Reloading the 5.7x28
I found a source for a die set for this caliber. Evidently C&H Tool makes it. But I haven't a clue if any sort of reloading data or components are available. Anything else shoot a 5.7mm projectile?

Anyone seen any reloading data at all for this caliber?

AZ COLLECTOR 12-18-2004 06:58 PM

the 5.7 is the same as .223 as far as bullet dia goes.
think 22 hornet or 218 bee bullets as far as reloading simular velocities.....
not sure on powders yet
looking at starting with W748 figureing it is slow enough to start and planing to work up from there. also please not MidwayUSA is selling RCBS dies for the 5.7x28 will post on them as soon as they arrive....odd size rim too...thinking same as 25acp for rim dia.

Actually I did find a source for a die set (made by C&H Tool) but I haven't followed up with an order for one.

Are you sure about the diameter of the projectiles for 5.7x28 being the same as .223 (.224)? I thought I measured them and there was a difference, but darn if I can remember how substantial it is.

One of the reasons I never followed up on the reloading die set is because I wasn't sure any components were available, much less loading data.

Please let me know if you find out any more concrete information on this.

I assume you have a FiveseveN? :)

AZ COLLECTOR 12-18-2004 09:40 PM

i do have one ........
will mic the projectiles real quick here.
but if i remember right the issue of "5.7"mm was just rounded 38spl is a .35 cal projectile just sounds new better and different.

OK put the digi caliper to it best i can do at home....

it is only acurrate to .001 +/- .0005

still got .224 for both

thinking i am going to have to fill several 5.7X28 cases with water and see what the capacity really is. just eyeballing it thinking .221 fire ball .218 bee and i think it is a little more than the .22 hornet.
funny thing is they list H110 for the hornet....wondering if W296,H110 might be the ticket other thoughts are 2400 or 748....really unsure thinking the 748 will be too slow....don't really wish to blow up or damage my IOM just yet :rolleyes:

any other thoughts from others....this is new territory for me.

AZ COLLECTOR 12-18-2004 09:47 PM

oh and i forgot...
never used C&H dies....suger yes dies no :)
how do they compare to RCBS....hornandy...and lee?
that will get you to the RCBS 5.7 dies


that will get you to the 5.70/.224 referance that makes me a little more sure of my digi calipers measurements.

only thing left is finding the lightest bullets possible best i can do so far is 40gr....and thinking they should be designed for .22 hornet speeds.

other opinions and sage like wisdom always welcome.
have a nice day

[QUOTE=AZ COLLECTOR]oh and i forgot...

Why the admonition against C&H? I have a set of their .50BMG dies and got them AFTER rejecting the RCBS die set. With the RCBS dies I was snapping and pretzeling decapping pins about every third case. Haven't had a bit of problem with the C&H die set at all. Also bought a .50BMG case trimming tool from them as well that works well. Haven't had a bit of problem with either the stuff I got from them nor in dealing with the company itself.

Sounds like you had a bad experience?

AZ COLLECTOR 12-19-2004 01:38 PM

did not intend to flame C&H :bawling:
please note i wrote
[U]never used[/U]

could also be written as "have no expirience with them." will attempt to be more clear in my posts.

please accept my humble apologies (no sarcasm intended)


Rich Z 12-19-2004 03:49 PM

Oh an apology on my part as well. I think I read more into your statement then you intended to imply. :headbang:

On track of this thread, I thought I saw the 5.7x58 die set on Midway's website a little while back and it was rather expensive. Sigh, would be nice if standard .224 projectiles would work for reloading. But not sure I like the idea of experimenting in a roughly $800 gun...

BTW, have you picked up some 20 round mags for your IOM yet?

AZ COLLECTOR 12-19-2004 05:20 PM

got two of them when i purchased the IOM
and ordered a spare 20rd.... :bawling: they would only let me purchase 1 spare 20rd :rolleyes: i tried several more times seems the 20rd mags still a little scarce.

went thru CDNN to purchase weapon as i work part time for a gun shop doing repairs, cleanings, fitting....ect. helps me hone my gunsmithing skills and it's amazing how much I learn just listening to the old timers and factory reps( the latter can be full of BS)

well nice to know we arn't still :argue: about C&H

and as soon as the dies get here from midway i'm gonna start working up some loads...thinking i forgot to order a shell holder with 'em oh well. :headbang:

have a good one

Rich Z 12-19-2004 06:43 PM

Man, I wish someone would come out with a little carbine in 5.7x28. Something like that Beretta Cx4 Storm would be a real fun toy in this caliber. I'd buy one in a heartbeat.

This is a pretty interesting caliber, but it won't survive for long if other guns aren't made that will shoot it.

Rich Z 12-19-2004 06:51 PM

BTW, here's a photo I took a while back comparing the size of the cartridges for 5.7x28 and .223...


