Thanks for the GR8 info guys ,I am not one of those people who get all misty about muzzle velocity

bit like boxing featherweight vs heavy weight

speed and power are not always the same untill you NEED distance, then you sacrifice one for the other

or step your size up.
The 17hmr is a great fast flat traj but at 100mtrs IMHO the .22wmr has a better impact at that range. it is that age old speed V's impact.
I will stick with the .22wmr as I have that already and can't see where the advantage lies for me to go 17hmr as it would only be of benefit if I was to hunt game of small size at distances over 100mtrs. this is not likely as I have a 243 that takes care of anything over 100mtrs.
From what i can see and not personally tested .. is that under 100mtrs the .22wmr has a better punch then the 177hmr. over 100mtrs the faster veloicty of the 177hmr puts it out in front.
As for the .177 I was just going to go a cheap gamo $220 inc scope as it will not even accompany us on trips away, as I will, already have 4 riffles with us.
A bit of a play thing for home and a learning aid but when away on trips it's powder only and switch on .
