I have both i personally find myself shooting the 17 more then the 22. Cant wait to use it on a fox or a rabit flat shooting have pushed it out to 200. Only down side is wind can be a killer. Why dont you just get both lol

A few years ago I did some ballistics tests with the 17HMR, shooting 17 grain vmax into ballistics gel at 100 and 200 meters. First thing is people need to loose the myth that 17s are hell in the wind. If you think the wind adversely effects the 17s trajectory then consider that compared to other rimfires, ie, the 22LR and 22WMR, the 17 is far more resistant to wind drift.
At 100 meters the 17 vmax is explosive to the extreme in the ballistics gel. Relative to bullet diameter, a large 30cm wound channel with great fragmentation. There was a lot of damage. At 200 meters, the cartridge maintains great accuracy, but on impact, the projectiles would no longer fragment and because of this the wound channel was much narrower and longer. At 200 meters The recovered projectiles maintained 100% mass minus the poly tip which would separate and beak in two pieces. At 100 meters there was nothing but fragments to recover.
As far as killing power, and this is from field experience shooting hundreds of rabbits and dozens of foxes, the 17HMR has it in spades over the 22LR. At distances of 70 meters to 150 meters, the 17s performance is way above the 22LR. At 200 meters the 17 has the accuracy to take head shots, but expect crawlers if you take a chest shot as the little bullets no longer have the energy to expand and fragment.

The first time I saw the 17HMR I ordered a ruger lever rifle and had a ball with it.We had a problem with ducks flying in the sullage dam then landing in the fresh water dam at the dairy farm so the farmer liked me getting the ducks I learned that if I placed the shot just where the neck starts to fatten out on the body it dropped them on the spot and did not damage the breast meat.All the internal organs would be mush.They would waddle along in a line and once I got 3 working from the back before they flew off.My best was 150m and it did the same damage
