Something I'm noticing with the 264 win mag load data I look at is that case fill is on the low end most of the time. Why is that?
Retumbo is THE powder for 264 wm.Noticed the same when I had mine. Lots of new powders out now that are slow burning which should do well in it and have better case fill. Mine liked Retumbo so never experimented much more after that. I just don't think there were enough super slow burning powders until recently.