AZ COLLECTOR 12-19-2004 09:23 PM

that looks like a umc .223

funny thing i was thinking the same thing when i bought the pistol....ammo may not be around very long. :bawling:
so i bought 2100 rds of it. will buy another case when i see which way the market is going. figure 4200rds of brass should keep me busy for a while.

i gotta assume you have one too.....after shooting a few clips have you noticed the brass dust( or flakes) in the pistol on cleaning?

i am thinking an stainless revolver would be amusing in this chambering. taurus seems to like to make odd ball revolver chamberings we may have a chance if they see a demand. i think the demand may become reality if the ammo price lowers a bit.
would make for an interesting pen gun as well. :dgrin:

aditional side note HK is making a 4.5mm as well not sure but is that about .20cal? Had a US army guy bring a handful of empties. seems the army is testing out HK's new toy at the Yuma Proving Ground. :uzi:

Rich Z 12-19-2004 10:58 PM

Well, look at it this way. If the ammo becomes obsolete, in 30 years you could probably sell it as collectible at $1 or more per pop.

I wouldn't mind seeing a semi-auto FN P90 hit the streets. Now that the high cap mag ban has gone away, maybe that will happen. Long shot, I know, but with a 10 round limit, no way that puppy would show up in the marketplace. With a bullpup configuration to keep the 16 inch barrel from looking downright weird, I think it would look OK.

Wish they had come out with a carbine and scrapped the idea of a handgun right off the bat so the steel insert cartridges wouldn't have gotten tagged as AP. Not that I think they are any more AP then an SS109 .223, but then again, I never did understand the logic of what designates a "penetrator" and another as "armor piercing". Heck, if body armor is the determining factor, then throwing darts could be considered as armor piercing.

Yes, I have an IOM. But sad to say I only shot it once and planned to shoot it again real soon and didn't clean it. That was a couple of months ago. :crap: I sometimes worry about how many other guns I have done this too and really need a good cleaning before YEARS go by and I pull them out again.

It's a real fun gun to shoot, so I really should make an effort to play with it again soon. Really pretty accurate as well, as far as I could tell from my informal plinking. I really wouldn't mind getting night sights put on it then have it as my "nightstand" gun.

AZ COLLECTOR 12-20-2004 08:39 PM

well forgot to order the shell holder.
there is always tomorrow to get one i guess.
so far the funniest discription i have heard of the 5.7x28 is lol
a stretched ou 25acp blown out and necked down.

Rich Z 12-20-2004 09:34 PM

Hey, please let me know if this is a "one of a kind" shell holder or if something common will work with it.

AZ COLLECTOR 12-21-2004 08:39 PM

well midway is announcing coming soon for the shell holders.

in the mean time you wouldn't happent to have lyman #32 shell holder would you?

it is meant to fit 25acp

the two case head sizes are really close not sure but it would be worth a try.
my local shops here don't have one in stock and midway claims special order 30 day waiting period. gonna order one anyhow but if you have access to one this part of the subject could be layed to rest.

AZ COLLECTOR 12-24-2004 11:32 PM

update on reloading equipment

the 25acp case holder is a little too small
can and has been opened up as a hack job( dremel and patiance)
this is a really ugly method but has provided me with something that is still awaiting delivery according to midway usa.

anyone who has any wildcatting knowledge please feel more than free to chime in. will not hold anyone responsable for any failures do to thier suggestions.....after all i think this is largely uncharted territory as of now.

since this is a blowback operated pistol i intend to start with low power loads. that way the worst that should happen is the slide fails to cycle fully.
if anyone disputes this i am all ears. will be doing first run with a 40 grain hornandy V-MAX have some 35 grains on the way.

have not selected powder yet but winchester small pistol primers will be used. if i see pressure problems at the primer end...will try small rifle primers and a further reduced charge.

have some more research to do concerning powders.
more updates later.

Rich Z 12-25-2004 12:21 AM

Did you check with C&H to see if they have a shell holder? I'm glad you mentioned it because I may very well order a die set from them and would want a shell holder along with the die set.

Heck, maybe I'll remember to measure those projectiles. I have a real nice micrometer so I should get pretty accurate readings. I know I did that once before, and I thought there was a 5/1000ths or so difference between the 5.7 and 5.56.

Going out of town for Christmas, so I'll try to remember to do that on Sunday.

AZ COLLECTOR 12-25-2004 04:26 PM

please do measure as i posted earlier my digital calipers are only acurate to .001" +or- .0005"
and thank you for the posts at least i have someone to chat with as i work tward a possible rapid and unintentional disassembly of my newest toy.
never suffered a KaBOOM by my own reloads but did start reloading as a result of purchasing reloads that resulted in a KB of one of my pistols. fortunatly the pistol had a magazine foward of the grip and my hand was intact after words. it did dewstroy magwell and frame however irrepairably.


andy 12-25-2004 05:33 PM

too big a waste of time and money for me. Can get the same ballistics out of a 9mm, with the right bullet. High velocity does nothing for the REALISTIC range limitations of the pistolero (when he's under fire0 Everybody misses the chest (a LOT ) at a mere 25m, when under fire, no cover, no ear protction. In fact,most shots miss the chest at 10m under those same conditions.
