For my uses the data should be provided with a 22" barrel or shorter. I wonder how the Weatherby would chrono out of these short tubes? I also am very fit and 60 years old and for my style of hunting weight is of real concern. I now use a .270 win with a 19 " barrel for sheep and elk. With R26 and 150 Partitions it chrono'd over 2900 fps. The only piece of equipment that isn't lightweight is my German binoculars. Barrel length is an eliminator for me.
