17 caliber "cop killer?"

[carterbeauford]

Time to call mythbusters?

.17HMR is not common enough for even the media to be worried about this. Even if someone did label it a cop-killer, it can't do anything a .223 can't as far as penetrating a vest.

Them thar newfangled .30-30 Winchesters using that newfangled smokeless powder stuff will also penetrate soft body armor up through NIJ Level IIIA... :eyes:

I wonder if your instructor is misremembering some Bradyite propaganda about the 5.7x28mm? (Which won't even penetrate NIJ Level II with civilian ammunition, BTW.)

"Where on earth does one find FMJ .17 rimfires???"

At wallmart of all places, they are made by Federal.

Don't think so.

I did find it, though I've never seen it in stock at any gunshop, sporting goods store or box store.

It is made by CCI.

I've seen the 17hmr FMJ's for sale at a gun shop and I think at a walmart. They're for shooting a critter you don't want to blow a large chunk out of.

What about a 17 Remington?

A 25gr FMj bullet at 4,000+ fps sonds a littel nastyer.

I have a .17 rem. While I've never found .172" FMJ's for handloading, I suspect they would behave much the same as HP's and V-max's. The velocity is just so high (4,235 avg. w/ 20 grain handloads from my 700 LVSF), I imagine any jacketed bullet would fragment on impact with a soft target. However, expanding type bullets frequently stay in-tact when penetrating more dense barriers, so they would very likely defeat armor. For that matter, I bet the HP's and poly tipped bullets would, too. These things come apart when they hit a praire rat, but I have also punched holes in steel T-posts with the same loads.

You ought to see what those 20 grain V-max loads will do to a bunny, though. The word "mist" comes to mind........

It still amazes me how many STUPID cops keep brining up vests. They are there own worst enemy telling every nitwit what will penetrate a vest never mind that any 22 will penetrate their fore heads.

Get of the vest bit so idiots will forget that cops wear vests.

Any knowledgeable type knows just about any rifle caliber slices through them like butter.

I think a lot of this all came about because of the relatively new FiveSeven caliber from H&K. Last I heard, there were two types of bullets available- one steel core for LEO, and one lead core for the rest of us.

Having neither first hand nor reliable second hand information, can anyone else comment on this?

There was

an account of a guy who got shot in the leg/hip with a 17 Remington, and it did surprisingly little damage (pretty much all superficial).

Just because a bullet is FMJ, doesn't make it ap or non fragmenting (jackets can be thin).

The 5.7 is FN (4.7 thingy is HK?).

The cop killer bullet crap is nothing new. The 57 has kinda revived it.

 

[Steamship Trooper]

atblis, you are right. It is FN, not H&K.

Still, anyone?
