I know theses two cal. Differ in pressure head spacing and the chamber throats but why do I have so much trouble pressing in a primer even though I chamfered the primer pockets? Do they have different size pockets so there are more than one size small rifle primers? Any help appreciated! |

The primer pockets should be the same size. There may be slight differences in each companies tolerances or the reamer may not quite remove all of the crimp. I have not noticed a difference in pressing in primers. You can always get a chucking reamer to uniform the pockets. A half thousandths can make all the difference. |

I have a pocket cleaner and I ream a small chamfer but they seam to want to crush at starting to press them in, so I assumed the 5.56 used a different primer. So I'm sorting out the .223 from the 5.56 cases. All my cases are one I picked up the shooting range because it looks like very few who shoot them reload because I've picked up hundreds of these cases. I figured some day I would like to get a .223 rifle years ago so I collected the most prominent rifle round I found at the range and a couple years ago I bought a bolt action savage in .223 and that's my story. |

Small rifle primers are supposed to range from 0.1745-0.1765" in diameter. The interference fit is about one to three ten thousandths of an inch. You might need a primer pocket swager or a 0.1735" chucking reamer. Small rifle primers are supposed to range from 0.1745-0.1765". Or you can make a gauge if you have an electric drill and bolt with a smooth shank on it so you can turn it down to those dimensions and use a 223 case as a template. |

Thanks ! The reamer worked!! Seeing almost all the cases I have picked up are 5.56, now I can load both5.56 not just .223, thanks again. |
