Recovered Reloading Data

[Wollychop]

This is data that I collected when I began reloading the 5.7. I do not claim authorship of any of it. It came off of the old http://www.fivesevenforum.net" onclick="window.open(this.href);return false; domain, and represents the work of others. Use at your own risk. I did use much of it as a jumping off point.

Thanks to all who broke ground in reloading this cartridge so that the rest of us can have fun!


Powder: AA 9.

Bullet weight: 35grains. V-Max

Start load: 6.8 grains (5" - 1700 - 1800 ft/p/sec) (10" - 2400 - 2500ft/p/sec)

Maximum load: 7.8 grains (1900 _ 2000 Ft/p/sec). (10" - 2400 - 2500ft/p/sec)



Bullet weight: 40 grains. V-Max

Start load: 6.5 grains (1600 - 1700 ft/p/sec) (10" - 2300 - 2400ft/p/sec)

Maximum load: 7.5 grains (1800 - 1900 Ft/p/sec). (10" - 2300 - 2400ft/p/sec)


Hornady V-Max 35 grain
6.9 grains AA7
CCI 400 Primer (small rifle)
COL: 1.46 inches
Case trimmed to 1.127
1884 FPS (Pistol)


40 grain Nosler ballistic tip, HS6 powder, CCI SMP primers, 1Xfired cases

6.5 grains yielded 2283, 2306, and 2352.

Factory duplicate load for SS192 round is:

7.0 grains of Accurate Number 9, Hornady V-Max 35 grain bullet,
CCI Small Pistol Magnum Primer.
This load yielded a 20 round average of 2420 FPS on a
CED Mellinium Chronograph with Infrared sensors @ 20 ft from muzzle.
Group accuracy of 4 inch circle at 100 YARDS, Shot from a bench rest.
It shot virtually a flat trajectory !

DO NOT LOAD THIS ROUND ANY MORE THAT 7.1 GR.
OR ANY LOWER THAN 6.9 GR.
More will crater the primer. Less will detonate with uncontrolable pressures.
Use of rifle primers will lead to misfires due to light firing pin energy
in this gun.

Load for duplication of NEW SS196 SR round is:

6.6 grains of Accurate Number 9, 55 gr FMJBT Sierra Bullet,
CCI Small Pistol Magnum Primer.
This load yielded a 20 round average of 1450 FPS on a
CED Mellinium Chronograph with Infrared sensors @ 20 ft from muzzle.
Group accuracy of 7 inch circle at 100 YARDS, Shot from a bench rest.
It shot 3 inches low of bullseye ! It was One inch low at 50 Yards.

DO NOT LOAD THIS ROUND ANY MORE THAT 6.8 GR.
OR ANY LOWER THAN 6.5 GR. More will crater the primer.
Less will detonate with uncontrolable pressures.
Use of rifle primers will lead to misfires due to light firing pin energy
in this gun.
Please use extreme care when using this data.
Accuracy of this load with this powder can NOT be Stressed enough !
Accuracy with this powder is a MUST !
It will shoot beautifully when loaded properly !

55 grain Winchester FMJ, HS6 powder, CCI SMP primers, 1Xfired cases

3.6 grains yielded 1209, 1302

3.8 grains yielded 1320, 1341

4.0 grains yielded 1366, 1344

4.2 grains yielded 1410, 1451

4.4 grains yielded 1520, 1564

(These loads all were very mild. The primers were almost like they came from the box with the addition of the firing pin strike. Very mild recoil and quitest load tested. I will deffinately run the powder charges up to 5.0 or 5.2 grains of HS6 in 0.1 grain increments watching for pressure signs. This combination has to be the cheapest 5.7 loads to put together. It was very accurate, 20 rounds of 55 grian stuff in an inch at 25 yards throughout the progression. No sign of tumbling. 1600 FPS and beyond is deffinately feasable.)

Thanks Wolly! Im really looking forward to trying the HS6!

[f3rr37]

I wouldn't use HS6 for supersonic loads, just subsonic.

[Grantness]

really? why?...the post talks about getting 55gr FMJs up to 1600.

[f3rr37]

I've loaded HS6 w/55grain FMJs and have had lots of FTE's. Seems like the hotter you try and load them the more they FTE.

[Grantness]

Has anyone tried 3N37?

[f3rr37]

Has anyone tried 3N37?

From the old forum:

If you're thiking of using 3N37 for 55 grain loads then you need to read the 55 grain thread. I've loaded about 50 rounds with 3N37 and when I passed 1400 fps (4.8 grains) the rounds just stopped ejecting. I tried CCI 400 and WSPM primers with the same results. It's just too slow.

That post was by Rnelson11 dated 02-22-2006.

I think Ramshot Trueblue is overall the best powder for this round, I think MO uses something else for his subsonic loads.

[Grantness]

3n37 is not too slow...its faster than True Blue and slower than HS6. But I dont doubt his results.

Thanks for that fuzzy. Very helpful. Ive been looking at accurate no.7 for my loads.

[f3rr37]

No problem Good luck, let us know how it works out.

[Grantness]

anyone have any data for HS6 and 45grain bullets?

http://www.gunsandammomag.com/cs/Satell ... agenum%3D2" onclick="window.open(this.href);return false;

[Grantness]

thanks blkbd, that was really helpful! it just so happens that I used the same start and max loads for my rounds...what a pleasant surprise. One thing though...can anyone figure out what they really meant to say in two right-hand collumns? They both say max pistol muzzle velocity. Is one of them the start pistol velocity and the other the max pistol velocity, or is the one on the left the max pistol velocity and the one on the right the max rifle velocity?

I suspect it is max pistol and max rifle....but I see some problems. They are saying that the max pistol for a 40gr Vmax with 6.8 grains of Accurate #5 is 1800 fps. Accurates published loads (for the pistol) have 6.5gr of #5 pushing a 40gr sierra sp hornet at 1975max.

[Esteves]

I remember reading that article and discussing it before "the crash."

It's worth noting that the author did not use an FN COTS platform for load development. He doesn't mention the test gun(s) specifically, but I'd guess a T/C or other single-shot with a 5" barrel and also with a 22" barrel.

He also had some of his (easily verifiable) facts dead-wrong if it was written any time close to the publication date.

The article was on the fiveseven pistol and Ps90 carbine, So I bet the last set are for the Ps90

Reloading Reloading info for the 5.7x28mm


Preliminary test of Vihta Vouri 3n37 powder, which , on paper, also seems a good match for this caliber. I only loaded 9 rounds, 5.8 grains, and used CCI 400 primers, topped with the ubiquitous 35 grain Vmax.

3n37:

1919 mean, 70 es, sd of 25

Instinct tells me this has real promise. The load didn't "feel" hot, and it piled up the brass in the same little area. Primers looked to be what I now consider normal for the CCI brand. I guess my next batch of test cases will be 3n37 with various primers and some slightly beefier doses.

One more thread to go, misc. tests

This is the latest for VV 3n37; CCI 400 primers and 35 gr. Vmax bullets:

All rounds grouped good for this shooter. Rounds cycled normal. Hard extraction marks on case rim. Use homemade brass catcher.

Sulafool, like your charts they are helpful for me. Feel free to use any of my data if you can.

The recoil was a bit stiffer than the factory ammo, and not surprisingly, it was more accurate and more consistent (the SD was 12.76 fps, and the ES was 34.59 fps. nice). The primers were not cratered, but they did show a deep primer strike and evidence of flowing and forming over the bolt face. I'm thinking that the PS90 can take a little more.

Here are the results of my primer test with Blue Dot. I used 7.0 grains and the usual 35 grain Vmax bullets, seated to OAL of 1.45".
