Powder consensus - 300wsm 215vld

[mattlewis]

I've read through the threads and searched the world over. It seems that the consensus powder choice for 300wsm and the 215/230 is h4350 or 4828ssc if one likes IMR.

Is that an accurate statement? I read a couple rl22 loads, and a couple other powders that were samples of one, but it seems like 4350 was the most used.

Most use H4350 with the 210 and lighter bullets. I know one guy that shot really well with 4831SC with the 215. Usually they go a little slower for the 230. 7828SSC. A lot has to do with the freebore in the gun. Matt

 

[dragman]

Had great success with 215s and RL 17. And 230's answer RL 23 was good too.

 

[TRG300WM]

RL 17 worked well in my 300WM with 208 Amax
2960 fps chronographed load 27.5 barrel.
The best it shot was .450 at 100 yds out of my trg-42.
But H1000 is the go to, it just works so well.
Definitely give it a go the 300WSM.

I love and have H1000. Can you share your load and data?

You said WM, but I am shooting WSM.

I think it depends what you are looking to do with the gun ie (Hunting, tactical matches, benchrest, F-class)
I would either stick with H4350 or H4831SC.

Non-competition long range target shooting.

Non-competition long range target shooting.

That depends upon how far and how small you want to shoot. Matt

Yes i said 300 wm but it wouldn't take long to work up a good load for the WSM with H1000 power.
My 300 win mag uses 70 gr RL 17, fed 215 and a 208 Amax, gives 2960 fps.

Hornady Match AMP 225 grs 78 grs H 1000 Av 2809 fps
chronographed and compressed load in norma brass. max load

Might want to try Black Powder if your not shooting long range!

Non-competition long range target shooting.

If you want powder that won't change velocity due to temperature, stick with either H4350 or 4831SC. These two powders are used by pretty much everyone that competes at a high level in F-class that are shooting a wsm. H1000 is going to be too slow for a wsm (Yes it will work but the other two powders are better suited for it). I'm on my 4th wsm barrel, so I have a good bit of experience with the caliber.

Before you say your not going to shoot competitively, go check out or shoot a match. I see that you are in Northeast Tennessee. Oak Ridge has an outstanding facility for shooting f-class and other matches.

my load with 17 and the 208's is going 3065fps. I wouldn't push it that hard for competition, but works great for a long range target toy or for hunting. Killed a deer at 1071 with it this year.

 

[4xforfun]

First, it is the 215 HYBRID, not VLD. My 1000 comp HG LOVES the 215 Hybrid on top of H4350 and Fed 210's and a 1/-10 twist Kreiger. If LR is in your future, this is the ticket!!

Good luck,
Tod

Is not that .300 WSM one of those fat stubby short rounds designed to approximate .300 Win Mag ballistics out of a short action loaded to an COAL of 2.8 or slightly more like 2.9. I would guess that the chamber might be throated out to accommodate longer bullets for non short magazine length. If I had something like that I would go for H1000 or possibly IMR 7977. My powder selection would involve both burning rate and density. Possibly more IMR 7977 would fit inside the short fat stubby .300 WSM case, it also might meter better than H1000 that cuts and bridges inside my powder measure.

My own opinions are that loading a long .30 caliber bullet like the 215 in a .300 WSM would sort of like being seating a bullet way down into the case reducing powder capacity in a normal short action rifle. My .300 WSM loads used no heavier than 180 lead core bullets and 165 solid copper bullets. The 150 Barnes 3X tipped worked the best. H4350 was the powder of choice and velocities were about 3150.

Another (unsolicited) opinion is that the 1955 vintage belted .300 Win mag when loaded to recommended max pressures, about 61 thousand, provides about 2900 fps with the long heavy 208 Amax when loaded to fit inside a standard long action rifle and when this is done the bullet protrudes deeply into the case and is surrounded by powder. My .300 WM has an ordinary steel receiver and bolt and is throated for 3.45 COAL ammo, single shot and 75 grains of H1000 and the 208 Amax. To my best knowledge common ordinary cartridges do have pressure limits and I would guess that to be 63 thousand and possibly 65 thousand.

Another (also unsolicited) .30's for hunting and 6.5'smm and 6mms for targets.

I would never build one on a short action. I would do it on a long action so it can be throated out and still shoot the big bullets from a magazine if desired. Also you will be able to get the loaded rounds with longer bullets out the action without talking the bolt out. I shoot 1000 yard Br and it is one of the most accurate cartridges. It holds many records. The brass is extremely good. I shoot Berger 210 VLD's at 2850 with H4350. I can throat it out to .280 freebore and run a 230 Berger at 3000 with 7828SSC. Matt

 

[P72]

The .300 WSM would sort of look like a "King Cong" version of the much smaller 6mm Dasher in respect to proportional size - a fat stubby case with some long bullet stuck into it. Not being involved with long range 1000 yard bench rest shooting I will be content to observe same. I will continue to hunt with my .300 WSM that shoots like an ordinary .300 Win mag but is lighter and shorter - I guess the .300 WSM was designed to do this.

Short and fat is were it's at!

I am shooting 69 grains of RL26 and Norma brass with a cci250 primer. My barrel is a Schneider 5P, 1-9 twist finished at 27". Countour is a number 4 fluted. My velocity is 3050 at 4000 elevation. This is not a hot load. I have had it up to 71.8 grains but had pressure. This is going to be a Freeking Awsome hunting rifle with these 215 Hybrids going this fast. Accuracy is 1/2moa and better. Hate to be selling the rifle.

Is your chamber a standard short action
throat 300 WSM or the .280" for long actions ?
