Let's hear some 300 wsm loads

[Sodbuster]

"My go to Load is 65.5 W760 with a Fed215 primer and 180gr CT Failsafe (dont' make anymore) but I bought a ton of them years ago......too many one shot kills to remember on about any big game out there (Moose, Elk, Deer)"

I still have some 30 cal 165grain Failsafes as well. Not a high ballistic coefficient type bullet but they have put some of the largest holes through animals I have seen.

69.3 grains of RL26 is good for 3010 fps with 200 ELD-X in my 26" 300 WSM.

 

[PanhandlePilgrim]

Here's a group of 3 at 100 with a 195 Tipped Matchking at 2950fps and an SD of 3 using 68.3 gr of RL26. But I ended up going with the Berger 215s at 2838 avg for 1/2 moa accuracy and an SD of 4 over 66.5gr of RL 26 that held its accuracy out to 1278yds.

RL 19 pushing an Accubond 180 my rifle loves it

I load for my friends .300 WSM RL-17 and 180 GR Accubonds.

 

[TwoTikkas]

So who publishes the most complete data for the 300 WSM?

 

[SwampRocket]

I’m in the beginning stages of loading the 180 Berger elite hunters with H4350. So far, it looks very promising.

 

[jnordwell]

Mine like IMR 4350 under a 200 gr accubond. I believe it’s .5 under max. Cloverleaf groups...

 

[HookUp]

How many FPS?

 

[Wrench]

If you end up wanting some more brand new already chamfered never fired Bertram brass let me know. I got a bunch atleast 150 I’ll sell at $1 a round or if anyone else wants some as well.

I will say RL-26 has gotten me 3180 fps with 178 eldx and just over 2900 fps with 212 eldx from a 24” barrel 300 wsm.

Have you loaded any out of the lot you're selling? I bought a hundred and fifty of them and a bunch of them are JUNK. I would like to give it another try, but I'd rather buy from an open package that has a lot history.

 

[Wrench]

Rl17 with 180gr, rl26 with 210 and 215. 7828 did great in mine also.

 

[Conrad]

What is your barrel length and are you loading in a short action with the 215 pushed down into the case?

Thanks!!

H4831sc has pretty much been my go-to powder when I’m loading for the 300 WSM. Done load development for quite a few of them and tried about everything and for some reason it just seems to work in about all of them with 180-215 grain bullets.

What he said..... 180 NAB were what I settled on.

Any updates? Got a new tikka t3x superlite and plan on feeding it 175gr LRX in Norma brass, cci 250, and sta-ball 6.5, h4350, h4831sc, hybrid 100v, or superformance. Loadingvto mag length. Anyone have any luck with these?

I use that bullet with 760 and it's lights out

300wsm 175LRX Norma 1x fired, FEDGM215M, 2.090 case trim length, 2.175" BTO gives .11 jump, with Staball
65.8gr = 2990, 2992
66.8 = 3068,
67.8 = 3087
68.2 = 3105, 3101
68.6 = 3118, 3108
68.8 = 3112, 3121

300WSM as above 68.2gr = 3082, 68.4 = 3105, 68.6 = 3111. I shot 68.4

300WSM:
Staball at 68.4gr, FEDgm215m, Norma case at 2.090", 175gr LRX at 2.175"BTO, 3100fps 23" Xbolt


From a few posts in this thread

 

[DMadsen]

LRX 175, Norma once fired brass, WLRM primer, using 64 Gr. H4350 seated .05 off the lands through an X-bolt 23" barrel : average velocity of 25 rounds was 3023.

 

[Jusgunn3]

168gr ttsx, 66gr RL17 and I shoot it at Elk, bear, dear…

 

[Tuby27]

Tikka t3x superlite 300wsm, Barnes 175gr lrx, seated ogive at 2.234 to fit in factory mag. Staball 6.5 at 67.5 (stiff bolt), 67.9 (stiffer bolt), 68.3 (super stiff bolt). Outside temp was about 35-40 degrees, overcast, some fog at times, southeast wind, at about 4300ft elevation. Caldwell Chrono was useless due to over cast, first shot was 67.5gr going 3100fps, second shot 67.5gr going 3938fps…so yea, not going off that. But my question, if any of you experience, did you guys show pressure signs at/about 67.5gr., I had a stiff bolt and bolt marks on the brass, fatten primers. When I got home I pulled the rest of the projectiles and noticed the powder was clump/stuck inside the case. Tapping it didn’t break it apart, I had to use a paper clip to break it apart to pour it out of the cases. You can see the chunks in the pictures. My suspicion is that it’s due to the cold temps. Any ideas about it clumping up also? Thanks.

How close to the lands is that?
