Not really. Pic a pistol powder for your 9mm and a rifle powder for your .308.
375 Ruger is the NEW KING of the .375's. ALL HAIL THE NEW KING!
I did another test today:
22C at pretty much sea level.
Remington 700 heavy barrel 26" in 308 win.
USA brass (Winchester) all full sized to my gun. .002 bump. Trimmed to 1.995 then sorted to 157-158gr.
Sierra 168gr matchking HPBT seated at 2.875"
Fed 210M
All powder charges thrown on a Chargemaster lite and trickled on a RCBS 5-0-2 scale. Which has been checked against other scales and weights.
Labradar speeds
15 shots each of 42.5grs.
2 foulers at start of range trip. Allowed to cool for 30m untill it was this guns turn. Then allowed to fully cool before the next powder group
IMR 4895

D4895 current Lot 1459

Prehaps a slight accuracy edge to the D4895. Could be as that is my standard load. Both shot 5-3 round groups under 3/4" 100yds.
Faster or slower?
It's great powder!
I will do a similar test with the D4350ssc next

^^^ It would appear that lot# of Dominion is a touch faster burn rate than the IMR.

Good test. Looks identical. Almost loads identical. Almost.
Did somebody tried Dominion 8208BR versus IMR 8208XBR? And if someone did, what are the numbers?
Thanks
I haven't tried the IMR flavor but i worked up a load with D8208 with a 75 grain hornady BTHP for my 223 and it shoots well. Meters beautifully. Well below the hodgdon listed max before i hit pressure in my rifle so work up slow.

For those who wanted to know, comparison of IMR 8208XBR vs Dominion 8208BR. Same extrusion size but cutted a bit shorter. And IMR is yellowish, Dominion is gray. Here are the results.

In conclusion, Dominion is hotter than IMR, but it is also more stable than IMR.

For those who have been messaging me and who ever else is interested. I will run test with the D4350SSC. Just which cartridge are you more interested in? 6.5 creed or the 300 win?
You meet the nicest people on a Honda!
I would welcome results in 300 Win... I was considering a switch to the D4350SSC to test it out, but figured I need to work out a few other things with my remaining IMR 4831 before I can start comparing powders...
