Winchester .21 Sharp rimfire

[Anvil]

What can be better told of this new caliber?
Is it more economical than the .22 WMR!
Is it more accurate than the .22lr?
Is it something NAA should consider in development?
From what I've read so far it works in .22lr guns but not as accurate as firearms made just for it.
Sounds like the sales department talkling!
Personally, I think the rimfire catagory gambit has purdy much done it's course.
.22 Short
.22 Long
.22 LR
.22 WMR
17 HM2
17 HMR
5 MMRM
And now the .21 Sharp
I'll stick to my druthers and will stay with the 22 short. 22 lr and 22 mag.
However I am intriged with the HM2 if any members can give me more input.
