Hi,

I am relatively new to reloading, I have done the process a bit and had a great instructor who really knew what he was doing, the problem is its been a while since I have done any reloading at all and now, I have ran into a snag. I am getting a ring around the cases when using my sizing dies. One is a FL .308 RCBS die, the other a 6.5x284 Forrest neck sizing die. I am not sure what I am doing wrong here, at first I thought it was something in the die of the 308, like an unfinished edge or something..... but then I tried the 6.5 die, and the same ring is appearing. You can feel this line with your fingernail, its is a very light score. The 308 had some tightness coming out of the die (more than I think there should be), the 6.5 had barely any resistance at all, I am a little baffled at this and any help would be greatly appreciated.

I think you will find that is caused when you are chamferring your case necks after triming. Mine does the same thing. Are you using a Lee chamfer tool?

This is what I suspect as well, happens to me all the time, I have not seen any safety concerns or decrease in performance and case life cause of it.
 
Probably something in your case prep, I don't think the die is causing this.

Lee chamfer tool did that to me, so I trashed it and bought a proper chamfer and debur tool.
I got sick of doing it by hand so I bought a hornady case prep trio, works fine.
 
I'm interested to know how that can cause those rings. I chamfer after trimming and never get a ring.

I am using the Lee tool..... I didn't realize that.... totally makes sense, not in the die at all....damn tooling marks. haha. I will try tonight again and let you know if that was the cause. Thanks very much, had me worried for a bit, at least it was likely over nothing

It comes from de-burring the case with a Lee De-Burring tool. When you use it to do the outside case mouth and don't take care to keep it perpendicular to the case mouth, the knurled opening on the tool, drags against the brass, leaving a bright ring.
Simple cause and effect.
 
When you get older and get carpal tunnel syndrome from years of screw drivers and Lee tools you will need to step out of the dark ages. ;)

Do you use a Lee tool though? It'd quite different from most other manufacturers. Looks like this:

Inside chamfer is done with the pointy end, outside chamfer is done on the inside. If the base touches the case it can leave a mark. I switched to an RCBS tool because my Lee one got dull and took forever after around 500rnds. I love the simplicity of their case trimming system but their chamfer/debur tool is junk.
 
I tossed that Lee tool out shortly after I started reloading on their 50th Anniversary kit. I bought the Hornady one (very similar to the RCBS one but cheaper) and haven't looked back. Though a machine would be nice 'casue after doing 200+ cases in a sitting can give you sore forearms! In about 12mts I should have Popeye arms!

Same here! I replaced it with a Wilson and I am quite happy with it.
