It just figures that they would bring the whelen back after I just got the 357 mag. Well, not reason to ream the mag to a max I guess.
I always go back to expansion ratios before I get too upset about barrel length. And I like to think in general terms, not absolutes - we never no these data absolutely. So, the Whelen is a necked up 06 case, compared to the 25-06 which is necked down. The bore area and volume is roughly double that of the 26-06 sibling and 35% more than the parent 30 cal. I dont believe the whelen is starving for every extra inch of barrel as much of some other chamberings that are closer to being "overbore" if we can use that illusive term. Then, for the general guidelines of FPS per extra inch of barrel, I would swing to the lower end of the range rather than the uper end of the range. I think one of my more concerns with the Whelen is the aggresiveness (lack of) of the reloading data, especially compared to the 338-06. Granted, I have not looked exhaustively at a lot of whelen data. I would get one of the USA 1 Load Loadbooks for it eventually.
Now, I have almost resolved that my whelen will be a rebarreled LH Savage project gun. We will see how I flip this over and over the next year or so.
