I bought a Bmag 17 wsm when they first came out. It’s a 2 moa shooter which is fine for what I use it for. It’s what I use when calling coyotes in populated areas, It kills them quick out to 150 yards and is much quieter than my centerfires.
I have used both on ontario ground hogs. Coons. Possums. Crows. Starlings. Grackles. Jackrabbits. Coyote. Ive taken fox with the 22mag but not 17hmr. In each case involving 4 legs the 22mag was a stand out winner. For birds the 17hmr was more violent.
A 30gr vmax from my 22mag did not expand at 225 yards after going thru a front shoulder of a large jack rabbit. It flattened it however. The first shot blew his lower jaw off and he was flipping in the field. Coons take the 17hmr to the chest and keep running whereas the 22mag drops them in the tracks or within 3' for shooting coyotes on frozen creeks i prefer a head shot and both work well enough. Ive had the 17hmr bounce off a coyotes head and all i got was fur shot head on facing me. The 22mag generally always exits the head. Broadside shots i can generally exit a coyotes chest with the 22mag. 40 to 50gr bullets where as the 17hmr i never got an exit and always had to follow up the dog and lost enough to sell the hmr. Ive never lost one with the 22mag
Hitting shoulders of a coyote the 22mag will break thru and into the chest cavity. Even the 30gr vmax under 75 yards. My buddy shot 3 coyotes with his hmr. 2 were shoulder shots that did not break the bone or reach vitals. One at 20 yards the other at 60 to 70 yards. Both were shot with my 2506 as they were leaving the county at full speed. His third was a neck shot and it ran about 300 yards. I couldnt take a safe shot to back him up.
I use a 17 mach2 and love it for small edible game and have shot a coyote with it right behind the ear and it was used to shoot a 65lbs beaver and it killed it outright. That said the 22mag is my choice of the magnum rimfires.
The 22mag has a very useful range of bullet weights and styles and has stayed the test of time. The hmr isnt going anywhere though
It comes down to what you want. Destroy small animals like rats and wester ground squirrels and birds id go hmr. If shooting anything bigger like a rabbit and upwards the 22mag is my choice
Ditto on that...I had both, prefer the 22WMR. The 17HMR is fun and accurate, but would be best suited to prairie dogs / gophers. I don't have those near me, so the 22WMR won
22WMR - closer shots, larger varmints
17HMR - further shots, smaller varmints
17HMR lacks power for foxes and coyotes.
Both of these calibers raise an issue I have. While the 22wmr is better than the 17hmr. They both seem to miss the mark... to big for small game. Like rabbits and partridge and to small to be really effective for predators beyond 100yrds.
Seems to me for small game a .22lr rimfire and then predators a Centerfire world work out better than either the WMR or the HMR.
If I had to choose one it would be the .22WMR for around the farm kinda use.
