Everyone go buy a .17 HM2, not a HMR

Hmmm... Shopping for things to fill up the safe...

Since I can find all the rimfires cheap, and wouldn't mind a 'convertible' 10/22...

Anyway, how do the couple .17's match up against .22 magnum? Always see them compared to LR, but considering the price some of the .17 ammo can get to, a Magnum might be a better by-price comparison.

"Anyone know what would happen if mach2 rounds were fired in HMR rifles? Basically the same bullet?? except the case rim is slightly smaller.

They are NOT interchangeable. .17 HM2 is a necked down .22 LR. .17 HMR is a necked down .22 WMR.

The WMR case is wider than the LR case. Basically, don't do it. A .17 HM2 will not properly fit in a .17 HMR chamber.

See if you can dig up a picture of the two. You'll see they aren't even similar. The HMR round is twice the length of the HM2.

The .22 WMR doesn't shoot as flat as a .17, but it hucks a much bigger and heavier bullet. SJHPs are readily available, too.

I don't think that the .17s and the .22 WMR are all that interchangeable, either direction.

both 17's are faster at 100 , than a 22 mag is at the muzzle. they both have less wind drift. they both have better trajectory. Energy inside of 80 yards, belongs to the 22 mag, after that, the hmr takes over in energy; the mach 2 is slightly around the same or lower energy.
See, the prob is the 22 cal round itself; it has such terrible properties, that a few things happen
to the 22lr round or 22 mag round, that don't happen to any other bullet out there- at all.
a 22 round gets so buffeted by the surrounding atmosphere, it is almost rediculous.
because of this, one of the probs of the 22 mag round, is that most of them, will fully dump almost 1/2 of it's speed, from the muzzle, out to 100 yds.

The .22 WMR, though, is more of a hunting round: heavy enough to work well on larger small game, not intended to be a long-range round.

The .17 HMR and its younger cousin are intended to be used more as varmint rounds.

yeah the hm2 is a nice round it works for somethings haowever it doesn't do what the hmr can.

Rangerruck, thanks for the info, sounds expensive...I figured it would take a new action spring and barrel, not the whole dern rifle.

Secondly, do not fire the 17M2 in a 17HMR, the Mach 2 is based upon the .22lr and the HMR on the .22 Magnum, so don't try it.

The M2 isn't suppose to do what the HMR can. M2 up to a 100yds and HMR past 100 if your going to eat what u shoot.

Basically , you need a new bbl, a new guide rod spring, new hammer, new weighted bolt assy., and bolt handle. All due to the much longer, and higher pressure spike.

After further review, the weighted bolt, handle, and action spring is all one assembly so it isn't as bad as I thought. Are you sure you need to replace the hammer (upon researching the conversion I have found nothing indicating that you need to, but want to make sure)?

... it depends, some guys have had some probs with their conversions, as far as timing goes, which affects loading and ejection. a new hammer, with correct geometry, and weight, can correct this prob someitmes. so it is not so much a neccessity, but could be needed. You can proly do a conversion, for 150 bucks, if you shop around, certainly under 200 can be done.

Thanks for the additional info, looks like I may be going this route after I get a new .22lr. After which I plan to make the 10/22 into a target gun...and the .17M2 would suit this end perfectly. I would like to put a Shilen Bbl on it but I think the cost may be prohibitive, so I need to expand my sarch. Personally I Lothar Walther barrels better, but it seems that they (as well as Krieger or any other good target bbl manufacturers that I know of) don't build a 10/17 barrel, and I am definitely not willing to sink the extra cash into finishing a barrel blank.

i got a savage mkII .17mach2 bolt rifle last year and i love the way the thing shoots!! that fast 17 gr bullet shoots so much flatter than my .22 ruger custom..... get a .17 mach2 and you won't regret it...... i do need to get a wood stock for my mkII... the tupperware stock really isn't what i'm wanting now.... it's nice and light and easy to handle though.....

LIFE IS SHORT.....

go over to rimfirecentral, go to the 17m2 threads, and look for Skeeter. Ask him who he recommends for parts. He has done more testing and research, on the round itself, worked with Eley, and done more 10.22 conversions than anyone else I know.

Yeah, as long as you don't have a Gmail, Hotmail, Yahoo, etc. email address...

Oh, and they want you to put your birthday in there and apparently there is age discrimination going on because when I put in 1901 as the year of my birth, they told me it was invalid.

So... I will continue to get my info here where I can control what information I put out on the web.

Yep, I don't care for that too much myself. Gmail is all I use, despite having half a dozen others. IIRC Sniper Central is the same way.

For decades and decades ammo companies tried to build a better 22...and the new rounds always end up dead or, at best, as niche cartridges (including the 22 magnum)

The only really commercially highly successful improved 22s are the high end 22 LR themselves, CCI and Aguila are a clear example....even before the "ammo crisis" that hit us, it was hard to find the Interceptor or the Velocitor in stores...not because of rarity but because they were literally flying off the shelves!!! And the sight of unsold HM2, HMR and even some of the 22 Magnum boxes was fairly common.

