From Keith;
" For the record I own two .17 HMRs (one Contender pistol and a Savage rifle) and two .22 Mags (Contender pistol and 77/22 rifle). I see them as fish from different seas. .17 HMR is great for long distances and small critters. .22mag is better for shorter distance and slightly larger game. The constant mine is better than yours is silly and meaningless. It is highly unlikely that one will out compete the other. I don't shoot yotes with the .17 HMR (or the .22 mag either).
I reject that wind "over a slight breeze" ruins groups out of .17 HMR. I know it doesn't. I shoot one. I also reject people quoting other peoples aleged experience, or blanket statements about what is happening nationally because of the guns at one shop.
Shoot a few bricks of ammo out of a gun and then tell me about it. I will be more interested."
I tend to agree with Keith. The .22 mag and the .17HMR are two different critters. Move up a few bumps, and it is more like the 30/30 vs .223. One slower, but heavier, the other faster and lighter..
I heard all those phrases, claiming the .17 HMR is very subject to wind drift. I have had 2 different .17s and several different .22 mags, and see no difference so far a wind allowance is concerned.
Let's reason it out..yes, the17 is lighter, but due to it's smaller diameter, it presents far less surface to the wind.
Yes .22 mags can vary greatly, so far as accuracy is concerned. Originally I had a couple Savage/Anschutz in .22 mags. (actually all Anschutz)
I have a terrible habit of passing on my guns early...after all, i can't see my loved ones enjoy them after I'm dead, so
one went to my son, the other to a grandson when he returned from Iraq.
Son, I wished I had another .22 mag, so I tried a few at LGS shops..none came near..I even bought a Marlin 783. No luck! So I swapped it away..
I gave up for some time, but then a couple years back, I happened to stop by my friend Mark's, gun shop. There sitting in the rack was a new, plain Jane Savage 93..with black fiber stock..just a base model.. which he sold to me for $216.
Took it home and tried it ! ..Ah, my Anschutz was back..
Below, see a fox I still hunted, ending up by kissing my hand between thumb and forefinger..rat/mouse sound to draw him in..
About 100 yards..broadside in the boiler room...dropped right there, like a sack of sand..
