The HMR is based on the 22WMR case
and the mach2 is based on the LR case
and the mach2 is based on the LR case

The .22mag case has greater powder capacity than the LR case so is the HMR higher velocity and flatter shooting?

just to nitpick, the 17mach 2 is based on the 22stinger case, made by cci. the 17Aguila/pmc is based on the 22lr case, and can be fired through a 17mach 2 rifle, just fine, but may or may not be as accurate.
the mach 2 is about 2100 fps from the muzzle, maybe a tad faster. the hmr is about 2600 fps from the muzzle, also maybe a bit faster. the Aguila round is about 1900 fps from the muzzle, but does it with a 20 grain solid fmjbt bullet.
Also the hmr rounds cost about 3 times as much as the mach 2 , or Aguila rounds.
Fieldwise, the 17hmr has about a 60 yard max gain over the mach 2, legitimate 200 yd shots can be taken with the 17hmr, with only a 7 inch drop , from a 100 yds zero. the mach 2 can make a fine 150 yd shot, with about a 12 inch drop at 200 yds.
