Need help with 45 acp loads

I have tried titegroup as well as w231. The loads shoot fine but I sometimes get blasted with unburnt powder while shooting. My loads are midrange loads that seem to do well on the target but I might get a few per 100 that blast me. Sometimes every thing goes great then other I get frustrated. :banghead:

Load from memory
200gr plated lead from extreme over 5.0-5.2 titgeroup
200gr plated lead from extreme over 5.4 I think w231


I have tried these powders because I would like to have one powder for all my pistols 9mm,.40,.45

For 200 gr Lead I use 4.8gr WST. w/max at 5.1gr. Burns super clean too. For heaver loads I use WSF . Both of these are ball powders and meter fine in most powder dispensers.

from my trial and error findings watch the plated rounds they can vary in diameter from .4505 to .4520 dont know if this effect your gun any but until i get ok with a certain bullet i check weight and size to make sure of the products QC. never can be too careful. be mindful of col in .45acp just a change from 1.253 to 1.232 can effect fps by 50fps or more.

No powder converts completely to gas, they all leave residue the same as most things you burn. If you are feeling this residue after you fire and are shooting a semi auto you are likely getting some bounce back from a nearby object or having it redirected by a muzzle brake or flash hider. From revolvers it often comes from the cylinder gap. If the wind is from the rear you never feel it. Just one of the things you live with as a shooter and one of the reasons you wear a pair of glasses is to keep it out of your eyes.

Yea I always wear my glasses but this is a little different does not do this out of any of my pistols but both of my 45s are doing it, also on my RIA 1911 you can see the unburnt powder after a shooting it.

elwoodm you are right never be to careful I say this to my buddy all the time I might play wit the col a little to see what I can do.

Your experience has not been my experience with W231. I employ 5.5grs of W231 with three bullet weights 200gr, 225gr and 230Gr. Yes the pistols carbon up but I’m not seeing un-burnt powder particles. I use WLP & CCI-LP primers and taper crimp .469" / 472".

Titegroup is the likely cause with light loads.
Win 231/HP38 will burn "sooty" when loaded light, but no unburnt powder.

Yes, I think you are on the right track. When I do load development/powder workup, I do experience having my face blasted with certain powder particles at lower charges and even see unburnt powder left on the pistol. I have shot various 200 gr bullets with 5.0-5.5 gr of W231/HP-38 in various 1911s (including friend's RIA Tactical) mostly without unburnt powder hitting my face so it might be not long enough OAL and/or enough powder charge (longer OAL will allow the bearing surface of the bullet to engage the rifling sooner to build more consistent chamber pressures).


My loads are midrange loads that seem to do well on the target but I might get a few per 100 that blast me.
Since you are having problem with a few instead of all of them, your OAL/powder charge may be on the fringe of generating more consistent chamber pressure. Note that X-Treme 45 caliber bullets (http://xtremebullets.com/plated.htm) come sized either .451" or .452" diameters, so if you are using .451" diameter bullets, you may need to use slightly higher powder charge as more high pressure gas may be leaking around the bullet and decreasing the chamber pressure (especially if your barrel is oversized).

I would first determine the Max OAL (http://www.thehighroad.org/showthread.php?t=506678) and Ideal OAL (http://www.thehighroad.org/showthread.php?p=7717654#post7717654) that will reliably feed/chamber from the magazine. If the problem persists, then I would increase the powder charge.

I know nothing about .40, but I can recommend WST as a super-clean target-strength powder for .45ACP and 9x19.

200 PSWC @ 1.27" 200 PRN @ 1.25" 185 JHP @ 1.20"
4.1 to 4.3 4.1 to 4.3 4.3 to 4.6

124 PRN @ 1.10" 115 PRN @ 1.10"
4.0 to 4.5 4.6 to 4.9

These are already fairly light loads; going below them might necessitate a light recoil spring.

Are you seeing a lot of sooting on the outside of the cases? I found that some powders, like H110, would not build enough pressure with light bullets to seal the case. I'd get grit sent back in my face from my .45 ACP bolt gun and see lots of carbon on the cases - sometimes grains of unburned powder trapped between the cartridge case and chamber wall. Chrono velocities were all over the place which confirmed unreliable burn of the powder. I'm sure a heavier bullet would have helped.

Hmm... W231 is a lot faster than H110 - I had W296 in my mind when I wrote my reply (which is very similar to H110). Don't know what to tell you, then!

rc I like the thought and will remember that.


Navy I am seeing a little soot on the case but I do not think it is abnormal.

I agree. I use a lot of W231 in a lot of different calibers and I never see unburnt powder. I load 5.5gr W231 under ant 200gr or 230gr bullet with good success.

I use Universal Clays in 9, 40 and 45 and have not experienced any residual blow back. I would recommend you try another powder of choice just for the sake of comparison.
