I've got one 300 win mag that just likes H4831 powder, no matter the bullet. I've used 180 gr Accubonds in the past and I now shoot 190 gr Berger's in it. I won't tell you my charge because it's several grains more than max loads in the guides, but it works without pressure issues in this gun. Other powders, R22, H1000 and a couple others I've tried have not had the same accuracy in this gun.
My other 300 win mag I load a 180 gr Sierra GK over 71 gr of IMR 4350. Just a little over 3000 FPS.
R22, R23, IMR7977, H1000 would be a good starting point with the 200 gr bullets IMO.

IMR 4831 also works well in a 300 Winny. I loaded 180 gr Barnes for a friend of mine's A Bolt using IMR 4831 with good accuracy and velocity.
But DO NOT substitute load data for H4831 for IMR 4831.

I’m with Jtb51b. That little orange IMR bottle works for my 300WM as well. 208 gr ELD-M’s through my daddy’s old A-Bolt produced 3/4 MOA with the first load I tried. I experimented with 212 gr. ELD-X’s and got similar results. I bought some H1000 but haven’t bothered to try it yet.
I’m interested to hear about anyone else’s success/failure with heavy grain projectiles as well. This is good news. I’m going to start out with my IMR 4831 and see what happens. I bought two jugs of it last year just because stock everywhere was low and it was on the shelf. Thanks for all the input y’all
