Slow Burning, Temperature Stable

[Good]

Hi all, I'm hoping you all can tell me what powder in the slow burning category is going to be the most temp stable. I'm not necessarily interested in the most speed, just a powder that is stable and consistent from winter to summer and doesn't need tuning.

Powders such as:

Reloader 22, and 25
H-1000
US 869
Ramshot Magnum
IMR 7828
Retumbo
H-870

Thanks for your help.

H-1000, Ramshot Magnum, Retumbo are all worth working with.

hogdon extreme powders are supposed to be very temp insensitive and very consistent lot to lot

So is it generally believed that the h-1000 and Retumbo are the most temperature insensitive of these listed? Of these, those are the only two in the Extreme line.

None of the others match up? Which of them have less spread in temperature changes? I want to start working with that powder, if the gun doesn't like it I'll try the next bet for this particular application. It's for 338 RUM and 300g Bergers, btw.

You can't go wrong with h-1000 in your situation. A good friend of mine uses this with the 300grners from summer to late whitetail season with great sucess.

There are many more extreme powders that should work in the 338 RUM with 300 grain bullets
like the H 50 BMG and the H 869.

869 is not an extreme powder
