have you actually chronoed this? Because im shooting 66.5g of H4350 and 168g Berger VLDs out of a 24in proof research barrel and getting 2950 of my Magneto Chrono
That seems awfully slow. And im not sure how the other guy got 3k with 180s with the charge as low as he states. Im getting 2960 with 64g h4350 and 180 accubonds and 66g with 168 e tips produced 3080fps. Thinking about going back to them and seeing how fast I can go with them

Is there much difference (accuracy or velocity) between H4831 & H4831sc ?

It is the same powder. SC stands for short cut, it is just in shorter sticks so it packs into cases a bit better. You might get some performance differences if your powder is highly compressed with standard but not with the short cut.

even the Sierra manual is estimating 3100fps with 67g of H4350 and a 165g bullet. I think some of you are spitting out velocities without running through a chrono honestly. This ain’t my first rodeo. Claiming you’re pushing a 180g pill to 3100 with less powder than I’m using with a 168g to get 2950fps is hard to accept. Unless your shooting a 30in pipe. But even then...

I have chronoed every load. Id like to find one using 165/168s going 3100. My 180s I've pushed to 3000+ but backed them off. Not sure if you're referring to me but i never stated I shot 180s @3100. That seems unrealistic unless like you said, a really long barrel was used.

If the Sierra manual says 3100 fps with 67.0 grains of H4350 and you're getting 2950 FPS with 66.5 grains, it seems your loads are pretty slow compared to the manual.

From what I've seen, mid 2900s with a 180 accubond and H4350 seems to be the sweet spot for short action WSM's with 24" barrels.

From what I've seen you should be at 3100 or better with 66.5g depending on your barrel. Are you using magnum primers?

So I have a 22” barrel 300 WSM in the works. Was planning on still using h4350. Are there any powders I should think about considering I’m using a shorter than normal barrel for this caliber?

Depends on bullet weight. 4350 will still be ideal with 180 and 165 class bullets.

That weight class is an option but I was also considering the 200 gr accubond or LRX. Probably nothing heavier.

4350 will still work. Bench rest guys use it with 215s and 230s because it is consistent for them. You might get a little more speed before hitting pressure with 4831 and definitely will with rl26. I use 4831 behind 200 eldx in a 23” barrel. Shot so well I didn’t try anything else.
