Another thought. Are you seating and crimping in separate steps? If not, give it a try.

Will just a sized case pass the plunk test?

Had a similar problem with a Sig 1911. From the factory no throat or lead in barrel. Made loading SWC very difficult and rounds would not pass plunk test.
Sent barrel to gunsmith to have a throat cut in barrel and problem disappeared. The Lee FCD will also work,but make sure you are not swaging down bullet diameter. |

Post 5, 15 and 21. No I am not crimping with a separate die, step. Then I never had a problem where I found it necessary before this. |

Tranders makes a good point. Throating reamers for .45 Auto were made for target shooters to funnel lead SWC's a little better into the rifling, but in the day of practical shooting they seem to have been forgotten. It can still be a good thing to try. But a light turn with a standard chamber reamer would be where I would start.

Unclenick, ran a brush thru the chamber again this morning and then the Bore Snake followed by doubled up clean patches. Patches came out a little dirty but not what I would call dirty. They looked like I wiped them down with Hopp's oil. Then turned the seating die down one more 1/8 turn and everything is dropping nicely now.
The guy I bought this gun from told me that it hasn't been shot in quite a while, the reason he was selling it. So I'm beginning to think that a combination of a number of things brought all this about. 1. The gun barrel being tight and perhaps a little dirty with varnished up oil 2. The dies are new also. I don't think I have 250 rounds loaded on them yet. And yes they were cleaned before I started using them. 3. Sometimes one just needs to back up and start over from the beginning. |

I had the same sort of symptoms with 38 Special. It was suggested to me that the bullets were canted and that I should try the Hornady seater with sliding sleeve to align the bullets. Cleared it right up. So far though I only seat with the Hornady and still use a cowboy die to roll crimp the .358 bullet. I also used a tighter sizing die but am not sure of its effect.

Latest update for all.
Finally got to the range and was able to fire the rounds in both guns. All rounds fed, cycled and went boom in the Witness. There was one set of loads that wouldn't cycle reliably in the XD though they did in the Witness. In total we shot 4 loads using the XRTEME 200gr RN and two powders, 2 loads each of the Berry's 185gr Flat point and 2 loads each of the 200gr Berry's Flat Point. Again the powder tests were done using AA#5 and Ramshot Silhouette. After I use up this jar of AA#5 I believe I'm going to try some AA#2 for the 45, 9mm and my 380. The one thing I've learned with these 45 loads in these two guns is that they need to be loaded much shorter than suggested so the next loads I am also going to try and reduce the charge slightly. Thanks for following along and for all the suggestions. |

Be careful as you go to faster powders that seating too deeply can raise pressure excessively. It depends on whether or not the bullet was unseated and pushed into the throat by the primer before the powder pressure built up much.
I have found best accuracy with lead or other soft bullets and the lowest metal fouling happens when you seat them to jam the throat slightly, gauged as shown below. However, if they won't feed with that gaging, they are not being useful. Getting a reliability package from a reputable gunsmith is another way to go for feed issues.

I was just chatting with a member on another forum only to find out he is also a moderator on one of the CZ forums to which he has told me that this is a common occurrence with CZ and Tanfoglio pistols because they are notorious for having tight chambers and short throats. He is telling me that with his guns he has to seat Flat Point and SWC so that the shoulder is barely exposed.
I also mentioned shortening the OAL AND reducing the powder charge at the same time to allow for the shorter case capacity. So when I make the change to the faster powder I will also take into consideration the length and reduce the starting charge as well. |

I had to respond again after re-reading the replies. Not once unless I missed it has the OP told us what the OAL is on his rounds??????

Don P, apologies on the oversight.
With the RN bullet the original length was 1.270" and am now down to 1.260" and all is well now. Also because of this shortening I also reduced the powder charge from 8.2gr of AA#5 down to 7.9gr and these are firing and completely cycling both of these guns. The Flat Point bullets are down to 1.185" I also just loaded up another 120 of these RN using the odds n ends brass I had after sorting headstamps. While doing this I came upon 4 headstamps that would not seat in the Witness and they were; MAXXtech, GECO, A 15 and one other that I don't recall other than after trying 2 I threw them in the recycle can. Though they would not seat in the Witness they did drop right into the XD and dropped right out when turned over. Also measuring these after loading they are right on the margin of being over sized in diameter. |
