    I'm running H1000 and Retumbo.

    I've used RL25 and the one I didn't like was N165.

    To begin with there is no "best" powder. It depends on your rifle and your bullet selection. If you are running a 1:10 then you will be better with the 250gr smk's. If you are running a 1:9 twist you will probably do better with the 300 gr pills such as the smk's or the scenars. I have used H4831sc with 250 SMK's and they shoot well but... My Savage with 1:9 twist loves N560 with 300gr Lapua Scenars, shoots .3's consistently.
    Your rifle will tell you what it likes and will almost always have (2) accuracy nodes one high and one low. Retumbo, RE25, H1000, and Us 869 are some others that I have used but did not like the consistency or cleanliness of powder burn. I will be trying N570 as soon as it comes available to reduce pressures that powder show such as the N165, and H4831SC. I shoot at least 20- 30 rounds each week thru my LM. Good shooting and remember... Start low and work up slowly.

    Vihtavouri 170 for my lapua,used h1000 and wasnt the happiest,the Vihtavouri 165 only produces results with my 250g and my 225g rounds. But for my distance (1200+) Its the 170 with 300 g berger hybrids for me, as said before there is no "Best" powder. You can buy identical rifles and one might like a specific combo and one might not. They are kinda like women :lol:

    Three of us run AI AWSMs and use AR2225/Retumbo under 300 grain Scenars ..... getting .3 three round groups and .5 five round groups at 100 meters. (Lapua brass and Federal 215 Magnum primers)

    We have noted that the Scenars like a BIG jump .... 70 thou/1.8mm ..... :shock: this is fortuitous because the AI magazine length restricts the OAL and at maximum mag-length it is a 40 thou jump.
