If I had to pick just one it would definitely be the .17HMR. Ammo may be a little higher, but the accuracy is amazing. I chronoed the ammo out of my Savage 93 and the CCI avg. was 2762fps. with the 17gr. V-max. Fed. and Hornady both were above advertised velocity. Terminal ballistics at 50yds. were rather impressive with V-max and 20gr. hollow points. I think you made the right choice though, one of each.
