223 Federal Brass - Loose primer pockets ?

[Ol` Joe]

My reloads run in the neighborhood of 52,000 psi and I have seen loose primer pockets after 10-15 reloads with LC brass, but I have also encountered loose primer pockets after as few as 4 reloads. I suspect the variation may depend upon how aggressive the primer pocket was swagged.

Federal and lake city are sister plants both owned by AKT as are Speer, Alliant powder, Weaver, CCI, and few other sporting and military supply companies. I`d suspect the LC and Federal, and Speer brass is all made in the same plant.....JMO I could be mistaken
