Sig V Crown 9mm Load Data

[Hondo Kid]

I just picked up 200 rounds of Sig V-Crown 9mm .355 124gr JHP bullets. The only powder I have is Accurate #5 and Win 231 (HP-38). Does anyone have load data for these powders. I have searched and cannot find anything. The Lee reloading manual I have has:
124 gr Jacketed with Acc #5 with a start of 5.3with a OAL of 1.15
124 gr Copper Plated with Acc #5 with a start of 4.9OAL1.06
The Western guide shows:
125 gr JHP Sierra at a start of 4.6 with an OAL 1.035

Can someone give me what has been working for them with the Accurate #5 or HP-38 / Win 231?

Go to Hodgdonreloading.com and plug in your info. The bullets for Sig are made by Sierra Bullets.

Exactly what I was hoping to find. Thanks for the info. I am a newbie and I have learned to rely on all of you guys to already have gone thru some of these issues and your input greatly reduces me having to "reinvent the wheel" so to say. I have learned that COAL varies by gun and magazine. I have a Walther PK-380 that plunked OK but the COAL was a hair long and I had sporadic binding on one of my mags. Adjusted the CAOL by a hair and runs great now.

Manuals help out greatly, and are a good investment.
Hodgdon does an annual update in magazine form.
If you go to Alliant's website, you can order a free annual paper version from them. Otherwise it's on their website.
Western Powder, owned by Hodgdon now, has their data free online.
As does Ramshot, Vithavouri, Barnes.
Hornady just released their hard copy, and is a good manual. Ditto Sierra.

FYI - I sent an email to Sierra and got an immediate response. Their recommendations is:

Winchester 231 - min 4.4 to max 4.8
HP-38 - min 4.4 to max 4.8
Accurate #5 - min 4.9 to max 5.8
COAL - 1.090

Great customer assistance !!! - thanks to Mitch Demand / Ballistic Technician / Sierra
