What's Happening Here Then?

This is a 17HMR SEMI (also available .22WMR)

 

So what's the deal, I understood HMR semis were stopped on safety grounds almost as soon as they were introduced, what's changed?

 

Yes, I know, it is hardly going to effect the UK, but the ammo does, and implications certainly suggest something!

What is the safety issue mate?

HMR Squib rounds and blocked barrels, that's why they stopped them years back!

Oh that, yes. Perhaps they are confident the ammo is ok!

 

Or they made the action able to cope with a blockage.

Dunno??

If it's a flyer (see what I did there?) it might increase the ammo output to cope with it.

 

What I don't like is the testing at 50yds for a so-called 200yd cartridge.

All I can really see here is the possibility that a squib round may not produce enough blowback to operate the system so it will be a simple jam, rather than anything more dangerous!

 

I would like to know more!

I'm not sure who has suggested HMR is a 200yard cart, it certainly has the energy to stop any small vermin, even fox at that distance BUT.......

 

.....even though I have used it many a time at the range at 200, and admittedly a handful of times in the field at that distance, I personally, and definitely, do not see it as a go for, daily, 200 yard cartridge.

"When introduced, we thought so much of the .17 HMR we put a single, diminutive cartridge all by itself on “the white cover,” calling it “The Little Cartridge That Could” (March 2002, p. 48). Necking down the .22 Winchester Magnum Rimfire (WMR) case to .17-cal. with a 25 degree shoulder and stoking it with Hodgdon Lil’ Gun powder resulted in a 17-gr. V-Max bullet moving out at more than 2550 f.p.s.—a huge and efficient leap in rimfire ballistics. Thanks to then-new high-energy propellant and a modern, jacketed bullet with a good ballistic coefficient (not a misshapen hunk of lead from a previous century), the new cartridge was the first 200-yd. rimfire. Marlin and Ruger were in on the development, and both introduced bolt-action rifles concurrently with the cartridge’s launch. Many other companies have since added guns chambered for .17 HMR, but the real payoff for this cartridge was getting it into semi-automatics. After all, a big part of a rimfire’s appeal is affordable, high-volume shooting. So making a semi-automatic .17 HMR should be simple, right?"

The groups at 100/150yds might even deter most folk from shooting at the longer distances which of course is precisely why they don't do it.

The rifles I saw (in USA), are not a simple blowback action, it has a locking lug that cam releases after the round is fired, just like a semi-shotgun.

So the issue of over powerful for blowback actions is overcome.

They do it in 17 HMR & 22WMR.

We can't have the 17 in S/A but I think the WMR would be OK, (not for me though).
