Hi all, so I was at the range this morning to test out my new 45 with some reloads. I have never reloaded a pistol caliber and only brought a few rounds for testing purposes. Accuracy was good and had no FTE or FTF but did notice powder or something blowing back could feel it pepper my hand and also face a few times glad I had on my glasses!

was using berrys plated 230gr rn
remington new brass
cci 150
titegroup 4.7gr
C.O.L 1.230

I am wondering if it's an over crimp problem or under crimp problem or does it have something to do with the overall length? Each empty case was filthy on one side only so I assume gas/powder escaping back but not sure why. This was my first time shooting this pistol so maybe I should break down and buy a box of commercial to see how it shoots?

Thanks guys.
 
Interesting, ihave this happen all the time with my taurus too! I figured it was the powder i was using, 700X, but you say it is happening with titegroup, and i have never used it. But seeing we have the same bullets, maybe what you suggest is true. hmmm.....
I also thought it was maybe chunks of walnut media that was left in the cases?
 
If you are getting sprayed with a 1911,and your primers are not pierced,odds are it's oil from the slide rails.

Switch to grease.

Titegroup is somewhat notorious for sooting up cases, but that shouldn't translate into debris flying back.
 
Just checked all the primers and none were pierced. I use grease for the slide already hmmm. The reason I suspect there is excess gas coming back is EVERY case was filthy from front to back on the outside of the case and only down one side.
 
I had this problem once with a chamber that was oversized. The case was not able to expand & fill the chamber when fired allowing some gas to come back.
The fired cases has a lot of soot on them and some particles came backwards and sideways out of the ejector port.
 
Very possible. I'm thinking about these loads and maybe the load chosen isn't sufficient to get consistent and complete burning of the powder in this firearm.
Brass that gets sooty usually hasn't expanded enough to seal the chamber's wall from escaping gases.
Or could it be an oversize chamber?
PP.
 
colinjw, that sounds right I guess I need to bring the pistol to a gunsmith? How do I measure chamber and if it is oversized what do I do? I can feel myself sinking into the deep end!

PerversPépère, are you suggesting that I go up a bit on the charge? I guess I could try going up in increments to 5gr and see if it makes a difference...

Thanks for the replys gentlemen, this is how I speed up my learning curve...

Titegroup is known for staining cases, even 9mm running hotter. It's possible the OP's problems are related to low pressure, but I wouldn't take the presence of soot to be an absolute sign.

I shot .45 for 10+ years using lead, jacketed, and electroplated bullets, and using a wide variety of powders. I have seen filthy chambers and muzzles. I've seen powders almost sparking coming out the muzzle (700X and cast lead).

I've never had debris blown back.

Like he said x2 I suggested the dies as when I first tried plated I was shaving plating during loading and getting some plating debris
 
Me I would buy a box of factory rounds and see if the problem continues. The seal from gas expansion is suppose to prevent blowback. Have you ever seen a high-speed film of a 1911 in action. The slide starts moving pretty quick after the bullet leaves the barrel. If there isn't enough pressure for a seal, there would be blowback.
Check the reloading manual for titegroup and go 10% under max loads and work your way down till the blowback reoccurs. Then go back up till your satisfied.

You may be onto something. I noticed last loading i did of some 10mm, it was zero degrees or so where i was loading, and i noticed upon set up that i was cracking the plating off of them. So i backed off the crimp, and it went away.
Maybe this is what was up before, but it was not cracking off completely.
 
Stuff flying around when handguns are fired isn't unusual. Could be a bit of unburned powder, oil or grease, if there's too much. Some powders just burn dirty too.
"...go up a bit on the charge..." 4.7 of Titegroup is one grain under the max load of 4.8for a 230 cast bullet with an OAL of 1.200". Plated bullets use cast data, going over max isn't a good idea. You really should work up the load from the starting load, not just pick one. And a light taper crimp only.
"...was shaving plating during loading..." Not enough flaring of the case mouth.
