[quote=RipSnort]For those that have used both of these rimfire cartridges shot out of rifles on game/varmints, which do you think has the edge in killing power?
Under 5 lbs., I prefer the .17 HMR.
Over 5 lbs., I prefer the .22 Mag.
I shoot called 'cats at close range, sometimes as little as 10', with a Remington 597 in .22 Mag. I don't know if I'd do the same with the .17 HMR.
