Never have used a .17 cal, shot a 17 hmr a couple times, but never took it out very far. I could see how that would be a fun caliber for ground squirrels, prairie dogs and similar.
I had a 204 for 1 winter and never cared for the way it put dogs down, maybe at the time it was a problem shooting cold weather on shoulders that fast, but would get splashes, spinners and runners. That is a reason I like the .224, still crank the speed up for flat trajectory and still have a punch. Probably the most devastating combo I ran in .224 was a .22-250ai with a 1:9 and running the 75 amax at 3350. Made a couple shots 600 yards range and it would tip them right over and the ballistics where very capable to go further.
For those of you running the 6mm I am a fan too, just .224 comes 1st if ever asked. I have had 2- 243 ai and a 6-284, never could get the 6-284 to shoot great so thats when I built another 243 ai.
The 1st one I ran berger 95 grain vlds and this was the 1st gun that I really got into long range with. Longest dog was 750 and longest shots made accurately were 1250 to 1275, low recoil, cheap components and very capable whether steel, dogs or deer.
Obviously when a dog presents itself, everything changes to put that dog down. Here is a link to a video of a coyote I shot with a 338 norma while waiting for a deer to come out for my dad.
Love the discussion, sharing and talking about the small game hunting.
