Default IMR 4350 Alternative

All my guns love IMR 4350 30-06, 7-08, 243, 348 But noticed issues when temps get very cold. Is there an extreme powder like 4451 Has anyone tried this powder with good success? I have heard Vihtavuori’s N150 or N-550 is less sensitive to temps, maybe this would be a good option or Alliant Reloder 16? H4350 didn't have great results. With access and cost, I wanted to be more selective instead just buying a 1lb of each for $30 and giving all options a try, those days are gone. Any feedback would be appreciated. Thx

What bullet weight were you using with H4350 which didn’t go well? And what does “not going well” entail?

For 30-06, 4064 is the easy button. Although H4350 tends to be pretty simple itself.

h414 and winchester 760 are both fairly close on the powder burn speed scale charts

I use 4451 and it has been an excellent powder. I have found it to be as temp stable as the Hodgdon extreams and is a great replacement for IMR 4350.
