7828ssc or H1000 300win mag

[LVJ76]

How temp sensitive is IMR 7828? TIA

 

[LVJ76]

I only have 185 and 190gr VLDs for my 300wm for now, but my best powder for these bullets is 7828 by far !

I've tried h1000 but 7828 gets me another 100 to 120 fps without pressure signs. And better precision.

Same deal with 7 rem mag.

What is your load and with what bullet on the 7mm Rem Mag if you dont mind me asking.

Thanks in advance
