As to rl powders not being good at long range because of a supposed sacrilegious temp. sensitivity, all I can say is I've almost always got the best speed, accuracy, and uniformity with reloader. And it real world testing, the variance between high and low is usually less than hodgdon. Rl22 is all I shoot in my 300win browning a-bolt lh stainless stalker. I've got around 2 kegs just for that rifle.
7828ssc is slower than both H4831 an RL22 and is most definitely capable of full pressure in the 300 WSM.

I'm talking about overbore 50 bmg type powders and 25, retumbo, etc. And 7828(I don't use ssc) and H4831 are to close in burning rate to care the difference.

Better check the burn rate chart. http://www.hodgdon.com/burn-rate.html

7828ssc is actually closer to RL25 and H1000. In a side by side comparison with 210 Bergers loaded to max pressure in my 300 WSM with H4831sc and 7828ssc, the H4831sc max charge is 65.5 and the max 7828ssc charge is 67.5 and the 7828ssc load produces 50-75 more fps. Both powders are plenty capable, but in the 300 WSM the H4831sc is at its best with bullets in the 180-190 grain range. For the 200-230 grainers in the 300 WSM the slower burning 7828ssc is a solid step up in performance.

Curious as to what kind of velocities you're getting out of the wsm with the 210 Bergers? Do they start off with enough velocity to carry enough fps out to your max range? Does Berger provide any info on what their functional velocity is, or anybody here done any tests?

I push the 210s at 2850 fps and I can safely push the 230s at 2710 fps out of my 24" bbl. The 210s and the 230s both maintain 1800 fps to 950 yards at my hunting elevation with the MV mentioned. The 230s carry about 200 ft/lbs more energy than the 210 at that distance.

I really don't care as I've gotten away from both after I saw how high you have to run the pressure on crappy single base powders to equal double base velocity wise. I can scan in some graphs from my last 7stw if I can find them. I got rid of the rifle and purged the data pretty well so they may be gone. On my 7stw 7828 and rl22 took the same charge weight to make the same speed on a 140.
I really don't get your quibble as I wasn't arguing about whether 7828 is a suitable powder, only that you shouldn't get much slower than that in a little cartridge like the 300 wsm. For cripes sakes, my dad has one in a pistol.

Mine shot the best with Hornady 165 to 180 grainers with RL17 and H4350. 65.5 grains of H4350 with a CCI250 and a 180 SST in Win brass at OAL 2.855 this was a one hole load at 2950 fps with my Abolt. BTW H4350 worked with every bullet I tried in my Browning.

I believe you're on the right track with the powders you're using. The only thing I would say is concentrate a little more on finding a seating depth before you get too experimental with powder. You're going to be jumping a good bit. My method was to find the sweet spot for powder and then tune the seating depth in from magazine length in .020 increments to 2.800. I always found a load in there that worked.

Another good load for me was 168 Nosler Etip on top of 67-67.5 grains of RL17. this should get you to around 3200 fps with good accuracy once you find a seating depth. Mine liked 2.820 with the Etip in this load combo.
I had heard the WSM calibers did away with the throat for less jump to the riling.
