Thought I would get your opinions on 5.56 primer pockets, I have about six cases from the last batch that the pockets are very loose. I can't pick the primer out with my finger nail, but they went in very easily. I prime with the RCBS automatic bench priming tool so I can easily feel the difference.
The brass checks out fine except for the pockets and I just don't want to be cheap and cause major issues, I have plenty enough cases. RCBS a) Scrap the cases b) Load them as light plinker loads then scrap them next time c) have another beer and worry about something else Thanks, |

Hart makes tools to tighten primer pockets. Unless we be talking LaPua, I'm not interested in salvaging brass over a loose pocket. Throw'em in the scrap bucket. You know that old saying ? If you always do what you've always done you will always get what you've always got.
This parables well to reloading loose primer pockets. Only exception being you might get full auto when you least want it. Primers have a way of finding the trigger group. Load Smart, dc. |

Quoted:
What's it called? Gas cutting? Once my pockets loosen, I use a sharpy to mark the case head and toss it after the last firing. +1 and what Areo said. I use a Lee hand primer. If they go in easy and banging the rim on the bench doesn't move the primer, I color the head of the case with a sharpy. I use them only for practice, etc. As I pick up fired brass, I throw those away. |

Quoted:
Measure a primer. Then look for or make a pin gage that will give you about a .001 interfearance fit. Swage lightly and ream a bit if needed. Do not overswage the pockets as the crimp may be the only thing holding the primer in. Worked for me. db This is my question. Is the FC stuff 5.56 or .223? Are you reaming or swaging the pocket? I have a ton of XM193 brass from about 2009 and I just bought the RCBS bench mount swager. Now I'm kind of worried about swaging. Do I even need to. I'm kind of new, so I don't know if I would notice a "loose" primer. |

I'm kind of new, so I don't know if I would notice a "loose" primer. I imagine the 2009 m193 was crimped. Look for a crimp ring around the primer pocket. Don't over-swage. It is a pain in the ass, but I iterate between adjusting the amount if swage and primer seating. I swage lightly, then try to hand prime. If my primer tool jams, then I disassemble and un-jam. Then, I swage a little harder, then try again until I have a minimum swage setting that allows primers to seat. |

I'm kind of new, so I don't know if I would notice a "loose" primer. Up in FAQ's there is a pic of primer crimp you should study. Also what your swaged cases should look like. Swage a case, seat primer, adjust swager as needed. Don't swage the whole batch and discover you under or over swaged. Remember web thickness varies between brand of cases, so sort by headstamp. Loose primer pockets; 1) Seat some primers in some once fired commercial (no crimp) cases, think Winchester here. This lets you know how much force is needed to normally seat primers. 2) Loose primer pockets will seat very easily, much less force needed than with once fired commercial (no crimp) cases. 3) Train yourself to feel the bottom of the primer pocket when primer bottoms out. Some practice seating primers, and the loose primer pockets will be very obvious. Sorry but FC cases are notorious for loose primer pockets. Good luck

Quoted: I wish all you FC brass haters would save it for me. With 223 pressure loads I find recent small letter FC brass the equal of LC brass. The only recent brass I have found problematic is 2010 and 2011 LC because the necks split early. Don't hate it, just trade it off. Not worth the case prep, use it if you want.

Or maybe I just happen to find RP cases that have been fired 10 times.
