Based on the capacity it should be magnum speeds easily.

I think the .250 GNR is about the same capacity as the .255 Banshee, just a more squat and resilient case to form. H110 is my favorite powder for jacketed. Faster powders do great for cast bullets a little slower.

I need to cast some of those Mika 60 gr. HP.
