Seems like Alliant has a new magnum rifle powder out called Pro 4000 MR. I assume its newer but maybe some of you have used it.
It seems like it may be a small ball spherical not unlike and similar to Ramshot Magnum and Accurate Magpro. Does anyone have any experience with it in 300 Win Mag or 7 mm Mag? Is it gonna be temperature sensitive? Seems like I read only the longer stick extruded powders are better at being insensitive in temperature changes.
What do you think if you have tried it?
