I'm not sure whether to post this on the Auto Pistols Forum or here, since I know cartridge experts here who shoot the caliber will see it, but here goes....

I have a Kimber Target II in 38 Super. It has no issues extracting 38 Super or (when I fit the second barrel) 9x23 Winchester. Same stock Kimber extractor does fine with my mid-level reloads.

However, some of my 38 Super brass is range pickup and happens to be 38 Super Comp. It seems that about 90% of those Super Comp cases fail to extract. If I experience an FTE, it's always a Super Comp brass.... which will fall out of the chamber when the action is opened and the magazine lowered.

I know all 3 brass have different rim diameters, but I was under the impression that the Super Comp rim diameter was between 38 Super and 9x23 Win. So why do I have these issues?

The Kimber is less than 1 year old and has maybe 3000 rounds through it.

I am no expert here, but Jim Watson told me through PM's when I asked him about the differences that some guns will run either brass, and some won't. He said some can have the extractor tweaked and then they will run both, but maybe not. IIRC anyway.

Maybe he will post soon. He was very helpful to me when I got my .38 Super and had questions.

I hand fed both types through my Springfield .38 Super and the Super Comp was smooth as silk, so I bought Super Comp brass. It also fed regular .38 Super and I have fired some without issues. I bought the gun used. It was an older competition gun. It may have been set up so it could run either. I don't know.

I also have a Colt Series 80 .38 Super, and it runs fine on Super Comp brass.

Wish I could be more helpful.

I am looking to buy a gun just like yours. There is a 6 month backlog on the 38 super Target II.
