Like all rim fires they are particular to one brand or gr ammo, I have the Savage 17-93BTV, when first purchased I used 17gr it would shoot about 1.75 to 2.25 at 100 yards I purchased some 20 gr and groups improved down to 1.50 to 1.70, I returned to Savage and upon return suggested I use Hornady 20gr it now shoots .700-1.00 average, I do not know what other points savage tweaked but it was improved.
It "is" very wind sensitive anything over 10mph it becomes a matter of how you can judge wind, all in all I do not consider it a great target caliber and I have never hunted with it, normally I use it at the range to give my Savage model 12 223 BTVS a break during shooting sessions,the model 12 223 will shoot under .500 with my reloads.
I have mixed feeling on the 17hmr, personally I think the ammo is over priced I pay normally $10.99-12.99 for 50, I think for hunting prairie dogs or groundhogs in a non-windy area would be fun but don' expect it to be the miracle caliber so many want it to be plus it may be limited to 150 yards for consistent clean kills.It fills a niche between the 22 LR and 223 the noise level is low which would help in more congested areas. IMO in time it will drop in popularity as the 22 mag has.
