The 17 WSM is the better long-range and windy-day cartridge: it pushes a 20 grain bullet at about 3,000 fps to the 17 HMR’s 2,350, and in our Savage B Series shootout it kept hitting at 250 and 450 meters where the HMR did not. The 17 HMR is cheaper, easier to find, chambered in far more rifles and shot tighter groups at 100 meters. Inside about 150 to 200 yards, buy the HMR; past that, or in real wind, buy the WSM.

The Cartridges Explained
17 HMR
The 17 Hornady Magnum Rimfire was developed in 2002 by necking the .22 Winchester Magnum Rimfire down to .17 caliber. It was an overnight success despite costing more than other rimfires. It shoots flat and accurately, and the light bullets are very effective on prairie dogs, squirrels and other small varmints. The most common loads use 17 grain bullets at about 2,550 fps and 20 grain bullets at about 2,350 fps, per factory ratings. Our earlier 17 HMR vs 22 LR shootout made the HMR the clear winner over .22 LR for distance.
17 WSM
The 17 Winchester Super Magnum, introduced in 2012, is a muscle car of a rimfire. Its case comes from a .27 caliber nail gun blank, with brass about 50 percent thicker than the HMR’s. That lets it run about 7,000 psi more pressure. Factory loads push a 20 grain bullet at about 3,000 fps or a 25 grain bullet at about 2,600 fps. The bullets are basically the same as the HMR’s, just faster or heavier.
The tradeoff is the primer. The WSM uses a very hard primer that needs a heavy firing pin strike, so rifles in 17 WSM have stronger mainsprings and bolts that take some getting used to.
The Test Rifles: Savage B Series
Our author, Clay Martin, tested two Savage B Series bolt-action rifles. The 17 WSM gun was a Savage B.Mag with a heavy barrel and a laminate stock. The laminate stock had a longer length of pull and a better comb than the synthetic B Series in 17 HMR. The B.Mag has a 22 inch barrel, an 8-round rotary magazine that ran flawlessly, and the Savage AccuTrigger.
Two complaints about the B.Mag. First, because of the way the bolt cams to cock the heavy firing pin spring, it is easy to short stroke until you get used to it. Second, it came with Weaver bases, which the author does not like. That is personal preference, and Picatinny bases are available aftermarket.

Range Test Results
The HMR wore a Steiner T5Xi and later a Vortex Razor Gen II 4.5-27. The WSM wore an older Vortex 4-16X because of its Weaver bases. Ammunition was American Eagle and CCI. The author used Applied Ballistics to bracket his wind calls and a large steel sighter target.
Accuracy at 100 Meters
The 17 WSM shot a 1 inch group at 100 meters, which is excellent for a rimfire. The 17 HMR shot a group about half that size. That set up the real question: does a less accurate rifle with better ballistics beat a very accurate rifle with weaker ballistics once the wind picks up?
Test 1: Tomatoes at 150 Meters
With wind over 11 mph, both cartridges hit tomatoes at 150 meters, but the WSM made it much easier. The HMR needed 0.3 mil of elevation while the WSM was still point of aim, point of impact, and the WSM needed only about two-thirds the windage. Point to WSM.
Test 2: Juice Cans at 250 Meters
At 250 meters with wind averaging 14 mph and gusting about 3 mph either way, the HMR scored no hits on 5.5 ounce juice cans despite confirming elevation on steel. The WSM cleared its own cans after a couple of sighter rounds, then cleared the HMR’s leftovers too. Point to WSM.
Test 3: 10 Inch Gong at 450 Meters
On another day with a steady 6 mph wind, the author moved to a 10 inch MGM hex gong at 450 meters, a little over 2 MOA. The WSM scored two hits at 3.5 mils of elevation, which is probably the ragged edge of its reach. The HMR needed 6.5 mils, its impacts were nearly invisible even through a 27X scope, and it scored no hits. Point to WSM.

Which Should You Buy?
Both cartridges are winners. It depends on what you need.
Buy the 17 HMR if you shoot mostly inside about 150 to 200 yards, want the cheapest .17 rimfire ammo, and want the widest choice of rifles, including semi-autos like the Savage A17. It is accurate and still a great varmint round.
Buy the 17 WSM if you hunt with a rimfire, shoot in the wind, or want to stretch a rimfire out to 250 meters and beyond. It brings a heavier bullet faster, and it filled a long-range rimfire training role out to at least 450 meters in our test. Savage also offers the WSM in its semi-auto A Series, as we covered in Savage adds 17 WSM to its A Series line.

