Hi Ian. I suppose it begs the question , Why hasn't a manufacturer made the 22 BR a commercial calibre if they are superior.
Personally I don't think it would make much of a dint in the 22.250 sales
Look at its bigger brother , the 6 BR , Despite producing factory ammunition and some factory rifles. ....
It only has a tiny following compared to the vastly more popular 243 . Despite the extra powder, extra recoil and promise of inherent accuracy . The 6 Br hasn't prised most 243 shooters away from their trusty rifles.. Why .. because you don't shoot groups on Deer or coyotes , therefore measuring group sizes in 0.1 's has very little relevance to hunters.
Same principal goes for Fox shooters and vermin control, A standard 22.250 factory rifle can produce 0.5 MOA.groups at 400 yrds. Therefore easily sufficient accuracy for any vermin and very little would be gained for the extra cost and faffing with brass.
As far as recoil - I have just plugged some rough figures in to a recoil calculator
The 22.250 produces 6.1 ft lbs of recoil ( 75 grn Amax @ 3300 fps)
The 22 BR produces 5.7 ft lbs of recoil ( 75 grn Amax @ 3300 fps
There is actually less in terms of recoil between a 223 and a 222 ....E.G Sweet FA
22 BR is undoubtedly superb performer - but that doesn't make the 22.250 inferior just because it uses about 3 to 4 grns more per shot... Otherwise the same argument could be used for the 22 PPC against the 22 BR.
