primers- brass shavings

Have been loading 9mm 45 ACP's 38's 357's with great success. Now having trouble with 223's. My primers some aren't seating correctly and I notice there seems to be some brass shavings from the primer pocket and some sharp edges on the primers. CCI small rifle primers are being used and the small primer bowl. I did notice on occasion the bolt to the plate does come loose and yet the screw to the piston in tight. Any help would be appreciated. And this is the cadiliac of all presses out there.

Be sure the brass tip on the set screw that secures the shellplate bolt is intact. Sometimes these can fall out. Usually a shellplate bolts tightens instead of loosens, due to the direction the shellplate rotates. Be sure the spring wire that keeps the case from backing out of the shellplate at station1 is adjusted to not quite touch the case. It should be within .002-.004" of the rim of the case.

 Be sure you are either loading commercial brass or if military, that it has been properly swaged to remove the crimp surrounding the primer pocket.

As been mentioned be sure it is not once fired Military brass with crimped primers.
If it is the crimp has to be removed before repriming.
The Dillon Super Swager works great for this.

Just curious Were these casings military perhaps maybe they needed swaged. I have gotten a few in the past that looked fine. Until in the press and found out that they had not been properly swaged before. Just a thought.  Terry

As mentioned primer pockets may need swaged. I had this problem on Federal AE value pack ammo from Walmart as well. Swaged the pockets with the Super Swage 600 and primers seat properly now.
