Shell holders
I have used a Lee shell holder set for years. I got a new RCBS hand primer tool and I couldn't get the primers to seat deep enough. I bought an RCBS shell holder #3 to hand prime my .308 brass and now it proper seats my primers the proper .0085 depth.
I am wondering if anyone else has ever noticed a difference in shell holder based on brand? My caliper says there is .0005 difference between the base of the shell holder and primer grooves on the Lee vs RCBS, which doesn't explain the .004 difference in primer depth. |

Yes they have different center hole sizes and bench heights.

Yes l also noticed it when I ordered Redding bushing dies & a she'll holder. I inststalled the she'll holder in my RCBS Rockchucker press, the die was set first with the RCBS she'll holder , removed that shell holder installed the Redding the die had to be backed out. Both decks measure the same , the base is thicker.

I have the RCBS Universal primer tool
It had spring clips not a shell holder. Holds any size case, though it does require two different feeders and pins to push primer in for large and small (I got one each) Does a great job. |

I use the RCBS ram primer, works just fine. Can feel the primer bottom. What is important I feel , is to have your primer pockets uniformed to the same depth. I uniform all the pockets after the first firing . Never had a problem seating.

What I found is not really about primers but about degree of belling, seating depth, and crimp. If I have more than one brand of shell holder for a cartridge, my setup data has to include which shell holder number I used. I have only one RCBS. The others are Lee or Hornady. I have a shell holder from Hornady to match all my cartridges for the case trimmer, but Lee is often sized better for turret use, the Hornady a pretty sloppy fit to the head in some cases.

Well I have now proven that my Lee shell holder work in my rock chucker but my RCBS hand primer requires RCBS shell holders.

Funny how that happens. The Proprietary approach is good for their bottom line. Not so good for ours, though. Lots of manufacturers have adopted the concept.

Basically what happens g.willikers is that the RCBS shell holder hole is slightly smaller, and the thickness between the bottom of the holder and the ramp/slot is a couple hundredths difference. In my press and in my bench primer the difference is no big deal as you can adjust. But in my hand primer that difference= high primers. When seating bullets obviously you can just adjust the die, but not when using a hand primer.
