With modern powders it is no trick to get 2250 fps with 450 grain bullets or 2100 with 500 grain bullets without excessive pressures or excessive powder compression. Personally, I think there is no need for the Lott.
If you could buy a .22 short-only rifle or a .22 in which you could shoot both long rifles as well as the 22 short you would choose to buy the former and claim there is no need for the latter? It seems that claiming the opposite is the more rational. Just because better powders now make the 458 adequate to good doesn't make the Lott which can be a "458 Win" at lower pressures or a Lott (more) at 200-250 fps faster and shoot the Win version to boot less desirable. Plus rifles are of the same action length obviously and Weight.
The reason the Lott came into being was disappointment in the Win's performance which has now been improved. That improvement doesn't make the Lott redundant; it also makes it better.
I'll still take a .22 that will shoot the long rifle too and substitute the short if conditions warrant.
