Problems with 10mm Colt

[danny lee mccall]

I am just looking for information. I have a pretty new 10 mm in a what I think is a nice 1911, been shot about 60 to 80 times. I reloaded some with 800x 9.7g 185g bullet. I had one jam up till I shot about 10 of these. now it Jams every shot. no matter what I shoot in it. Winchester target loads to win defender at 1240 vel what could I have possible done to it, I have cleaned it smoothed some burrs off all to no avile

What bullet were you using?

Are you sure it's that new? Magazine springs could be causing the issue.

What's your COL?

You're extractor may need tweaking. What kind of jams are you getting?

I have had failure to eject problem w my Colt delta elite. This was remedied with a new extractor. I bought it used and had no idea of its history so it was no big deal.
Can you detail exactly what is meant by "jam"? Failure to eject - spent case stovepipes keeping the slide from going forward to load the next cartridge? Failure to feed - bullet stuck on ramp or car tridge stuck at an angle? Failure to lock the next round fully into battery and difficult to pull slide back to get the stuck cartridge out? What is it you're having to do to un-jam? Is the jam the same every time it happens?

On 1911 style pistols I've had problems with, the magazines are the culprit the vast majority of the time.

Based on what the OP has written (or at least HOW it's written) this appears to be the first time these particular 185gr bullets have been fired out of this gun (but perhaps I'm wrong). On top of that we don't know what kind of jam is occurring. I recently solved an issue in one of my 10mm guns related to the bullet itself, so I could see this easily being a problem for the OP as well.

I read him as saying that after shooting these rounds, he now encounters jams "no matter what I shoot in it."

I agree we need more information about the jam type to provide meaningful input.

Sounds like something has left residual material somewhere to me. Nose of a bullet hung somewhere, shaved, and now it’s catching more solidly, or something to that effect.

for what it’s worth, when I had a delta, it ate berrys 180 truncated cones and was acceptably accurate. I had issues with some random bullets hanging but once I had the truncated cones I was happy enough to stop experimenting.

another thing to look at is case sizing. If you are using cases fired in the colt then they MUST be full length sized every time. The colt barrels do not support the case head and the cases bulge. That was the thing that made me sell my delta. If it wasn’t supported then I didn’t consider it safe to shoot full power loads and if it’s not capable of full power loads I didn’t see the point of having it in 10mm. That’s a whole mother can of worms though. If factory loads work but reloads don’t, look at your cases and see if they bulge. It’s well documented that it does it, and Colt doesn’t care because they are making money.

I reloaded some with 800x 9.7g 185g bullet.

Hodgdon MAXIMUM is 8.7 gr 800X with 180 gr bullet.
A 15% overload may have bent something.

 

[tarosean]

Agree need more info.

Failure to extract, failure to load, failure to ?????, stovepipes, etc. Etc.

 

[Tinman357]

9.7gn of 800x is quite a bit over maximum. It's very possible that you damaged the gun in question. You didn't mention anything about how the brass looked, so I'm assuming the worst.

1. I strongly recommend that you take this weapon to a gunsmith and have it checked out.

2. Pull down whatever reloads you have and re do them. While it is possible and even safe to work up over max pressure loads, I don't recommend that with 800x. At all. Ever. My experience with 800x is 1/10 gn increase can start showing signs of over pressure. When I see that I back off a half a grain and that's my max load. At 15% over max it's just a matter of time before metal fatigue catches up with you and you have a catastrophic detonation. You could seriously hurt yourself and anyone around you when it decided it's had enough and lets go.

All that said, I'm no expert by a long shot, so I err on the side of caution. Others may have a different opinion. I'm going to assume that you're an experienced loader and you know what you're doing. Be careful out there and I hope you get that pistol shooting again soon.

Their is a thread in gunsmith forum, same OP. Data seems to be all over the place. Loading a Colt hot, bad idea. imo.

Some internet data. A lot HOTTER then Hodgdon data @ 8.7 gr.

From other thread

Kimber long slide target in 10 mm

Not a Colt or 2 guns? https://www.thehighroad.org/index.php?threads/recoil-springs.858590/#post-11282256

 

[Tinman357]

I stand corrected.

 

[ApacheCoTodd]

What bullet were you using
What kind of jams are you getting?

Yup, this is all an exercise in hypotheticals until the "jam" is effectively described.

I got it going shoots great thank you

I am thinking about buying a rem R-11 long slide in 10 mm, do you know if it has a fully supported barrel? . the Kimber 10 mm does. I just love these long slides. and want another. thank you.

The delta is the only 10mm I have had. I remember when I had my issues that other complaints and comparisons existed, and at least one showed a r11 and I believe that it was fully supported, but that was a long time ago and that’s me pulling from memory.
