You put oddball cartridges up there but didn't list the most popular ones? No 22-250, and you listed 22 rimfire but didn't bother to list 22 mag, the 17HMR or the 17HM2

For me I would pick the 22-250 for a pure varmint round, and it is probably the most popular where I live.

Lots of people use the 30-06, 25-06, 6mm and 270 as well.
