17MII conversion

[PHATINJUN]

Some thing I have been thinking about doing to this extra 17MII is turning it into a 17HMR is this possible ?Also  with the centerfire throats being so long in most NEF's do they do the same thing to the rimfire rifles as well.... as how far the lands are from the bullet? Kurt

Kurt,
I don't know the answer to your question, but you might consider looking for a trade for a HMR barrel.  The M2 isn't available as an accessory barrel, so you might get some takers.

Kurt,

you are cutting it close if you are trying to get a 17HMR ready for the p-dog shoot

The 17M2 barrel IS available as an accessory barrel, it's just not on the web page, there are lots of errors and omissions, that's one of em. Its part #R03264.

The M2 and Hmr chambers aren't the same diameter, the M2 is based on the stinger 22Lr case, the Hmr is based on the 22mag case which is not only longer, but bigger in diameter. The chamber would need to be reamed, the cost to have it done would be a good portion of what an accessory barrel would cost.

Thanks guy's I was just thinking out-loud.  d_hiker would of been nice to have one for p-dog shoot but hopefully we will be able to start off half way close to them pups and I can use the m2 then bring out the heavies . Kurt

This looks like an oldie.

BUT:
  Don/Kurt:

I bought both an HMR and M2.

Took awhile to decide which one to screw up, but, chose the HMR barrel to rechamber.

Have you seen the 5.7 FN round yet?

The body is an even inch from base to shoulder, almost the same as the HMR is.  BUT:  it's a
centerfire, so it can be reloaded. Which is my goal.

I made some double ended bushings about .010" between size's and four steps to neck the case down to 17 cal=.196".  Then a final sizing in a factory 5.7 die to make the body right.

Am taking it to the fields in the morning, so far I've only fired about 20 in the shop to check the loads and chamber.  So far, it looks great.
Supposed to push a 20gr v max around 3000-3400fps with only 8-10gr 1680. 

Testing the loads I had a .410 action on the gun and was having cratering and primers backed out. Then reading a post by Quick that said shotgun actions create problems. So I put a .223 action on it and solved those problems.

This will make a dandy small .17 cal that can be reloaded. They're a lot quieter than .223 also. Plus the brass is thicker than a Hornet case. Though they are much harder to come by.  IF I'd known the hassles of finding enough brass I doubt I'd made this case the base. Would have gone some other close case and necked 'em down the same way.   Like maybe a Hornet and just live with shorter case life.

We'll see how it does on p/dogs tomorrow. Will report back after that.

sounds intresting keep us posted. Kurt

I have a 17MII barrel that has been rechambered to a 17 Remington. It shoots real good...

[LaOtto222]

Have you thought about a 17 FireBall? It is a round that Remington just brought out. It is based on of course the 221 Fireball. They used to call it a Mach IV because you were able to reach 4000 fps. It will reach 4000fps with a 20 grain bullet and about 16 grains of IMR 4198. It is 1.058" to the 30 degree shoulder and 1.400" overall. I think it is a little larger in diameter. You could buy 17 Fireball brass or make them out of any of the 222 family cartridges. It is something to you could chamber to if needed or wanted.

Well, the p/dog test for the .17x28 was a bust.
Shot paper at 100ft +- and got it right on. Then at p/dogs at 150yds and
hit waaaayyy high. So rather than waste ammo. Put it away til I can take it to the range
and do a proper zeroing and sighting tests. haven't had a chance since then.

My goal is to have a SMALL reloadable cartridge.  Sometimes a fancy horse rancher let's me shoot
among the pens and he don't like the blast from the .223.   I've been on Saubier.com a couple of
yrs now and those guys are deep into the little one's. Several have this same cartridge. They've also
sent me a bunch of cases in .17's.  I've got 23 different shells from .17Rem down to the dinky lil
.17x32S&W case the maker claims is worse than worthless, but, it shoots.

SO the fireball is out, because it's too big for my needs. Thanks for the suggestion though.

Since I used up the HMR barrel for this rechambering, I'm looking for another HMR barrel if someone
has one to part with.

This gun still needs some fine tuning on the extraction part, still not working like it should.

Thanks,

George

A bit more Update on this gun.

Took it to the range for some final working with it to get it zeroed and learn where it shoots etc.

Six shots and split three shoulders, then pulled a neck off in the chamber.

After discussing these things with a young expert. Have come up with the facts the neck of the chamber is too tight.  Mailing the barrel to this fellow to ream it out for more clearance.  mailed it today.

Gunsmith chambered it with a Dave Kiff reamer and fired case from another gun made with the same reamer. got a perfect cut. Til running into this problem. Expect it'll be right when it come's back.

Today, I also made two more trades on:  ammobrasstrader.com for 300 more 5.7 case's.
This will put me up close to 1000 of them. Should be about enough, that's the minimum I feel should be on hand to merit a custom cartridge.

Hey George, be sure to update your progress with this cool project!

No criteque on the custom 17, great caliber. But man I love to go to the store
and buy two or three bricks of 17HMR and shoot and shoot all day.

To load a thousand of those little buggers just make me gr-gr-inch

I have an ice cream pail full of 6x47 cases awaiting a refill, supposed to be a winter job, ma-by a spring job, but the 17HMR has been doing a fine fill in job.

[glwenzl]

LOL U-would crap if U see how many and what all I load for I have a centerfire version of the 17 HM@, one of the HMR, short med and full sized Hornets cases not to mention a few others... I also keep about 3 bricks each of the fun rimfire stuff on hand.... Never know when a PD war will begin and them charging PDs need all the medicine they can get!!!

Fred:
I don't like to spend money on ammo, especially not as much as HMR's cost. That's the main reason I go with centerfires so I can load 'em the way I want.  I enjoy reloading, and this is my first custom cartridge so am having a ball making case's from something else.
Some yrs ago a fellow came out to hunt elk with me from Wisc. Brought two boxes of each cal in the then new mag loadings:  243, 7mmag, 300win, and '06.  Since I flat refuse to shoot factory ammo I took them to the store and swapped 'em at his cost for reloading supplies.  Those 80 rounds paid for enough supplies to load 3 or 400 rounds of homebrews.

Update on the .17x28mm based on the 5.7 case.
Got it back from the fellow in Reno that reamed the neck out to .203" like it should be and the ejection wouldn't work right.  Shipped it off to one of our gunnie posters on this board for touching up. Tell's me by e'mail it's nearly fixed and looking good.  should be sending it back within a week. Am looking fwd to shooting it this time with some faith it'll work right.

Haven't made the deals yet, we're working on the details now for another few hundred 5.7 cases on ammobrasstrader.com.  IF you guys haven't been on there yet, you're missing out on a good forum to swap off what you have and don't use for things you do and need.

GLW:  thanks for the sample's that time.

wish you all well,

George
