My only issue with 17 is your getting such low bullet weight that you likely will struggle penetration wise. With 22 Magnum 12” plus is doable even with hollow point loads if there proper loads. I think gold dots made something like 13” and the critical defense 12” both exhibiting something like .30 or better diameter. If expansion is unimportant stuff like maxi mags will do 16”. I like the little 351 as it has no recoil or weight it weighs iirc 11oz and 7 shot..22 Mag has got a bit more spice. I wonder about the .17HRM.
