Favorite powder for the 300WM?

[actionshooter]

I'm going to try the 200 Accubonds in my 300WM, not sure which powder I should go with. I have cans of IMR 4350 and 4831 which I was using for other calibers.
Any suggestions?
Thanks Steve

H-1000

I use 200gr Accubonds with IMR 4350 in my 300WM. I run 68.8gr @ 2850 or so fps. I have gone as high as 69.0 gr @ 2950, but brass life was only for 2 shots or so. As always, start with a lower load and work up. All bullets are seated to fit in the magazine.

R22

R22 can be very accurate , however lot to lot variance can be a big deal.

IMR 4350 is good up to 180 wt. bullets

H1000 good 200 gr. bullet wt. and up

180 grain bullets - IMR 4831
200 grain bullets - H1000

Reloader 22 gave me the best mix of velocity and accuracy, but H 4831sc was the most consistant-just a little slower then R22. I have some H1000 but have not tried it.

I have used H4831 forever, still puts 5 into 3/4ths inch groups. If I was starting out, I would have to try R22.

Good hunting. LB

I like H-1000 in my 300 it gives me an extreme spread of 5 fps with winchester case's fed. 215 primer 180 gr.TXS and 81 grains of H-1000

I haven't been doing it all that long but for me so far IMR 4831 and 200gr Accubonds are the best load.

H4831 SC seems to be the go to accuracy powder with 200-210s in the LR BR game. standard, no magnum primers.

Thanks for the great response! H1000 seems to have quite a few fans.

Bounty Hunter, Why not the magnum primers? /ubbthreads/images/graemlins/confused.gif

Also, I have a 3.613 OAL, thats .030 less than the lands, does this seem long? Its quite a bit longer than the 3.340 listed as the SAAMI OAL. It needs to be a bit shorter just to clear the receiver while ejecting unfired rounds.Though it works in the mag.


Thanks again for the help! This is a very valuble site.

RL 22 AND H 1000 OR H450 IF YOU CAN FIND ANY.

Retumbo and reloader 25 both work good for me with heavy bullets.
