One of my favorite loads is 60gr H4831sc with a 129LRX.

Thats a nice target 338 dude, pretty sure I'd just stay with your combination of H1000 and the 185 juggs! Be hard to improve on that much more!
I too am curious about the stability, and will test it. However I'm not too afraid to add or subtract a few tenths of powder to maintain a desired velocity or node. But in order to do that, you got to know your loads and test them!

This! It is a month before fall hunting season when I finalize my load development. During hunting season, it is, on average, 10-30 degrees colder.
As mentioned above, I stopped worrying about temperature sensitivity for a long time. I used to be a strictly Hodgdon Extreme powder user. I still use them, but I conduct my load development and consider the environment in the hunt area. As with anything else, YMMV.
Yes, only threw that in there because of the one post that mentioned the 185 juggernaut that is the bullet I use in my 300 win magthat's cheating, you used h1k

Thanks. That's a factory stock, Winchester Model 70 Super Grade, with the French Walnut. The Super Grade Model 70's being built these days are very nicely made.

Yeah well when I go to WY, or even here in VA temps can very 40 degrees in a day, or during a day. So I don't screw around with powders that are not temp stable, just to get 20 to 50 fps. If it's not RL16, H1000, H4831sc, or H4350 I don't use it in my Hunting rifles. But that's me, to each his own. RL26 is another 1 fps per degree powder. Found that out in my 7mag. Got load right for WY, week before I leave I check it and it lost 30 fps from 80 to 50 degrees. So I scrambled and got a H1000 load that was 50-60 fps slower but 10x less temp sensitive. And it was slightly better moa and ES wise as well. H powders are the way to go imo. But RL16 is great too and not hateful at .3 ish fps per degree, for intermediate range loads.

Ah, a 1949 Model 70 is a pretty special rifle. Best of luck with it, and with finding a stock you like.
Regards, Guy
That's why Bryan Litz clearly noted to make sure to factor the environment of your load development and where you are going to shoot it at ~2:20 minute mark.
I ran one of my loads - 215 Berger at 2850 FPS out my .300 WSM using the average altitude from where you @ ~1000' and Belle Fouche River (lowest altitude in WY) @ ~3100' and below is what I got.
1000' @ 80 F; @1000Y = 1749 FPS/-262.92" drop
3100' @ 50 F; @1000Y = 1785 FPS/-258.64" drop
I am showing a gain of 36 FPS gain at a 1000Y.

Shooting 215's with magpro in my winmag. 77.0gr I believe. Could be 76, but I think it's 77. Norma brass, 215m, seated at 3.650" runs right at 2,900 from a 26" bartlein.
I've never been able to get it into single digit sd's though. 11-13 is about the best I've seen. Es in the 30's. Consistent hits on 12x20 steel out to the 1,000 yard mark though.
Haven't shot 7828 in this barrel but in my last one it was not uncommon to see sd in the 2-5 range.
H1k in this barrel has done good but I'm out of it now and I'm sitting on 7lbs or so of magpro.

Litz is smart, Applied Ballistics is pretty spot on and corrects for environment perfectly. I've checked my dope at ~ 8000' 40Ā° in WY after load development at 675' 50Ā° in WV and it was dead on, at 475 yards with a FV 25 mph cross wind.
