300 wby best powder and bullet weight

Hi what is your best powder and bullet weight for your 300 WBY

 

[Eagleye]

200 Grain Accubond or Partition IMR 7828 or Reloder 25

At a time I had the Accumark, tried lots of combination. I think I still have the data somewhere. but long story very short: Sold the rifle.

After you decide on bullet weight, I notice both Nosler 9 and Sierra V Manuals suggest a "best powder" and the most accurate loading of powders from their testing. I do not see similar in Hornady 9 or Speer 14. Lyman typically bolds their "best load", after you decided on bullet weight.

Unless they used your rifle, and you also know the brass brand they used, the primer that they used and their seating depth (jump to lands) - what someone else found works well in their outfit, means not much for yours ...

I think it’s more what you can find powder and bullet wise. Availability is tough these days. I’ve got a bunch of 220 Hornady ELD for my 300PRC. If you go lighter with bullet choice there are more powder options available.

Mine really likes 200gr bullets, Speer and Nosler Partitions.
For powder, I started with IMR4831 but have moved to Reloader 25 but both worked fine for me.

Big for bore projectiles......Alliant reloader, bigger number the better. Small projectile as low as a 4350.

If I had to pick only one.....say 4831. But that's just crazy talk, how could one not play.

I'm with Eagleye on this one 200 accubonds are the bomb

180-200 grain bullets. IMR7828/H1000/RL25

 

[bibatoad]

R-22

I have 2 loads I use in my .300 WBY.

The first is a 180 gr Accubond over RL22 and the other is a 165 gr GMX over IMR 4831.

Hi what is your best powder and bullet weight for your 300 WBY

RL22 or RL26 Or IMR7828SC with a 180 or 200 Gr-er ! You can get 3200 + with a 180 and 3000 with a 200 ! RJ

 

[freire]

180gr bullet and IMR 7828.

My 300 Weatherby loves 84.5 grains of IMR-7828, in either the regular cut or SSC version, behind the 180 Nosler Accubond or Partition. IMR-4831 worked excellent as well.

I load 300 H&H, not 300 Wby. My rifle likes 200 AB and either IMR 7828 or RL26. My hunch is that the higher case capacity of the 300 WBy will call for either RL33, N570 , IMR 8133 or Retumbo, with that same bullet.

That's my LOAD as Well ! RJ

Nosler 200 gr partitions over RL22. Works very well on pretty much everything. Also like the Accubonds in 180.- dan

I know, it works great! It's a German (Sauer and Sohn) Weatherby Mark V, with the 26" original barrel. I don't shoot it anymore, I just cannot take the recoil................. I mellowed down to the 300 H&H.

 

[Dogleg]

I sure end up using a lot of old style 7828 in the 300, 270, and 257 Weatherbys. Part of that is because I have so much of it, but its also hard to argue with results. Also had good luck IMR and H4831 and H1000.

If I've noticed one thing about the 300 Weatherby it's that its more about the bullet than the powder. If your barrel doesn't like a particular bullet changing powder is unlikely to change it much. If it likes the bullet, different powders won't hurt much.
