Perfect. Thank you.

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.

Results below. Page removes spaces

Grand
Grains/fps/SD/Spread

74.5/2915. 2/5.4/14.5

75.5/2959.6/6.4/15.4
76/2957.9/16.2/47.6

H1000
74/2892.3/12.4/37.4
74.5/2926.6/20.1/57
75/2939.0/5.8/15.3
75.5/2968.7/20.7/65.3
76/2965.1/18/50.3

Has anyone found data as to where Grand rates on the temp stable chart? FPS vs temp.

Tomorrow I'll be testing Grand and H1000 again with virgin Lapua brass, Federal Match 215M primers and Barnes LRX 200 grain bullets. I'll post my results when I return. I'll redo the Hammer bullets when I get another box in.

As for metering, Grand is a spherical powder while the H1000 is rods. The Grand is smaller and easier to meter for precise loads. (Today I used my Lyman digital to get the load close, then a trickler with Hornady Precise scale that goes to the hundredth.) It was easier to get my loads from exact to 0.04 above. I could have gotten closer but was pressed for time.

It is supposed to be temp insensitive.

New to this forum. Anyone know how I can save this thread to refer back to? Gonna try load up Grand in my 300 WM with 175 Barnes LRX, soon.

I will be impatiently awaiting your results. I bought a jug of Grand for my 300WM and the 175gr LRX. At the moment I'm burning 73gr of H4831 under the LRX for 2966fps and tiny bug hole groups. I'd like a little more velocity tho