17 HMR vs 22 WMR: Quick Answer
The 17 HMR is literally the .22 WMR necked down to .17 caliber, so the two share a case. The HMR trades bullet diameter for a light, fast bullet that shoots flat and works great on prairie dogs, squirrels and other small varmints.

17 HMR vs 17 WSM FAQ
Is 17 WSM better than 17 HMR?
For range and wind, yes. The WSM drives a 20 grain bullet about 650 fps faster than the HMR’s 20 grain load and stayed effective at 250 and 450 meters in our test where the HMR did not. The HMR is cheaper to shoot, more accurate in our test rifles at 100 meters, and has more rifle options.
Can you shoot 17 HMR in a 17 WSM rifle?
No. The cases are different, and you should only fire the cartridge marked on your barrel.
How far is 17 WSM effective?
Our author hit a 10 inch gong at 450 meters in a 6 mph wind, which he considered the ragged edge of its reach. For hunting, most shooters keep it much closer.
How far is 17 HMR effective?
The HMR hit well at 150 meters in 11 mph wind but scored no hits on small targets at 250 meters in 14 mph wind. For small game and varmints, most shooters keep it inside about 150 to 200 yards.
Is 17 WSM ammo more expensive than 17 HMR?
In our 2017 test, 17 WSM ran about 24 cents per round and 17 HMR about 18 cents per round, both 2017 prices. The HMR is also easier to find.
Why is the 17 WSM easy to short stroke?
The 17 WSM uses a very hard primer that needs a heavy firing pin strike. Savage’s B.Mag bolt cams the stronger spring in a way that makes it easy to short stroke until you get used to running the bolt firmly.

