17-223 info and questions

[Bill K]

Agree with Gary, 223 brass would work fine and it can be found all over the place, compared to 17 Rem and reworking it down. Keep it simple and enjoy.

it's been a while since i owned a 17/223 but the shoulder sets farther forward on the 17/223 than the 17 remington. i made some 17 remington from 204ruger a while back and was running a 25% attrition rate. if you make 17 rem from 223 you will have a short neck.
as you can see from the pic the shoulder on the 223 and the 17-223 ackley are the same.
i picked up 1000 223 cases the other day at the rifle range, mostly lake city and it was free.

It looks like your approach to making brass will get you where you want to be with a full length case neck, Al.

It sounds like a cool cartridge. I hope it shoots good. Enjoy..!!

I'll take a half dozen of the reformed 223 cases, expand the necks over a .169 mandrel, get some sort of fast-ish powder in there and seat a bullet hard into the lands (got a gaggle of the original Hornady hollow point 25 gr. bullets so that will be a good use for 'em). We'll see what comes out.

Should put it in some sort of stock to test fire it. But the full-tilt- hillbilly-dirt-clod method might get pressed into service.....

Good shootin' -Al

But here's where the issue lies. I shortened a 17 Rem f.l. die today and pushed the shoulder back enough on some virgin 223 cases enough so they would just chamber. In this pic, you can see the chamber cast I did this morning and a couple of the reformed 223 cases....the necks on the reformed 223 cases are right at .040 shorter than the chamber.

As I mentioned, this chamber retains the original .17 Remington's .260 neck length. It's not a plain vanilla 17-223. It's actually a shortened .17 Remington.

How does this compare to a 17-222?

Will be interested in hearing how she does speed wise with the 25’s.
Thinking it will be a good shooter especially with you in the drivers seat.
Looking forward to seeing how you stock it,I used a McMillan BR-50 for my
XP-100/17PPC and it was a good fit.

About the brass situation......

I'm thinking some 204 stuff......or 222 Mag.(Sako if you can find any)..............or some of the old Fed. 6x47(I'll almost bet you have some stashed away somewhere).

Getting the necks as long as the chamber will allow, may help getting closer to the lands. The 6x47 brass may help fill that 0.205 neck diameter.

Just my lousy $0.02.

(edit: About that bolt handle.............ugh! )

Nosler Pro Shop had some 222 Mag brass for sale in their recent e-mail.

The five cases f-formed up very nicely. Lightly oiling the cases, a bunch of faster burning power in them, a hard jam-seat into the rifling, .006 neck tension and a .003 'crush' fit into the chamber let the shoulders blow forward to match the chamber angle. The necks actually lengthened from .015-.018.



Came home and made another 45 using the same process. Annealing after forming and expanding over a .169 mandrel:



Swizzled 'em in acetone to clean and dry 'em:
