Ramshot Grand

The one thing Midway has been doing is having a clearance sale about once a month. I just got 8 -1 pounders for $27.95 a lb tags, title and tax came out in the $35 dollar range and only $223.60 dollars plus $hazmat and shipping. Its a good thing trying to develop and feed loads to 2 300 PRC's and a 300 win mag. Im averaging alround 80 rounds per pound. The good thing is these new recoil brake really work and help bunches. I shot sporting clay competition tournaments for years and have a pretty tough ole shoulder and have wrung out 35 or 40 rounds a couple times a week without any bruises. Im finding the Grand powder to be very accurate and burns as clean as any powder I have ever shot.
 
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.

good info. Did you hit pressure or see signs of pressure? What was the case fill/remaining capacity? Thanks
 
Great info. This will be helpful for a number of projects for me. Any apparent accuracy advantages? Were these 3 shot groups?

Accuracy was an issue with both. I think I've got another carbon ring and some fouling. Will know after my borescope arrives Friday. These were 5 shot groups, the Grand was a little better than the H1000 but both were within 1.5 inch. I still have some work to do for the accuracy.