So he used the savage b mag chambered in .17 WSM to shoot both the .17 wsm and .17 hmr ammunition? The B-Mag can shoot both rounds safely?
Never mind just watched the video the article did not steer he was using another rifle.
The gov’t cannot make laws and then ignore their own rules.
Your comment is out of context and you sound like a mongoloid talking to himself.
I just got a used Savage A17 with thumbhole stock from my LGS. The idea is to use it when we visit family in Montana and go “dawg” hunting. So much fun the last time and I was using a 10/22. I just need a good scope for 100 yds..any thoughts on that..?
In my mind, the .17 HMR vs the .17 WSM has never been a match-up worth debating. Choosing between .17 HMR vs a .22 Mag would be a lively debate – probably with no clear winner. However, I have always wondered why someone would choose a .17WSM and not just go ahead and step up to a .223 Rem. What does a rim fire really give you in that package? What would a .17WSM give you that a .223 could not? It just never made sense to me.
Not everyone reloads. Why set up a complete reloading system for just another 200 f.p.s.velocity for small varmints?
You can reload the .223 but you don’t have to. You obviously can’t reload the .17WSM. If you are deciding between the .223 and the .17 WSM, I still say go with the .223 – even if you don’t reload now it still gives you the ability to reload in the future if you ever decide you want to and until then you can buy off the shelf ammo that is easier to get and has more load options than what you will find in the .17 WSM.
To me the debate between the .17HMR and the .17WSM makes about as much sense as debating the .17HRM vs the .223 Remington. The .17WSM tried to carve out a space that is ballistically between the two and landed closer to the .223 than it did the .17HMR. As such I feel like you should compare those two cartridges and when you do I think the .223 wins by any objective measure except for a tiny advantage to the flatness of the trajectory for ranges under about 150 yards.
I really want to love the .17WSM but I just don’t see the point.
Well DUH. I can’t believe you felt the need to say a .223 will out perform the .17 WSM. You kind of touched on my reason for me choosing the WSM over a centerfire – i don’t want to reload and purchasing quality ammo for a 223 is cost prohibited. I like to shoot prairie dogs and 500 rounds of 223 at 25 – 30.00 for 20 gets expensive quick. How about purchasing the reloading gear to “mass produce” that much 223 in a reasonable time frame? Slap down another grand or so? I can get 50 rounds of WSM for 10 bucks on line. It will reach out to 250 ish and shoots 1/2 moa with a gun I have 500.00 into. The WSM didn’t come looking for me, I was looking for it.
Some states have rimfire laws for hunting. So for a rimfire this is your best bet ballistically
Great point Brad, just got my B-mag topped it with a cheap scope 350$total and shoot a2.5″group@300this morning off sticks! and haven’t opened my second box of shells, all the horror storys about there inherent lack of accuracy, just don’t see it
If you want to get RICH, Create a 22 Caliber or 22 Magnum that will shoot a flat Trajectory like the 17 caliber!
neat article, Clay.
I’ve had my eye on a nice long barrel accurate 22 mag and scope. Around here in Florida, for our distances and vermin, it would suffice. If I lived out there with some range, your highlight of that 17 wsm would make me say, hey, give me one of those for a time.
Neither of my 17’s are for sale. Nuff said!
30mm 16X and 27X Hubbles on rimfires? ROTFLMAO!!
20 gr pills at 3000 fps? ROTFLMAO!!
17 cal. MAGNUMS?? ROTFLMAO!!
Better hope the hearing protection act passes in congress because this 27 WSM thingy is putting out some decibels which coupled with two plus lbs of optics certainly turns these rifles into one more useless addition to the concrete bench crowd.
Give me a 5-6 lb 22 LR or 22 WMR and you can keep your 17 whoopie doopies.
Intelligent people never left the 22 WMR. Half intelligent people are finally tiring of the 17 HMR and returning to the 22 WMR.
OK Fudd
I have an Anschutz Model 1717 (Bolt-action repeater) chambered for .17HMR that I have used for prairie dog hunting. That tiny 17 grain bullet is surprising effective on prairie dogs at 100 yards. The cartridge is very accurate, inexpensive, relatively quiet and has very low recoil so it’s easy to see the bullet impact through the riflescope. I’ve found the .17HMR to be a great squirrel round also, as it’s more accurate and has much better terminal ballistics than any .22LR round. You can hit the squirrel just about anywhere with the .17 and you’re guaranteed an instant one shot kill. The above test results of the .17 Win Super Mag are impressive and if I was still hunting prairie dogs in South Dakota I would certainly give it a try.
The .17 caliber is a solution in search of a use.. Too much for squirrels and rabbits but generally too little for woodchucks and coyotes…
do you know how many woodchucks ive taken with my 17 wsm and the 25 grain bullets.. many… and they do not go anywhere!
I read it. Somehow I missed the part where the .17 HMR is the clear winner.
Rimfire shootout I’d like to see next? 32 vs 41.
Did I miss the (more valid) .17HMR vs. the .22WMR comparison?
Still don’t know why you’re ignoring the .22WMR.
I feel it’s the more useful caliber for practical situations.
For me there is just no comparison – I’ve never been able to hit anything with the 22 magnum, and I’ve tried several brands of rifles, but the Savage in .17 HMR is just fantastic for prairie dogs! The report is the primary reason I like it – because of course a .223 would do better, but once you shoot the little critters just don’t come backup. With the .17, they got confused, and even a little curious. It was like they thought the bullets were pesky bugs, and they wave their paws at them when they heard them fly buy. Must have thought they were gonna get stung. Well they did eventually – I was hitting them over 75% of the time at 175 to 200 meters; so I always got out the .22 LR first, then the .17 then the .223 for later in the day, when it was about time to quit anyway.
This is exactly why I am considering the WSM. I start shooting the 17 HMR, but after 2 mags, the dogs usually push out of range and I have to resort to the .223. After 6-10 rounds, they are pushed out of the .223 range. We then walk and start the process again. It would be nice to carry just one rifle.
It would seem that if the WSM were brought out in a .22 caliber, using the 45 grain bullet, we might not have to reload the old .22 Hornet anymore. Why not?
Wendell, I love that idea!!!

I too, think that would be the ticket to the heavier rimfire shell. I am not so sure you could use the 45gr bullets, but more like the 29 and 30gr projectiles would still keep the fps up hot and fast.
Now I must admit though, I am a .22 Hornet fan. Something that close to a Hornet, but a rimfire; would be interesting if the ammo ain’t a quarter each. Guys, I like to shoot… One quarter per round is not cheap @ rimfire…
