Will H4350 or H1000 powders be suitable for the 185 gr or what would work better?
I prefer the slower powder myself. But 4350 sure does some impressive stuff in the 7mag/300mag. I'd go with H1000, Re22, Re25 or maybe even Retumbo with the 180 and bigger bullets. AND, don't forget 4831, 7828, or Magnum either.
All of the powders mentioned will work in the mag but I would stick to the ones that have the least temp sensitivity for long range stuff. We check barometer, air temp, turn necks, weigh cases, etc., etc. and powder temp can be a larger factor than any of the above for bullet drop at 1000 yds. The Reloader powders give some of thebest velocities but have the most variation due to powder temp. I would personally use one of the Hodgdon powders such as H1000, Retumbo, or even 4831 or 4350......Rich
I've been shooting my 300 Win mag scendero with moa accuracy out to 900 yards using 150 grain Hornady SST. I've tried loading 180 gr barnes tsx with terrible results, 150 gr noslers were so so. I'm doing a aoudad sheep hunt in texas in March and never killed anything with the sst, and have to wait til Jan for doe season here in Iowa to test em, any thoughts appreciated.
Have you tried any other barnes? I use 168gr TSX. You might try the MRX.
I use a Ruger #1 factory barrel, It's real picky about seating depth and charge weight/powder type, even brass affects consistency. If I do my load work right I can put three inside a quarter at 200yds.
I have gone trough femurs both front to back, and back to front on MT mulies, at 200-250yds. I have no doubts it would be fine for 400-500yd work on elk. It's way too much on my 300yd antelope, I wouldn't hesitate on sheep.

I've used the 180gr. SSTs in my 30-06 and had complete penetration on an elk cow. It was a double lung shot so no bones larger than ribs were hit. I'm now using 168gr. Barnes TSX and getting very good accuracy. I have complete faith in Barnes TSX bullets getting the job done.
I have seen the30 cal 150 sst take many animals. All died just fine but it is a thin jacket that blows up in the animal. In my opinion it is not an elk bullet and could blow up on the shoulder and lose your elk. Very similar to the sierra game king bullets on elk. Just to thin and fragile jacket. The 200 grain nosler accubond is a good quality hunting bullet with high bc that would get you to 900 yards better than the 150 sst. I think the 150 sst is better served for deer and antelope.
Predictions are difficult, especially when they involve the future
