9mm 124gr w231

Recommended Posts

i read on youtube where someone was shooting a semi 9mm pistol, he loaded 5.0 grs of w231 with a 124gr coated round nose, in order to make this load chamber in my wife's walthers PPQ i had to load them at 1.050 and i see this may be on the hot side especially at this length. i only loaded 50, should i pull them and drop the chg to 4.0grs

4.2-4.4 is a good range for W231 with 124's. But as always work up to this range.

Seems like a load from "someone" on youtube should be taken with a grain of salt. I wonder about the wisdom of using that particular load data source when there are tons of reputable sources on the internet and in book form reloading manuals.

Best of luck on your "experiment". Hope your wife's gun enjoys the test...

Good call Chet.

 

I run 124 gr coated with Win 231 and 5.0 seems WAY hot...to me.

 

For my Glock 14 I'm right at 4.0 gr, and I'm at 4.4 for my 9mm carbine, so I'd never go anywhere near 5.0.

 

Doesn't mean someone can't safely go there, but it's too hot for my comfort...

 4.3 of HP-38 (same as W231) is the sweet spot for me, with 124-125 gr. coated bullets,  both RN and TC.

An OAL of 1.130" or as close to that length as possible for RN, and R-P cases works.

😀

I load 4.1-4.2 Gr win231 @ 1.102-1.104 OAL for my Shadow 2. This is for 124 Gr TCFP @ 128-132 pf.

 

You need to have a chrono to test your loads. Check also Lyman’s manual instead of relying on someone’s load on YouTube,

Just finished this exact type of test.  Based on a number of loading manuals, both new and old, 5.0 of 231 seemed midrange with a 115 FMJ bullet.  But I got primer flow in my Kimber 1911 using Winchester small pistol primers.  Pulling the bullets on your 5.0 load seems like a good idea.

I would have loaded 10 ea @ 4.2, 4.4, 4.6 and 4.8 then tried the 5.0 if the 4.8's were good.

I also would have looked at the online data that said 4.4 was the max charge and assumed I should stay under that if I wasn't going to work up the load. 😬

I shoot the same range with 125, 135 and now 105 and 96gr. All coated mostly in a revo but they will all run an auto. (although the 96gr loads aren't reliable.) The 105gr @ 3.4 is really soft for SC etc.

We will all sleep better tonight, bro! LOL

Just want to throw in that I've loaded 4.9-5.0gr under a 115 Xtreme plated. This was a moderate load, in the same ballpark as most factory ammo.

 

With a 124gr bullet you'd be asking for trouble at 5.0gr. Use reliable sources. Youtube is not a source. In fact internet forums aren't a great source. But at least if you can find many data points from various sources all in the same ballpark you can make assumptions. Reloading manuals and powder manufacturer websites are pretty good sources. If you can't confirm a load in a manual or manufacturer's website, probably a good idea to stay clear.

only way to know  for sure is to  chrono.  its a good investment if you reload .  my bet is 5.0 231 124 coated  out of a 4" gun will make about 1125  fps. also to alleviate the short oal on the PPQ chose a bullet with a different shape.

I run 4.1 grains of 231 under a 125 grain blue bullet out of my Walther Q5. OAL 1.125. Last time I chronoed it ranged from 129.25 to 132.6 PF.
