I bought a Savage 17HMR not too long ago and wouldn't trade it for the world. I also have a Rugar 10/22! Both are very fun to shoot and both have perks and both have their downers.
17HMR Savage 93R
Bolt action( little more accuracy) Heavy(free-floating barrel)
Can consistanly make 1/2 groupings @100yrds
(on a good day)
ballistic tip (go with Hornady 17gr 2550fps) $13.99 a box of 50
Don't be affraid to put a higher power scope on, its nice making 150+yrd shots and dropping ground hogs(I have a 4-16X50mm pwr scope) I rarely shoot higher the 8-9 power though.
This is a one shot kill gun, the volocity is extremly fast and the tip is very deadly. (I Kill Turkeys consistanly at 100+ yrds with only one shot through the shoulder.)
The damage to brutal(dont shoot too many squirrels,Very blood

)
Ruger 10/22
Heavy barrel, semi-auto, great shooter, a lot of fun, and cheap to shoot!
Lotsa perks
ammo is vary cheap, readily available, easy to find.
semi-auto makes is nice to shoot with a 20+ rnd clip.
volocity is slower but heavier gr.
BUT REMEMBER
SPEED KILLS!!!!
Kenetic energy= mass x volocity(squared)/2
my, opinion(not worth too much) go with the 17HMR! you wont regret it!
