I have a short barrel 308 that loves the 311440. Seat them out to just touch the lands, 5744 powder, and she shoots really well. I don't have my load notes, so I don't remember the charge. Haven't got to pop bambi with it, but it vaporizes water bottles and the like. The flat pointed bullet just looks like it wants to thump something, and the 308 is turning out to be a great cast bullet caliber.
