There listed charge on their website seems to be about the same as H-110
too?
I also saw no mention of Magnum primer need either .
But I used Winchester as it seems like a lot of powder to ignite.
Anyone else using it ?
The big bang that 2400 has is noticeably absence with 300-MP and I am using 5 grains more !
