    I'm working up a load for a 300wm 185VLD berger. I read some reviews and settled on RE-22, but am not sure about temp sensitivity. The re-22 seems to be the choice for 185gr bullet. H4350 seems to be the choice for 165 grain and lighter. H4350 seams to have better temp sensitivity. Anyone have experience on which one I should choose? Thank you!

    Rl22 has been great in the 300 wm with 180s for me as has h4831 which has a similar burn rate and is an extreme powder so much less temp sensitive. Anything over 180 and I usually go to h1000 which is also an extreme powder.

    RL22 is usually a great powder around 74-75.5 grs, but my 300 loves 68-grs of H4350. Unless you hunt below 0 or above 90 I would not worry too much on powder sensativity. I have used RL 22 here in NM from 20-90 with no issues and 20 fps highest spread.

    Good luck!

    If I had to choose one powder and only one powder for everything I own from 25/06 to .338 WM and just about everything in between it would be H-4350.. for whatever reason it seems to give the best results for me... it burns clean, velocities are almost as good as the slower powders, and accuracy in my guns always is best with H-4350... I am a firm believer in H-4350 and over the last 45 years of reloading I've noticed that just about everything else has disappeared from my racks of powders and the only kegs I buy these days is it. In the 5 300 WM I load for it is always the best powder with 150--180 grains and also I use it in all the short mags I load for also. great powder and nothing against R-22..

    I use RL22 with 165 Accubonds in mine, and am currently working up a load with IMR 4350 and the 185 Matrix VLD (didn't seem to like RL22 for whatever reason). Also have some 210 Matrix VLD's to try out maybe with RL22 or 25? Marshall doesn't recommend the 210's for hunting, but should be an excellent LR target bullet.

    rl22 is a great option for 180 grain bullets in the 300 win. But if your rifle is bent on single base one of the 4831's, h1000. or retumbo will be the best choice. I've worked with 4350 with heavier bullets in the win, and while it's accurate, it will hit max. pressure earlier and not net as much velocity.

    I see the new Nosler #7 H1000 is now listed as one of the most accurate powders replacing RL22 from #5, #6. I might need to buy some. Don't rule out IMR4350 either with 165-180's.

    i,ve used both have a great load for a 308 norma with h4350. used rl 22 in the 300 win with great results. another powder, to look at is ramshot's magnum. use it only now, in my larger cailibers. very good in different temps, for a ball powder. check barnes web site, tested this powder, and a few others for temp, and it did the best, along with h1000.

    ill throw a diffent one in the battle. My go to powder for 150s and 165s in the 300 win mag as allways been re19. It seems to win the accuracy battle in every gun ive tried it in. It works with the 180s well too but re22 or 4831 will net you another 50 fps if that matters to you. Ive allways said that if you take a 300 win and load it with a top end load of re19 and a 165 nos bt or a 165 sieara prohunter using a fed match mag primer and it doesnt shoot moa with one of those two loads the gun probably will never shoot moa.

    everyone forgets about rl19 unless they are throwing heavy stuff in an '06 type case or feeding a 338. rl19 is a good powder.
