Dear Ernest II/Daryl P./ Et AL:
If you want to reload a .223 without problems, buy new unprimed brass and new factory loads with uncrimped primers...that will solve your problems!
Don't use range pick-up brass, or military brass as both are likely to have had original crimped in primers.
For the cost of a Dillon swager at $100.00, you can buy a lifetime of .223 brass for reloading. And, use the correct shellholder...
Good Luck
