KIMBER offers more barrel chamber support in 10mm than any other manufactuer?

[Yondering]

So you're refering to headspace?

Sorta...

I just mean if the chamber is reamed deep, then the amount of the head that is unsupported could vary a few thousandths when it is in firing position from when it is dropped in.  I can take a barrel that appears to have poor support and make it look better by reaming the chamber a little deeper.  It won't be better, but it will look better.

I don't know a good way to account for this.

Yes, what you're describing is headspace.

Looking at EdMc's picture above, the Kimber barrel looks like it has deeper headspace than the colt. The barrel hood looks like it's sticking up past the brass on the Kimber.

I should mention, the Kimber/Colt photo is one I pulled off the internet. I can't say for sure it's a Kimber barrel as I don't own one. I do own a Delta and the barrel looks like the one shown.

I took 10 pictures and these are the best pics I could get with a Nikon Coolpix (useless camera).

Have you tried the "Macro" setting on the camera?  This allows the camera to focus on very close objects.  If you can't find that feature (I don't know of a model that doesn't have it), or can't figure it out, try more distance and use the zoom to get it to focus the size you want.  The Nikon cameras are usually very good, even the less expensive/featured models.  The only complaints with the Nikons that I've heard of is they are "less oversimplified", compared the Kodak and Cannon cameras.

"less oversimplified"

LOL. I'll have to remember that.........apt description of the Cannon model we.... I mean... my wife uses.

its not useless. I can see the handgun safety manual perfectly. Next time make sure the camera is focused on the subject matter.

Problem is it WAS focused on the barrel , you press down on the button and it auto focuses with the IR, the IR was on the barrel,  USELESS , But I will try the macro setting.

Thanks,

The distance to the manual is the min distance that the auto focus can work. The macro setting is for the even closer focal range. Or, something like that. Our Cannon says to use the macro on anything closer than six inches.

If the camera allows you to switch to SPOT focusing, that should do the trick for ya.  It's not the only way to skin that cat, as others mentioned you can also switch it MACRO mode which should allow you to focus up to within about an inch or so (3 cm for my camera) of the camera lens.  Or as has been mentioned, take a picture from further back which will allow everything to be in focus (2 things;  in this case set your camera to it's max megapixel setting and crop it later if you care).

Also, to get the clearest (least graininess) pictures possible, if your camera allows you the option(s), set it to take pictures at any ISO under 200.  This will in many cases force a longer shutter time, even to the extent a tripod would be required some of the time, but only rarely in good lighting.  For example, with my camera it is very rare for me not to have my camera set at an ISO of 80.

The IR light does not tell the camera what to focus on, it simply illuminates an area that lacks enough lighting to focus normally, therefore you can take crystal clear pictures with the flash in otherwise complete darkness.  On my camera you can turn the IR light off altogether.  I don't know if your camera allows that or not.

now that we have figured out his camera settings ( )  here is the chamber support offered by my Fusion CCO in 10mm. 

[EdMc]

Looks like a Delta barrel....?

Not so fast you have not sean my next set of pics.

i believe they use Storm Lake

Just to be clear;  You are saying the pic you posted is a barrel from a Fusion CCO, and NOT from a Colt Delta Elite?

I ask for double clarification because, like EdMc brought up, that pic you posted is the spittin image of a Colt Delta Elite barrel.  I was under the impression that the Fusion lineup in 10mm Auto had halfway decent chamber support at a minimum.  Your pic would suggest as poor as poor gets in terms of chamber support.  So if your pic really is of a Fusion barrel, clearly they offer entirely different amounts of barrel chamber support depending on the model firearm platform ordered from them.

Storm Lake may very well produce the barrels for them but that doesn't answer the question.  For that matter, for all I know, Storm Lake may produce the barrels for the Delta Elite to Colt too.   

[Deadguy]

Redline, yep, that is the barrel from the 10mm CCO I got from Fusion. Unmolested and in the condition I received it in from Fusion. I requested this type of barrel. It shoots the UA 180 grain Gold Dot DE loads, Scottsdale 180 grain TMJ, Double Tap 180/1305fps loads (Intercooler tested a few of those same loads for me) all with no issues. Only problem was the one round of PPU that I (and others) feel was a double charge.

The chamber may have been cut back and the mouth opened up for reliability in feeding in the 10mm CCO platform. It seems the Delta Elite is the only other 10mm 1911 using this barrel setup, and, coincidentally, has a similar lack of support. The longer cartridge, with the lack of a ramped barrel, may require this type of chamber to feed reliably. Just a theory, of course.

[EdMc]

I think you're right, reliability being the reason. Like many things, compromises are made for what is thought most important as with production costs etc.
