For clarification I am ok with 1 powder for the small rifle cartridges and a second one for the medium. It doesn't have to be 1 for all of them.


Looking for suggestions on 1 powder to keep in supply for each "class" of firearm I currently have. I recognize it may be a dream, just wonder if someone has done a similar thought experiment before.

Criteria:
Temp Stable (North Dakota)
Cost
Decent numbers (ES/SD/Group Size)

Small Rifle:
.223 - 75-77gr
300 Blackout - Subs

Medium Rifle:
.25 Creedmoor - 134gr
.284 Win - 162-175gr
.270 Win - 130gr
 
CFE223 was not temp stable at all in my experience. No research but variations apparent day to day. Later saw similar complaints online. VV N133 is my suggestion or if you want a ball powder to meter SB Match. I have used both.

I always used Winchester 748 or H4198. We can get cfe223 around here right now. The others not so much. Can't even get Varget without ordering it with all the charges. I've used it with 77grn. bullets.
 
Off the top of my head:
Varget and H4350 are two that would work for all of those. Not saying they will produce highest velocity, but they’re both at least a good option and temp stable. Depending on bullet weights, Bechmark on the slightly faster end and H4831sc on the slower side of H4350 might be better.
 
If I was starting right now with new calibers and an empty powder shelf I would likely go 100% Vihtavouri powders.


I'd do some parametric powder searches using Gordon's Reloading tool and look for powders that gave near max velocity with 95 to 104% case fill.

Ill look into the suggestions, thanks all
