Okay, there's a nice discussion going over in the Buffalo Bore thread and I didn't want to hijack it. It's pretty common knowledge that these powders are the same powder, produced in the same plant. I learned yesterday that one lot to lot of burn rate variation is sent to Winchester, the other to Hodgdon, although now Hodgdon owns them both. My question is that I've been looking through cast data for .308 Win and .30-06 and have found a few loads that use H110 in small doses. This is NOT a powder to use for reduced loads, at least in pistols, so what gives with the rifle? I've heard this is a prime candidate for Secondary Explosion Effect and I'm awful leery of using H110 in a rifle case. Any thoughts?
