An update on my post of 7/11. I finally got around to ordering a new shell holder. A Lee #19 so I had something to compare my RCBS #16 against. The Lee measured (from the bottom of the holder to the top of the deck the case sits on) .376 and the RCBS came in at .378. I put the Lee in my hand primer (RCBS 90200) and was able to seat consistently to .002. with one-handed effort instead of two with the RCBS holder. I think this is what a hand-primer should feel like when seating.

The RP brass used was picked at random, deprimed/sized while using the same CCI500 I'd used before.

I did try the RCBS and Lee in my RCII press and am still disappointed. The Lee averaged .001 and the RCBS was flush or ever so slightly proud. I still haven't figured this out. Maybe I'll run the plug out a little bit and see what gives.

I'm going to use the Lee for obvious reasons in the hand-primer. Happy with .002 and I'm going to run with it.

If someone has a RCBS #16 to measure, I would be interested in your measurements for a comparison also.


Not really sure what the "you'll develop a feeling or touch for how far to seat it" means. I have to go to full stop to seat between .002-.005. Is this normal?

I was using sized RP 9mm Luger but couldn't even get them off .000 for depth until I maxed the hand-held out. There is no touch to this but maybe that is the way it is.

I switched to sized Win and S&W and they primed better (easier) than the RP although they sized with quite a bit more effort than the RP. Roll pad RCBS lube was sparingly used for all three during sizing. Lyman carbide/sizing decaping die.

Do I need to ream these pockets out? Could my brand new RCBS #16 be out of spec? I couldn't even get the primers to seat correctly on my single stage. The S&W and Win seated really close to spec between .000 and .001 but wouldn't seat deeper. The RP seated at .000 or where you still feel the primer with your fingertip.

Hopefully, there is enough information for someone to tell me or guess at what is going on. I never, ever had priming problems using my single stage, rifle only, and this is strange to me.
 
Thanks for the info and update, I have Hornady and Lee, I've always thought they were all the same "standard" size the same as the dies are. I will measure mine the next time before I load to see the differences.

Thanks, for taking the time to measure.
