I just bought a bunch of these after giving them an initial try in my rifle.
I'm using these bullets in my 308 Win bolt rifle. It's a 24 inch polygonal rifled barrel. I'm using virgin Lapua cases and Fed 210M primers.
I've tried Varget and Re15 to near compressed load levels and can't seem to get much over 2900 fps before things get sticky, varget being the slower of the two powders I've tried.
Is there another powder that in the opinions of the learned might prove better?

This is not my strong suit, but most of the fullbore shooters I know down here used faster powders for the 155gn bullets in the .308. You might want to try Hodgdon Benchmark, I can give you starting loads if you want.
BTY, don't you mean Varget being the FASTER of the two powders you've tried?

Just back in from a Long Range rifle class. I was an assistant instructor but got some time to test the 155's out to 710 yards.
I changed the load a bit and used 45.0 gr of Reloader 15 in Lapua cases and Fed 210M primers with an OAL of 2.875. Average velocity is near 2875 and the primers a little flattened.
Accuracy was very good and the elevation is several minutes less at longer ranges than the 175 Sierra's I've used in the past. As an example, at 710 yards I had 16MOA elevation and 8 minutes wind (windy day). At 670 yards I used 15MOA elevation, 580 yards was 12MOA and 440 yards was 7MOA. I use a Leupold Vari-X III M3 Long Range and am limited to 1 MOA elevation adjustments. (The 710 yard elevation of 16MOA is about 3MOA less than I've used for the 175 Sierra, this is about 21 inches less drop.)
The actual data tracks very well with the predicted data for a .506BC at 2875 fps, temp at 60(f) and altitude at 2620 ASL.
There's not much savings in the wind department over the 175 as they both 'buck' wind pretty well.
Sorry to offer confusion, I was talking only about the velocity of the bullet based on the two powders used not the powder burn rate. I may switch to VARGET for another test but the RE15 is doing very well with accuracy in the sub .5MOA area with these bullets and once fired cases.
