This is the best .17 HMR ammo I have used to date. I have tried the Remington and the Hornady but the CCI works best for me. This ammo produces excellent results. Lots of energy. I would compare it to .22 magnum just by the results it produces. I won't go into details but I had tremendous results using this ammo this past weekend.
At the paper target range I didn't find any difference using 17 grain vs. 20 grain rounds at 100 yards as far as sighting in my rifle.
I believe the 20 grain produced more results in the field than the 17 grain did. 17 grain rounds do the job no doubt, but I found the 20 grain rounds to produce, how can I classify it...more extreme results.
Several of my hunting partners and I have used about every kind of .17 HMR bullet you can find. This one,(20-gr. game point), has never failed to produce the results we were looking for. What you lose in FPS, you gain in energy and expansion at impact. Varmits as big as coyotes have been taken with this particular round!
