Hi Randy! Long time no chat!
I’ve got some background with both calibers in question and I’ve found that I too lean toward the 22mag. Biggest reason? Versatility. You can shoot 30, 40, 45, and 50gr bullets so there’s a little more there for dialing in what your rifle likes. I have one that shoots 30gr, one that likes 40gr, and one that likes 50gr. My favorite is the 30gr shooter… A Henry lever with a 24″ octagon barrel. The gun slices 70-100 shots like none other I’ve ever owned. If the majority of your shots are going to be under 70yds, it would be gold! I have a Marlin bull barrel 17HMR and honestly, what throws me is slope.
I shoot 30 to 50 pests/varmints on my property annually, without hunting. Just right place, right time. Shotguns take care of 50% but the rimfires split duties on the rest. All depends on which one I keep close any given day. But uphill, downhill, or flat, the Henry with 30gr just never seems to miss. Last May, after stacking up 8 – 1 shot kills in a row between 42 and 73yds, I finally missed the kill zone on a running shot. Wounded the critter enough that shot #2 finished it. 47 & 53yd shots. I’ve aimed at the head of a cottontail and pierced the ears with the 17HMR, but hit ’em dead on with the 22mag, same shot opportunity. Slope appears to be a factor for me, so I tend to stick with what works most consistently.
I save the heavier grain rounds for specialty critters like coons, coyotes, and beavers. A 17HMR will get the job done if you hit them, but for me, I just do better with the 22mag.
Lastly, if you find yourself looking for a new 22LR and aren’t afraid to spend a little, I have a Ruger M77/22 in 22LR that shoots the wings off flies! I retired my old Remington 582 a few years ago and I chose this as its replacement. I also have Henry Golden/Silver Boys and they’ve been fun on paper, as well as out the window. For the closer window shots, I’ll even run shorts through the Golden Boy successfully. 2 cottontails fell 2 weeks apart to short range 22 shorts, iron sights.
It’s not necessary to own so many options, and if I were to thin the herd, I’d keep the Henry 22mag and the Ruger M77/22. I’d be willing to let the 17HMR go, even though it’s had some glory moments too. It’s just less consistent for me.
