reloading the 300wsm

[elkhunter35]

can anyone help me with this? i want to shot a 150gr. with h1000 powder but i can not find a powder load for this.

H-4350....that other stuff may be too slow for this little case and besides that it's dirtier than heck....

I tend toagree, H1000 istoo slow burningfor the light for grain bullets and you'd run into case capacity issues. I'd also start with the 4350's, then maybe 4831'sor RL19.

I loaded some in my 7 rem mag this year for heavier for caliber. I needed to keeping adding powder to get the velocity I wanted, using the chrono as the pressure monitor. I stopped at 72 grs which is6grs over the max from Hogdgon's data 160's, but it was the only way i could achieve 3000fps like other loads I have developed safely in my rifle. I tried itwith the140 tsx and felt it was to slow, accuracy was fine just not up to the MV the faster burning powders give. Low SD though in my somewhat limited experience with it as a propellant. If i were needing to develop a 160 or 175 load in the rem mag I would give it a go but I am so pleased with my 140 and 150 loads that it just turned out to be nothing more then an experiment, at this point at least.

I agree with the other guy's about the H1000. I use H414 in my 300WSM. 4831 is also a good powder, but I like the H414, I get better velocity and accuracy with it. Tom.

I have good luck with RL19 and Barnes 168gr TSX

elkhunter - Not to be critical but if you want to shoot 150 grainers you aren't getting the full potential of the 300 WSM. Of course, dependent on the game your after, you are hard pressed to find a better bullet ballistically than the 180 - .308 bullet - especially at longer ranges.
IMO you would be beter off loading the 150s in a .308 Win and stoking the WSM with 180s. The velocity difference between the 2 are not all that different.
