Looks great!! I haven’t tried heavier then 147 yet. Those green color look very nice!!

I just ordered the 358-158 mold to try a little heavier slug.

The green ones are a grooveless 156gn RNFP. it has a Crimp groove only and it is in the perfect location for 357Sig heavy crimping.

The gun and 357Sig is used to play IPSC here in Australia. We can't use 40 or 45cal, So 357Sig is Major power factor for STD Div and Classic Div,
Here is a 185gn FP i'm playing with for 357Sig.

Jeeez that doesn't leave a lot of space in the brass.

What are you guys seating your 125’s in the 9mm to?

[cwlongshot]

I just seated two dummies at crimp groove. I haven’t had it in or cycled thru any gun yet. Any measurement I would recite wouldnt mean much.

That's awesome! Do you mind sharing your load data? There isn't very much case capacity remaining there.

Anyone try this in a 357SIG?

Lights out with Sig 1911 nightmare & G22 conversion barrel using stock 357Sig & converted 40SW brass. Be mindful of your crimp as case-mouth tension is paramount.

These are fired in STI Edge 2011 Std Div guns. 4.4gn AP-70 ( Hodgdon universal to you northerners) seated to 31mm OAL
In the Glock 35 357Sig, 4.2gn AP-70 seated to 1.155". Both loads use heavy crimp. All loaded in re-sized 40S&W brass.
We very rarely use actual 357Sig brass down here in Australia, as 40 brass is free from the police. Primers are Magtech small pistol.
The 4.4gn load gives 174 power factor.

I really like that Green!!

Im gonna see what I can come up with mixing colors!!

My 358-158 mold came in today and we are gonna be socked down with two snow storms forcast! So Im gonna cast some in the garage again!!

The green is called Kryptonite Green HITEK coating.
Donnie at Highperformance coatings has it.

I used that mold this weekend and ITS FIXED!! I was pretty ginger with it, but I cast a couople hundred more bullets and its working just fine!!

I also cast a couple hundred with the 358-158 Mold. it has some spure plate problems I have never seen... It dosent flow well. At first I thought dirty contaminated. I blasted it with parts cleaner spray and started over... not much better... few cycles later II tried again this time with a stiff nylon bristle brush for cleaning molds... Not really any better... I de burred the face and top with a file, no Burs detected.. I stoned the chamfers and cleaned again... still cannot really say its any better. But It casts a nice bullet its just hard to fill???

Lastly I tired to match up that HYTEC color Kryptonite Green...

I think I did pretty good too!! 2 parts Kawi Green, 1 sm part Mirror BLK one part Copper metallic. All mixed well and coated...







Here it is in extreme close up, out in the afternoon sunlight.

I am seating the Lee 358-125-RF to a OAL of 1.025.
I size to .357 using a Lyman lubrisizer and NRA 50-50 lube from White Label.
At this length it runs perfectly in all my 9mm handguns, including my Range Officer which I didn't really expect since it can be picky about OAL.
I shot some of them today and got a 2.5inch group at 10 yards for 25 rounds with my Taurus PT92.
I arrived at this OAL by looking at the side of the boolit after sizing. You can see where the sizer stops sizing the boolit and I seat that spot even with the case mouth.

I get it ... bumping an oldie but goodie. Only us SIG 357 fans can truly appreciate this thread. Finally stumbled upon this same 6 holer ... really looking forward to giving these a try.

Still enjoying my lil 357's. Picked up a G24 & a 6" KKM barrel for it just to have a long slide 357 Sig!

Its a coyote killin machine!!
