I found when I did not have enough powder, it seemed to burn dirty. when I upped it a couple of tenths, for my load, that it burned cleaner and obviously was a bit faster. perhaps you need to increase the amount.

I used the same load under Berry's with a 1.230" COL. 5.3gr was cleaner, 5.4gr was cleaner still.

the OAL they used in the hodgdon loadcenter for 230gr LRN was 1.20, you are loading longer which will drop pressure....don't know how sensitive hp38 is to volume changes, but maybe that's the reason you are getting inefficient burn.

Little more spring weight to hold case in chamber a wee bit longer for more to go out front before slide start to move and vent the rear...

Shortened it to 1.20 tonight, and I'll tighten the crimp just a wee bit as well.
I'll see how it works. |

pepe-lepew is correct. Proper neck tension is what is used to hold the bullet in place not crimp.
If you don't like the blow back switch to a faster burning powder. I say it's a non issue. Shoot it and let the tumbler media clean em up. |

Not sure what you mean by powder blow back. I get torching on the side of my cases and I'm using fast powder. Tried upping the charge and I still get it. No ill effects but produces quite embarrassing spent brass.

OP,
Are you asking about sooty cases or unburned powder blowing back in your face ? I thought you meant unburned powder mess....which usually means insufficient crimp |

HP-38/WW-231 have always sent specs of powder to the rear landing on my forearms and shooting glasses when fired from a 1911. I use 5.2 grains with H&G #68 200 grain semi-wadcutters. Velocity is 800 fps over a chronograph. Many others report this as well. It's normal when using this powder.

Whenever I get powder blowback, the first thing I try is lowering the charge.
In for answer ETA My reasoning being it's not all getting expended thus I'm using more than necessary. HP-38 is my main powder. |

I ran 45acp w-231/HP-38 for years in IPSC
Set your factory crimp die to about .470 Several years ago a nationally known IPSC shooter recommended 3.8gr CLAYS with a 230gr. This load is clean, accurate, makes major power factor, is affordable, and very low muzzle flash I haven't used 231 for 45acp in years, but a firmer crimp can help with unburned powder |

Final update. I changed my seating depth to 1.20, upped the charge to about 5.3/5.4, and that cut the blow back down by 90%. Still a little bit, but its more than bearable now.
Not seeing any pressure signs, so I think I'm in business. Thanks guys. |

I use 4gr of Bullseye under 45 lead bullets, I get unburnt powder all the time. On FMJ loads that are around 5gr I do not see this. In low pressure rounds you will not get an efficient powder burn. Upping the charge may work, but the real issue is the pressure. Some powder burns well at low-high pressure, others only burn well at near full power loads.
