Question about Kahr K40 spent brass

[jdg30]

I have been saving all my used brass for quite awhile now with the intent of getting into reloading, but I have not actually purchased the equipment yet. My first gun I ever purchased was a Kahr K40. It is a great gun, very reliable and really accurate. The one downside to it is what it does to the brass when it ejects it after firing. Most of the cases have a "D" shape to the case mouth after they are ejected. They usually have a flat side to the case mouth and have an obvious scratch on the side of the case wall. When I see the cases come out like that it makes me not want to shoot the gun because I feel like the cases are damaged and am therefore wasting good brass because of the case deformity.

My question is if these cases are too damaged to reload. Will the resizer die take care of the problem or is the "D" shape significantly shortening the life of the brass for reloading? I would like to keep shooting the gun if the brass is still good to reload, but if it is seriously damaging the brass then I might consider using only steel cased ammo to throw away or selling the gun. I compare the brass from the K40 to that fired out of my Glock with a KKM barrel. The KKM barrel brass comes out in very good condition. The cases have no bulge in them like from a stock Glock .40 barrel, and the case mouth is usually very round.

I would appreciate any feedback from those who are experienced in the same problem with "D" shaped or distorted spent casings who can tell me how it affects the brass life for reloading. Thanks

Get yourself something like this http://www.fine-tools.com/st306505.jpg and cut it to a useable length, it will help straighten the "ding", then resize like normal.

The case mouths will straighten out when it passes through the sizing die. I've seen some pretty flat cases go through my dies with no problems.

What's worse is the lower case body bulges that the Glock chambers leave.

The die should smooth out the case.
