When I was loading for it, I was in love with high SD bullets, hence the 120, 117 and 115. Nosler had not yet re-introduced the 115 Partition, so I didn't try it. And I'm pretty sure I need not fear bullet blow up with an X bullet. But I'll get back to it one of these days and try a few other powders with the 100, 115 and 120 Partition, and maybe the 110 AB.
