Powder for 300 wsm

[Plowboy85]

I have some RL17 and H4350 I'd be willing to let go of a couple to help you out.

This is what I am using for my 300WSM's Good for both Elk and Mulys. Last Elk taken at 387 W/ Range finder 1 shot, Last Mule deer taken at 480 1 shot.

I have used N550 for years in my .300 WSM on our elk hunts. It performs very well with the Nosler 180 partition.

I've got around 3 lbs of this.and have some 178 eldx and 185 berger classic hunters loaded up to hopefully try out this week end

I use superformance

How do you like this powder? And how temp sensitive is it?

I have tried 4064, with no joy, 4831 imr or H will work just fine in 150 to 180 group of bullets. OAL will be critical in the loads i tried. 50 for Barnes and 25 to 30 with everything else. This has worked for me and my 2 wsm's. Just my 2 cents worth.

 

[derfssor]

4831 both IMR and H has worked fo me. I have found that OAL was very critical in the 2 WSM's i have. If using barnes, 50 to 60 off lands and 25 to 30 with everything else. This worked for me and just my 2 cents worth. Good luck and have fun.

in my Kimber Montana 8400 7WSM RL 26 sends 150 gr Hammers out at 3350 fps into one ragged hole - have shot faster but this was most accurate pressure free load.

For the light weight projectiles H380 has done very well for me out of a Savage 110 bear hunter. Tight groups and great speed, zero issues

I am playing with 300loads now. 205 Berger EOL's though. Did ladders with N565, 7828SSC, and IMR 4831. It definitely likes IMR 4831.

180gr Accubonds with 68.0 gr of RL 22 has produced this group.

H4350 with 180 accubonds here.

Looking for recommendations for powder for my 300 wsm for 150 to 185 grain freedom seeds.ive looked everywhere trying to find any 4350 type powder with no luck. I have found imr 4955.magpro and superformance and imr 7828ssc powders instock are these good powders or should I keep looking? Or what would you suggest Thanks

I just put together a 300 wsm and developed a load using N550. 62gr pushing a 180 cutting edge lazer at 3058fps with Norma brass out of a 20" 1:10 barrel. It's shooting decent but I think I could still refine it and get a tighter group.

I like IMR 4831 and Reloader 17 with 150-180 bullets. I am using Reloader 22 with 190 in mine and getting 3,000 fps with it. Reloader 26 will push a 190 up to 3,150fps, but the extreme spread was over 80 fps. Reloader 17 is similar to IMR 4350, but it will give higher velocity.

I use superformance

Does anyone have a good load for Superformance loads for a 300 RSAUM? I asked Hodgedon and the technician said no data available.
I know that the OP is asking about the WSM but I just started working on a project with a Remington 700 LTR 20" barrel and 166 Hammer Hunter bullets.
