Less than ideal
First two were fine, but velocity was 150fps less than expected.
Shot three barely made it out of the case mouth
The primer fired but the powder "melted" rather than burned, and turned into a turd of powder.
I'm hoping it was merely a glitch so we're trying some hotter ones to get the velocity up and see if they work.
He bought five bottles of W748 so it'd be bloody nice to get it to work.
It might be that magnum primers would light it up better, but primer choices nowadays are extremely limited.
I'm not liking the powder though, it barely half fills the case. I don't think it's possible to double-charge it without some overflow, but there might be so little overflow as to not be noticed. I'll have to check the case capacity next time.
It might be that we need to use a filler to keep the powder down on the primer, but that would be annoying.
