After a little over 3 years and $6,600 worth of materials, counting the powder, bullets, primers, barrels, chamber jobs, brass to fire a little under 4400 rounds, my original 284 WIN brass primer pockets were so loose, it was time to do something. Over 100 cases would not keep a primer in. Ok, I shoot a hot load, but after 10-12 firings, they get loose! Now my rifle is a tight necked straight 284 with a .312 neck so all brass has to be prep’d big time, regardless of make, and I have a lot of time and energy into these 500+ cases! (FL sizing without the expander, trim to same lengths, inside and outside neck deburring, inside flash hole deburring, inside primer pocket depth uniformed, mandrelling up to 284, neck turning, cleaning, priming, loading, fire forming, re-cleaning, weight sorting).
I was talking to a buddy (GT) and he said he has the fix for this! He sent me these pics and specs and said HR made him "nubs" for both LR and SR pockets! So I had HR make me a LR one!
The tool, basically pushes, via a loading press, a small amount of case base material from around the edge of the primer pocket hole into the hole itself to create a small ring/ridge in the primer pocket to hold a primer tight again.
You need a pocket swagger die to hold the inside of the brass down while pushing the brass into the primer pocket hole.
RCBS sells one for removing military crimps from pockets...
Put the tool in the press,
place the case remover collar over the tool,
put a case on the tool, (you have to raise the ram some to have the tip stick thru the opening of the removal collar)
stroke it,
and you get...
This works! Holds primers like new again or even tighter! Loose pockets go from 0.207-0.212 to 0.2045 to 0.2055 and primers stay in them now. I reloaded and fired 30 of these "fixed" cases a few days ago, in -30 C weather and none leaked and all required good force to de-prime them again!
Cost... about $50 for the RCBS swagger die and $40 to have the tool made.
Here is the SAAMI drawing for primers and pockets...
Thanks GT for the tip and pics and thanks HR for making it for me.
(Most Canadian competitors will know who these two gents are
)
GT is an FOpen shooter and HR is a master machinist who does all my rifles.
How I set this tool and die up.... place a case on the tool, raise the ram all the way up, screw the dies down so it has lots of threads in the press to hold things, and screw the center rod down till it touches the bottom of the stroked case, lower the ram so you are just before or starting into the cam over, screw the rod down to the new location. This setup allows you the power of the cam over to push a small amount of brass into the pocket hole. You will need some force to remove the case from the tool or your not pushing enough material. GT says he just does it "by feel" because you can feel the brass moving.
