New to reloading question. - The Firearms Forum

Hi, I have finally taken the plunge and started to reload. On my first batch of ammo I load some 325 wsm with Barnes Triple X and per tech help from Barnes I loaded 66 gr., 67 gr. and 68 gr. They seemed to have shot fine and the cases appear to be fine except for there is a small dent in the shoulder of each of the casing now. It was not there before I fired these. The casing are once through thie rifle. The rifle for what it is worth is a Kimber Montana 8400.
Is there a problem with the casings or the chamber of my rifle. Is this something to be concerned about???

Thanks,

Doug

If its in the same spot every time I'd suspect an extraction dent, but by all means inspect the chamber. You can always shoot a few as singles with the case head stamps oriented the same way and see if the dents show up in the same place. >MW

Hi, Thanks for the reply. I will go out and try what you have suggested and see what happens. What do you mean by an extraction dent. Do you mean it is catching on the chamber or around the receiver area?

Thanks,

Doug

dents in prefired cases will go away after firing, so if you have dents in your cases after firing, you can be sure its not from the reloading process.

I am assuming you inspected the brass before reloading and there were no dents. Further, I am assuming you did not "full length size" the new brass (if you did, and got lube on the shoulder, it could have caused your dents).

If the above holds true, I doubt that the dents are a result of your reloading. As brass expands when fired it takes on the shape of the chamber - which may have a burr causing the dent. Fire a couple of factory rounds and see if you get the same results. I'm guess'n you will. If I am correct, send the gun back to Kimber with a couple of spent rounds and they will correct the problem. While what you describe is likely "no big deal" the dents may cause your brass to fail before you reload same as many times as you would like.
