Series 70 Gold Cup Problem.

Post by USSR on 9/4/2017, 11:29 am

Thought I would ask you about the ejection problem I am having with my 1911 (Now I remember why I am a revolver guy).   No matter what reloaded ammo I am using, I get some failures to eject.   Some are verticle stovepipes such as this: http://cdn0.thetruthaboutguns.com/wp-content/uploads/2014/02/Vertical-stovepipe-courtesy-modernserviceweapons.com_.jpg and some are horizontal similar to this: http://www.thefirearmblog.com/blog/wp-content/uploads/2014/02/20130110-IMG_1190-600x450.jpg
Can happen at anytime when shooting a magazine (Chip McCormick) full of ammo.   Did the extractor test of firing ammo without the magazine in, and most all of the empties went out at about 5 o'clock.   Any ideas as to what is going on?   I know it is difficult to diagnose thru a thread, but could anyone suggest a gunsmith familiar with 1911's that I could send it to?  I live in upstate NY (Finger Lakes Region).   Thanks in advance for your reply.

I would play with extractor tension, start by increasing it.

Not something I am going to mess with.   Any suggestion for a good 1911 gunsmith that can go over the Gold Cup and make everything right?

If you take the slide off the gun and slide the barrel forward and slip a dummy round  under the extractor does it hold it in place against the breach face?

I've got a Wolff 14# recoil coming from Brownell's.   Once it arrives I will take it apart and check it out while installing the spring.   Probably should have been more clear that I am really looking for a good 1911 smith to have go over the gun from top to bottom.

I once had a series 80 series gold cup that had the vertical stove pipe problem. The extractor tube would get full of crud which caused the extractor to get pushed out a little. I tried to keep that tube clean but the problem didn't really go away.  Second fix was to change the ejector to an extended type. Gun never failed after that.

You mentioned reloads. Does it cycle factory ammunition ok? I'm guessing it's too heavy of a recoil spring that is IF your reloads are lighter target loads and IF you're using a 16# factory spring. What load are you using? A good 1911 smith would be Jon here on the forums, KC's Kustom Creations, or some other names that people here tend use on a regular basis. Ask around.

Don't know - I've never shot factory ammo in it.   You may be on to something with the recoil spring (Yes, it's 16#).   I have a 14# spring on the way from Brownell's.   My typical load is a Lyman 452-460 SWC with 4.2gr of Bullseye.   I will look into KC's Kustom Creations.   Thanks.

On my first Les Baer I chased my tail forever with the occasional stove pipe and I kept going down in spring poundage. Ended up just needing more tension on the extractor.

You might as well get to learning the basics of 1911 maintenance and repair. If you plan on shooting much it will make life easier. I'm not lucky enough to have a good pistolsmith locally.

When it trapped brass was another round stripped from the magazine and attempting to enter the chamber when it happened with rounds still in the magazine? Did it ever happen on the last shot and magazine empty?

Yes, it was attempting to feed a new round out of the magazine and into the chamber with the spent shell casing trapped on the extractor.   Don't remember if it ever happened on the last round from the magazine.

This issue is common with handloaded target ammunition. It comes from insufficient slide velocity imparted from the fired round. The first thing to do is to field strip it and ensure that it is clean and lubed using high quality firearm specific lube [no WD-40, no Rem-Oil, etc.]. Then, using an accurate load that is proven in your pistol, try a 14 pound recoil spring and if that doesn't work, try a 12 pound spring. Most ammo issues are solved this way. 

If you decide to got back to hardball loads, return the 16 pound spring to the pistol.

If this does not work, then start examining the extractor, slide to frame fit, etc.

You may also want to double check that your loads are indeed 4.2g...I had some issues a while back and found out that while I thought I was loading the right grains, the scale was not calibrated properly and loaded light.  YMMV

Cleaning and lubricating it helped, but I have pretty much traced it to the extractor.   Rather than just replace the extractor, I am going whole hog and having a Kart Xact barrel and bushing, EGW Oversize Firing Pin Stop, and Wilson Combat Extractor put in.   Something I've wanted to do for some time now.   Thanks.

I thought you had a guy and that good gunsmiths are where you find them and all that??

Did you email Ed Hall (upstate NY) or Tom Ginovsky? TEG2658 is in the Buffalo area I believe. Been shooting bullseye over 30 years in that area and should know a gunsmith.

I do have a gunsmith, a local guy who has worked on Bullseye guns before.   So, I am all set.
