For years I hunted mostly crows and grouse with a 12 gauge shotgun, and often carried my Ruger .22 cal LR MK 2. pistol. I grew tired of the crows that refused to come into my shotgun's range, and my pistol had a sizeable drop at 100 yards that caused me to loose shots as well because if shooting at an up angle the trajectory drop is not as profound as level to level where the bullet really dropped, and I got tired of having to calculate angles, I felt like it was a math class.
When the .17 first came out I wanted one because, as 44 Man noted, you don't have to worry about hitting someone or something due to declining residual effects at increasing distance, and the official charts from the ammo makers show that the .17 HMR has a flatter trajectory over the .22 Magnum. Now I have a cartridge that will hit where I aim at 100 yards, and will hit a crow with a reasonable drop allowance at 200 yards and not kill somebody's horse at a mile.
Where I hunt there are farms nearby. I would like to use my .357 magnum revolver over a .17 HMR for hitting power, the drop is about 4"-5" at 100 yards, but that 125 grain slug could carry aways too! :shock:
With the .17 HMR Ruger singe action I could use it as an option for when I do use my shotgun in the future. However, this year I plan to hunt mostly with one of my 2 recently purchased .17 HMR rifles to see how well they do. I know the crows are waiting, and they will fly away if I keep missing them as they are intelligent birds, and the .22 magnum will be difficult to hit them at 200 yards.
I think that the .22 Magnum versus .17 HMR is going to be a test of time issue. We will have to wait 5-10 years to be sure.
