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?

I tried 165, 168 and 180 Never got a consistent grouping with H4350

A good powder also for thise cartridges is,IMR4064

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.
