H1000 Substitute with 208 ELD-M in 300 WM

[Johndeere1]

Been using H1000 in 300 win mag and running low but H1000 is hard to come by...
I've read about IMR 7828 SSC being very good with heavies. I'm in South LA ( That would be Louisiana...Not the corrupt Liberal Left Lost Angeles) and have a hot summer and cool winter. Wandering if the 7828 would be too temp sensitive down here.
Long Range target accuracy and consistency are most important.
Thank ahead!

I would suggest IMR7977 as a suitable replacement for H1000. It is near in burn speed and has the Enduron temp stability you're looking for.
Also, most importantly, it is available at Powder Valley today.

I had good luck with h4831 with 212 eldx In 300wm. 2930fps @73.8gn

Ok!
I've read about both IMR7977 and H4831 being good with 200+.
I will try to pick up whichever is available and work up.
Never had to shop an alternative, only read about them. Only had one LR load and stayed with it for a long time.
Thank You for the help!!
