22 LR or 22 MAG does the same thing with better results.
The 22 lr does NOT do the same thing as the 17HMR - try this , zero yor 22 lr at 50yds and shoot a group and then shoot a group at 100yds with the same scope settings. Do the same with your 17 HMR.
Try some 100 + accuracy testing with your 22lr vs the 17HMR. The 22 Mag argument makes more sense.
