Ramshot Magnum/Grand

[FLHunter87]

Has anyone used both of these powders? The description looks pretty similar. I have 1 pound of Magnum I have had sealed for a long time and haven’t seen Magnum available for years and I’m finally thinking about using it. I see grand is readily available and wondering if it is pretty similar or different. Trying to decide on using magnum or 565 with 150g bullets for a 6.5 PRC. Or even just used one or the other?

They are literally one spot apart on the burn charts. Grand is marketed as temp stable. I have used both very sparingly (pressure ladders and initial test groups) in a couple rifles, but didn’t see what I was looking for so I moved on to other powders. I haven’t given up on them, they just didn’t work for me in those situations.
