Well, I was doing some brass prep today and switched to some 17 Fireball.

I set up the sizing/decapping die and dove in.

About 10 brass in, I set one down on the table and it rolled away from me. I noticed that it wobbled as it rolled, and the neck and shoulder didn't look like it was even close to being concentric or in alignment with the body of the brass.

I inspected my other sized brass and they were all in some stage of out-of-whack, which was really visible when rolling the brass on a flat surface.

I finally figured out the problem, which was the stem of my 17 FB RCBS die :eek::eek:

I have no idea how that could have happened (and how long it's been like this :what:) but I guess I should call RCBS for a replacement....

I discovered a bent decapper in my Redding 17 Remington die a couple years ago. My guess is the slenderness of the 17 caliber decapping rods promotes easy bending if the decapping force gets a little excessive.

I have been decapping with a universal decapping die of late, I guess with this new information, i will do separate decapping more religiously with 17 caliber cartridges.

Redding replaced my decapping rod. I am sure RCBS will do the same.
 
RCBS most definitely will ! I inherited some old reloading dies my Pop had, one depriming pin assembly was mashed beyond repair, how? I sent it to them with explanation, no problem, 4 days later a new deprime rod assembly was in the mail, no charge.

Duck, slow down son, don't hurry this project! LOL
 
I find that I bend these rods on my Dillon press. For some reason, the RCBS dies and the Dillon press cause a problem--can't adjust the .222 Rem. die and decapper rod to properly punch out the primer without the rod being at the bottom of the case when the ram is at the top position.

I bend them by having the die adjusted improperly--the rod hits the inside bottom of the case. Just takes a slight bit of pressure, and the rod is done for.

Still searching for a solution. Some of my dies I have to file off the base to get the proper sizing of the case--I'd have to put a bit of thought into whether this would work for the rod problem.

If I made my own LONGER decapping pin, all would be well. The pin is barely too short.
 
I have gotten into the habit of disassembling my dies (rifle and pistol) at regular intervals to look for things out of order. I usually find something that needs some sort of attention (polishing neck sizing mandrels for one thing).

Also, rifle dies can get crud build up (technical term) with case lube accumulation and bits-o-brass from the resizing operation.
