For those who haven't shot various types of .17 hmr ammo I have a little bit of a report. I shoot 17 grain Hornady vmax, by far the best in my opinion. I have shot Winchester vmax, one of the bullets split in my savage and became jammed, haven't shot those since. I have also tried the CCI dynamite hollow points, wasn't as satisfied as the Hornady. Also have shot some 20 grain Hornady but don't remember enough to recall.
