215M primers, Hammer HHT 203 grain, Rifle is Christiansen Arms Mesa LR 26" barrel 1:8 twist
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.
