I shot and killed 3 last year with a 17 HMR, bullets were the 20 grain gamepoints. One ran 50 yards and died, the other two did the yipping death spin and didn't go anywhere.
Now before someone gets their panties in a wad, my main calling gun is a 17 Remington. I just wanted to see for myself how the HMR would do, and it was 'adequate'. Centerfires are obviously more effective.
A 5mm has quite abit more juice than an HMR and would kill them dead out to 125 with good shot placement. JMO
