Blackheart: In the state where I live (Montana) it IS legal to shoot Big Game with the 17 HMR and the various 22 Magnums as well - there are NO caliber restrictions here.
And yes I have heard of several folks shooting Deer with various rimfires INCLUDING the 17 HMR.
I have not witnessed these situations so I have no first hand observations to relay.
I do not recommend this Deer Hunting with rimfires - nor will I ever be trying it myself.
I will repeat though - in case you did not understand me - anyone who thinks the 17 HMR is less lethal than the 22 Magnums simply does NOT have enough trigger time with the 17 HMR!
ESPECIALLY on the size game for which the rimfires were designed for and intended to Hunt with.
You conveniently left out the results of YOUR Deer shooting experiences with the 17 HMR - could you correct that glaring ommission for us?
Or not.
And this - just out of curiousity which state are you harvesting your Deer with the rimfires in?
Hold into the wind
