    Dont, you will regret it, the 17HMR is a superior cartridge in all aspects, i know i found out the hard way.

    And for the Contrarian's View:

    Trade it! I own three 17HMR's that never see use but have no less than seven 22WMR's.

    A caveat is that if you can only get ONE kind of ammo, or have very limited access to 22WMR ammo, you should try some in the intended rifle first. They can be finicky. My daughter's Anny only liked two brands: Remington Premier 33 grain and Federal 30 grain classic. My CZ digests everything and is VERY accurate. My Savage Striker handgun (10") is also accurate with about everything. It depends on the gun. If you trade, be prepared to do some leg work but once you find the right ammo, you will find it very consistent. FWIW I hardly ever shoot 40 grain anymore. Thirty grain Federals HP's shoot tiny groups at over 2325 fps. Lights out on prairiedogs and rabbits.~Muir

    Really? Not sure about every aspect..

    Depends entirely on what you plan to shoot with it and at what distance and conditions
    I have both.
    I was a big fan of the HMR when they came out but its just not as fancy as the marketeers would have you believe
    HMR rarely comes out now...I will use it on a nice calm day when the crows/magpies are out between 100-175yds unless I have the .222 within 6ft of me!
    HMR is pointless on rabbits IMO unless you have no reason to pick them up (and expensive if you do!) and genuinely can't get within 100yds of them and not up to the job of regular foxing

    WMR trumps HMR by some margin for energy across the full trajectory. Thats it as far as I am concerned
    The larger drop at range is easily accounted for.
    My WMR is more accurate than the HMR, doubt it is the rifle as its a Sako Quad so I can only assume its the ammo....a known failing
    Never had a squib though thankfully
    WMR is not affected by wind or the slightest blade of grass as much
    Its Much cheaper to feed (which I don't understand at the bullets are twice as heavy as the HMR!)
    If you have a decent supply of RFD's locally you will find much more selection of ammo from VMax, GamePoint, HollowPoint ranging from 33gr up to 50gr. 40gr does the job

    WMR despatches bunnies without disembowelling them but has the punch to drop a fox without worry of surface splash wounds.
    It was my urban fox calibre of choice for several years


    as to the original question
    plenty of WMR and HMR's been chopped down to less than 16" without issue

    17 HMR is balistically superior to the 22WMR in all aspects except it is a little down on energy, as for saying the 22WMR is more accurate, you must have a really $hit HMR, no way is the WMR capable of duplicating the accuracy of the HMR its just not as inherently accurate.

    Having used the .17 HMR for some considerable time, and have after selling that on for a Sako WMR which I use full time, the Hornady 30 grn BT as standard ammo after trying all the other brands, there is one conclusion through time used and accuracy, the WMR easily outshines the 17, for rabbits they are about the same

    The 17 is not a foxing rifle I guess some would say look at the energy from the 17 but a 17 or 20 grn round which flutters around like a butterfly in a light breeze doesn't cut the mustard, The WMR I have found a good all rounder for rabbit or fox and a perfect calibre out to a 100 and extremely accurate and does the job admirably, the 17 doesn't have the terminal energy, accuracy. (Apart from ideal conditions) WMR will punch out to a hundred, it will go farther if your in to elevation, the WMR is by far the best all round for rabbits and foxes, I definitely wouldn't be without mine.

    I have used a considerable amount of ammunition through both calibres

    Friend of mine has a reduced barrel sako in synthetic, my thoughts were he altered the balance, for the worse, although the accuracy was still bang on, I have two quads in LR and WMR in wood and varmint barrels and the set up is bang on, can't see the need to shorten, balance and accuracy is faultless

    The WMR is just great , seems to moderate better than the HMR (don't know why?) I run a 16" barrel and it's fine , a great handy rim fire with great accuracy (30-33g ammo) and the punch for Charlie if required .

    you may loose a little velocity (but I doubt it at 16") and as long as it's shortened and recur owned properly accuracy will be the same or better (shorter barrels seem to shoot well in my experience)
    Right where's those stones , I'll start !

    What makes the 22WMR "inherently" inaccurate?? Or not as inherently accurate?? Straight case? Lack of a boat tail bullet?? If those were what made a cartridge inaccurate then a 22LR with it's heeled lead bullet should be little better than a thrown stone.

    You are right in a different sense. The 17HMR has the potential of being more accurate, or uniformly accurate, than the 22WMR. The reason is that there is one manufacturer of 17HMR ammunition being used in one very specific chamber with specific throating, and specific bore and groove dimensions. The 22WMR is plagued with almost 40 years of *******ization. Guns made with .220" grooves, .223" grooves, and .224" grooves. All different bore diameters; companies adapting their 22LR barrels to 22WMR with simply a reamer.

    It is because of this that if you are going to buy a 22WMR, you must be willing to seek out the most accurate ammunition. Like a CF weapon you need to find what works in your specific gun. ~Muir

    This is my Remington 597 in .22WMR. It's a great little foxer for ground that's restricted to rimfire. The barrel is 16". Shortening it reduced the velocity slightly but improved accuracy markedly -due to a better crown certainly and a stiffer barrel probably- and it now shoots well inside an inch at 100 yds with Remington Premier 33-grain polymer tipped loads. It's effectiveness on foxes has therefore been enhanced rather than diminished by the change.

    Hi lads thanks great imput.The rifle will be used for rabbits and sub 120 yard fox work as i have a 22.250 for way out yonder.i would agree that the 17hmr is way over rated and NOT suitable for any kind of fox control at all unless you stick the barrel up its nose!! im going with the anny in 16" and i have a good supply of ammo i think i will try maxi mag +v 30 gr first

    Thanks again lads Nigdonn

    22.250/243/30-06 /303. 17hmr? soon to be .22wmr.
