Recommend some powders for 300 WinMag

What are some good powders for the 300 Winchester Magnum?

Looking at bullet weights from 150gr to 200gr. Primarily for longer distance shooting.


Thanks!

RL17 / RL19 / RL22 / N550 / MRP / H4350 / IMR4350 / W760
You're pretty seasoned, so should know all this. Big difference between 150 and 200 grain loadings.
What's your barrel length?

Never loaded large rifle calibers... 30-06 being biggest and didnt find any info for 4064... Out of my league a bit.

Barrel is 24"

Mostly loading 200gr eld-x bullets... But I have a lot of 150gr and 168gr bullets around for my -06... Want to have some versatility not having to have two powders on hand for the WM

If you want to come down to Beaverton, I have some RL19 & 22, IMR4350, N550 & N560 you can try. I'm low on W760 and out of MRP.
RL17 wouldn't apply to the 200's, 19 might be a bit too fast too.

H1000 with 190gr has been very solid for me.

Take a look at Nosler's reloading data. I use their numbers and apply to other brand bullets of the same weight. Due to the bearing surface, the actual values do change.

I would stick to burn rates that are no faster than H4350 or RL19. I use a lot of H4831. RL22, RL25, H1000, IMR7828, Retumbo
