None of those are really “fast” powders. I’ve never seen load data for it before but that is pretty cool stuff. It’ll be interesting when things all get sorted out. It’s a truly neat cartridge. I’d love to have that capability in a Kimber Montana 84L sized rifle.

I have a Classic M70 264 and a new made 264 and both are pretty easy to situate most bullets to get into the lands and still be within the mag. The chambers they cut were made for old 2 diameter bullets so normal bullets engage the lands under 3.3” most of time. By normal I mean 127 LRX, 140 ABs...
