9x23 & .38 Super loads in EAA Witness

OK, I took my pistols out to the range today and collected some preliminary data.
Each test was only 5 rounds (just enough to have my chrono calculate the Standard Deviation -- for what that's worth).

As a baseline I ran 5 rounds of Winchester White Box 125 gr. JSP through each gun.

Load: 9x23 Factory WWB
Pistol: EAA Witness (steel)
Barrel length: 4.5"
MV: 1431
SD: 19
ME: 568.3
PF: 179


Load: 9x23 Factory WWB
Pistol: EAA Witness Compact (steel)
Barrel length: 3.6" (Mag-Na-Ported)
MV: 1347
SD: 17
ME: 503.6
PF: 168

So you can see that the WWB stuff is pretty good ammo and makes Major PF for most organisations. You can also see that the shorter barrel and porting costs 84 fps or about 6%.


Next are my test loads. Both were shot out of the 4.5" barrel.

Cartridge: 9x23
Powder: 9.8 gr HS-6
Bullet: 125 gr. Cu-plated lead.
Primer: SR
Case Win.
MV: 1363
SD: 23
ME: 515.6
PF: 170


Cartridge: .38 Super
Powder: 8.5 gr. HS-6
Bullet: 125 gr Cu-plated lead
Primer: SP
Cases: Mixed
MV: 1167
SD:27
ME: 378
PF: 146


Both cartridges functioned well in both Witnesses with no problems at all. Recovered brass looks fine. Both pistols have their original .38 Super barrels. I have installed shock buffers from Buffer Technologies in both guns.

I guess it's time to go to the next step.

OK, I just completed the "next step" at the range today.

Chronograph was about 15-20 feet from the muzzle in all cases.

Cartridge: 9x23
Pistol: EAA Witness (steel frame) .38 Super
Barrel length: 4.5"
Powder charge: 10.5 gr. HS-6
Bullet: 125 gr. Copper-plated lead truncated cone.
Primer: Small Rifle
Case: Winchester
MV:1605 fps
SD:7
ME:715
PF:201

Yes, I truly consider this a MAXIMUM load. It works in my pistol. It may not work in yours. Start lower and work up slowly. Primers are rather flattened, but the cases still fit back into the chamber after recovery. No bulges or stress lines.

This load truly gives .357 Magnum performance in an auto pistol that carries 17 rounds in the magazine!

I tried a hotter load, but it was too hot. The first round fired fine but would not extract. I had to drive the case out of the chamber with a rod. The extractor tried to do its job; there was an extractor-sized chunk of brass yanked right out of the rim. Not tellin' how much powder that was. Other than the gouged rim, the brass looked fine -- I'm really appreciating that Winchester 9x23 brass!




I also worked up another .38 Super load while I was at it. I have a fair supply of Winchester 231 powder, so I tried it.

Cartridge: .38 Super Auto.
Pistol: EAA Witness (steel frame) .38 Super
Barrel length: 4.5"
Powder charge: 6.0 gr. Winchester 231
Bullet: 125 gr. Copper-plated truncated cone
Primer: Small Pistol (Magnum)
Case: Mixed
MV:1170
ME:380
SD:38
PF:146

The high SD is probably due to the mixed cases. This is a pretty good .38 Super load if you have a bunch of 231 sitting around. I wouldn't try to push 231 to any higher power in the .38 Super though. Primers were flattened a bit. Cases look like they'll have a nice long life.

Next step will have to be testing the 9x23 load out of a 3.6" ported barrel...

Wrong - it EXCEEDS factory .357 Magnum performance in that barrel length.

Unless you're referring to handloaded .357s maybe. ;>)

Well, I was giving the .357 the benefit of the doubt. I am sure that handloaded .357's can exceed what I have gotten from my 9x23, (heck, I have .38-40 loads that exceed it) but I am happy with it.

If you're getting an honest 1600 fps with a 125gr bullet out of a 4.5" barrel and no excessive wear on the gun, I am impressed!

Well, that's what my chrono says. I haven't put all that many rounds through the gun --- I suppose time will tell.
