Another aspect of all this, is how long will the ammo be commercially available? And where?
The .270 Win or 7 Rem Mag will be available for ever about anywhere in the world.
Look at what happened to some of the fashionable-fad-of-the-moment Winchester Short Magnums; Remington Ultra Magnum; Remington Short Action Ultra Magnum; Imperial Magnum; Lazzeroni Magnum; etc. etc.
Bottom line is that after the excitement of the moment and the impulsive buy of the 1,000 yard hunting rifle
unsure
, the ammo that gest produced is the ammo for which there are hundreds upon hundreds of thousands of rifles out there ... or a critical ethos that is vital part of a corporate identify such as Weatherby. As long as they exist, and they seem to be doing well, they will load for their calibers...
Edit:
Ha! C.W. Richter and I must have clicked send at about just the same time and aside from the notion that I have a few doubts about hunting at 950 yards, we are apparently passing the same concern re. ammo availability...
