Have never seen one, in fact I doubt there is even one in the UK what with our stupid restrictive rules

, however I do wonder with such a case capacity why the short barrels?
The more I look at new production rifles the more I see short barrels. Am I missing something as it matters not what calibre of cartridge the rifle is chambered for they have darned short barrels. I rifles in 270 Win and 26-06 with 20" barrels what in the world?
Why bother with such cartridges then as you just strangling it's potential. You might as well have a smaller less powerful cartridge in the first place and save powder.
I would expect a case burning some 80 grains of powder to do it's best work with barrels of at least 23" and more.
Now if you really want short barrels why not get something like the old .375 Whelen. I very much doubt suitably loaded you would lose much velocity in a 20" barrel and not waste all that power and powder.
I wonder if folks would be so eager to waste powder so when it cost near $70 US per 1lb tub?
Personally my thoughts are once again the manufacturers are pushing these short barrels to increase their profit margins. Short barrels cost less to make, less material and less time to cut, hammer or swage rifling into the bore. Less time equals more profit especially if they can con the buyer into thinking it's a good idea.
Remember how they sold impressed chequering as the best thing? Folks fell for it too
