Range Report Alliant 2000 mr temp stability report .308

[Aimsmall55]

Load was 47.5 2000 mr and 175 vld. Lapua brass, fgm210 m, 2.830" out of a GA Precision Crusader. 22" barrel.

Temp 76 degrees. 10 shot string with a 2734 fps average. 11 sd.
Temp 54 degrees 10 shot string with a 2709 fps average. 8 sd.

All sub moa

First off, this is my new go to powder. Varget has been replaced. Secondly, as far as pushing BIG bullets in a .308, it's the best I've seen. Temp stability is really there and is on the level of varget if not better. Something you rarely see in Alliant powders.

Not a huge temp difference, but interesting. Throw some in a cooler with some handwarmers or something, I'd like to see the same info but around 40 degrees and 90 degrees. Kind of like load development in March in the NW and shooting a match at Rifles Only in April.

Good to hear, I'll be heading to the range shortly with my 700P to try 2000MR under 178gr AMax's. Our temps here go from the 40's in winter to the occasional 100+ in summer, so I hope it's going to produce a load that'll work year round.

I'm seeing pretty much the same thing with my testing of 2000MR with temp changes in my match gun. It seems stable, very accurate in my rifle, and the speed is awesome. If this keeps up as the temps go down farther I will be switching my other rifles to 2000MR also. Further testing is needed but very promising so far.
