George, I'm sure that your results were excellent with your Blaser rifle.
Here's one of the problems with switch-barrel rifles: They don't switch fast enough. On a number of occasions I thought that we were out to hunt some sort of plainsgame species, only to be driving down the road to do so we'd spot a lion, or a herd of buffalo (or else a lone bull) and then we'd stop the rig as fast as we could, grab a rifle, then get out and make a stalk. And sometimes those stalks would turn into half-day marathons.
There wasn't time to switch barrels - just grab the 458 or the 416 and have at it. The 300 would then be carried by a tracker, just in case........
