300 WSM Powder suggestions, where to start?

[DartonJager]

Am going to start reloading for my Tikka T3 light SST/SYN 300 WSM with 180gn Accubonds and presently have on hand the fallowing powders;

IMR-4350
IMR-4831
IMR-7828
H-4831
H-1000
RL-19
RL-22

I have read in countless postings that RL17 is among the best powders for the 300 WSM with bullet weights from 165-180 grains, but the only place near my home that has it available OTC wants W/tax $47 a pound so it's out till I find it cheaper.

What I wish is suggestions on which of the powders I already have on hand is best suited for reloading the 300 WSM and I should begin with it. I would like to give VV powders a try one day but the slowest burning VV powder I can find OTC is N140, WAY to fast to be used in the 300 WSM.

I have Federal and CCI magnum LGR primers as well as FED/WIN/CCI standard Lrf primers on hand.

Lastly considering the list of powders I have on hand would I be wise to buy some H-4350 to try as well or wait until the others prove unsatisfactory? H-4350 is redly available near my home.

Thanks for your time,
DJager/Art.

I have used H4831 with great success 180 bergers 10-12fps variability great speed

 

[velvetant]

My buddy uses H4350 with a Nosler 180 BT

 

[BountyHunter]

RL17 for up to 180 grains. Really shines with the 165-170 class bullets.

H4350 or MRP for 180 plus.

You will not go wrong with any of these.

 

[Barrelnut]

I have used RL-22 with good success with 180 gr bullets. Was very accurate, gives about the same speeds as H4350. I use H4350 the most for the temp stability and because I use it in a few other cartridges.

 

[DartonJager]

Thanks for the replies so far. I will try out H4831 first. The guy at Cabela's told me they're going to run an unadvertised in store only 20% off sale on Hodgdon powders soon. If I'm in the store then will pick up a LB of H4350 as it will only be about $24.

I have a Sako 75 in 300 WSM, so you're Tikka should like these loads. Get RL17 and HV100

180gr Accubond, 65.5gr HV100, Nosler Brass, WLRM primer, 2.86" COAL, 3025fps
64.5gr RL-17, everything else the same, 2997fps

200gr ELDX, 62.8gr RL17, 2.855" COAL, 2950fps

 

[Clucknmoan]

My Sako likes IMR 4831 with 180 Accubonds, RP brass and WLRM primers. Shoots them very well at about 3020 fps.

If it says "short mag" there's only one direction to turn... H-4350 ... End of search and story !!!

 

[Dosh]

DJ, we found H4350 to shoot bug holes with 185 Bergers in my friend's 300WSM. Tried several other powders, but the H4350 was superior. H4350 is hard to find here, the new Enduron IMR4451 is a temp stable substitute per the burn rate chart. Good luck

 

[DartonJager]

Thank to all who were gracious enough to help me out by sharing their experience with me. My research keeps coming back to the fallowing five powers in order of popularity:

Tie with H4350 and RL17
Tie with H4831 and IMR4831 and IMR4350

I will be buying a pound of H4350 VS RL17 for three reasons. #1-I've read to many chronographed confirmed reports of RL17 being temperature sensitive and I want a load that will perform consistently as possible, I realize no powder is immune to temperature, but Hodgdon powders are definitely much less susceptible VS Alliant and #2-The ONLY place by me that has RL17 available OTC wants $44/lb W/tax. #3-I already have the last 3 listed.

Once again,
Thanks a great deal to all who helped me in my powder choice.

I went through primer and powder tests with my .300 WSM in 2015 but with 215 Berger. The best velocity and group compromise using WW brass and 9 1/2M are as follows

1. RL-17
2. Magpro
3. IMR7828SSC
4. H4831SC
5. H1000
6. H4350

Good luck!

Don't overlook the new RL 26. In searching for a powder to use on another build I'm doing I found this powder had great reviews from guys using it on the 300 wsm. It apparently gave better velocity and great accuracy over their other powders.

Agreed. I remember when you were working a few of those up Feenix.
I was using RL-17 with 180 Accubonds at light speed, but the brass life was Really short!
That stuff has a pressure curve that goes from flat & boring to STRAIT UP in a hurry! But if you want blistering speed with a 180, it's the ticket. But yes it is also somewhat temp sensitive.
Fun to play with, but I moved on to 190 LRAB's over some Magpro & never looked back. Shoots bug holes & has a decent BC for the games I play Mr. Darton

On a side note, I almost looked you up a couple years ago while I was in Montana working on Malmstrom AFB with Granite, Feenix. Wish I had.
Back home now. hope all is well.