Some shops around here (Western WA) quit selling HM2 and HMR altogether...

None of the new wonder rimfires can beat the flexibility of the 22 LR, period....from cheap $1.49 a box 40 grainers to shoot by the thousands to the Interceptor and Velocitor...

The economics are just not there....again, talking about pre ammo crisis time, the cost of the new supposedly "better" rimfires were dangerously close to some centerfire territory (cheap .223, 22 Hornet, etc...) that give you way better capability...

And the success of the pistol round based carbines does not help either...a 9 mm carbine that can spit 115 gr. pills at 1700+ fps is a better gopher stopper than any of these .17 pins....and it can be a serious HD solution as well...

On the other side, the newer hyper velocity 22 LR 40 grainers at ~1500 fps serioiusly reduced the gap in terms of long range trajectory...

So, if you need a varmint round that is silent because of neighbours, that can stretch by couple of dozen yards the effective trajectory of the fastest 22 LR but becoming harmless at 250+ yards, and you are engaged in artistic grass red painting, yes these newer rimfires may be what you need...a niche indeed...

P.S.

I heard that Aguila is coming with some sort of ballistic tip ultra light (20-25 gr???) hyper velocity 22 LR....unknown accuracy though....


SureThing

It's interesting that you compare the trajectory of the super 17s with the basic $1.50 a box 22 LR....why don't you get the Velocitor, Interceptor or the Viper in the mix???

Ok, so I just bought a Savage Mark II FV and a Leupold Rimfire 3-9 EFR scope. When they get here and I get the scope mounted, I'll see if I can't get out to the range to see for myself.

I would have to agree that the mach2 is a great round, I can honestly say it’s the one gun that ALWAYS leaves the safe when I go hunting or shooting, why? Its cheap and deadly accurate, whoever said Mach2 costs more than 22lr is full of it, good 22 hunting ammo (Vipers, Stingers, Mini Mags, Yellow Jackets) are always $4+ around here, almost the same as Mach2 if ordered over the net, but the kicker is the 17M2 I have is every bit as accurate than my comparable 22 but that rifle likes high end match grade stuff costing twice or three times as much.

I have killed more squirrels, gophers, crows, rabbits, prairie dogs ect with this rifle then I have any other, I’ve also shot tighter 50 & 100 yard groups with this gun than any other I own, and I own a few nice guns and have worked up some pretty impressive loads on my bench. I do own a few HMR’s and both are very fine shooters and do drop wood chucks a bit better than the mach2, , but both are heavy thick barreled guns and when I can get just as good of accuracy with the smaller lighter rig I tend to bring it out every time, not to mention it’s a semi auto and being a rimfire the follow ups are easy as pie, staying on target for the follow up is a breeze.

I could preach to the day I die on how much I love this rig, its just that fun to shoot and hunt with!

Ruger 10/22, Predator Raptor Stock, Volquartsen Carbon Fiber Bull Barrel, VQ trigger (no other parts replaced in trigger group), VQ mount, Weaver Classic Extreme 3-9 X 50mm SWF

So who makes the best 10/17 barrel for the money...I have tried Rim Central but will NOT give my work e-mail just to join. Been looking at the kit from EABCO, but don't know who built the barrel. Any thoughts?

Nobody said that the high quality/high performance 22 LR cost less..you need to pay for quality....but with a 22 LR I still have the opportunity to fire the really cheap stuff for fun or plinking....this is what it makes the older rimfire truly unbeatable and I do nto foresee any new cartridge soon that is going to change the 22 LR overwhelming market dominance in this segment.

7 people out of 10 (if not more) if they need more varmint punch, once they need to buy a new rifle anyway, they are going .223, 22 Hornet or a pistol round based carbine like a 9 mm or a 357 Mag....

well, for a mach 2 bbl, there are some great ones out there; but you may wanna look at the volquartz. Though expensive, they went through the round specs proly harder than any other bbl maker, and i believe they put a self regulating spouthole, just up front of the chamber, to stop the nasty habit of Kabooms!!! that can happen in a semiauto 17, which is scary as hell.
If I were building a 10.22 conversion I would either go with this, or with the ones skeeter is building for chargers, or any that he recommends.
just look over at the 17m2 threads, and just look over the bbl comments; see what he agrees with. No need to register.

I've got a Browning BL-17 that I picked up a couple years ago from CDNN and love it. I haven't pulled the 22 out of the safe since I got it.

Got registered at Rim Central, still can't find any info on a decent barrel choice, the site is horrible...can't post a thread...can't search for anything. Might just stick with .22lr just so I can get a Green Mountain bbl.
