Again yes Bubba is capable of overloading anything. Do you really think Speer doesn't know what they are doing and are exceeding normal chamber pressures? That possibility would be next to zero in my opinion. They list Power Pro 2000 MR as reaching 2709 fps, CFE 223 reaching 2664 fps and Power Pro Varmint getting 2617 fps all from an unspecified barrel length which I assume is going to be 26" since that seems normal these days.
No one doubt's a new powder like RL 26 in the 270 or 280 Rem for example reaching a speeds lot higher safely than other powders available previously. It looks like they found a couple of great new powders that work very well in the Whelen and I bet similar sized rounds.
