I recently acquired a few hundred rounds of .223 brass with swaged primers. They don't seem to be too big of a deal to re-size/de-cap but the primer pocket has a pretty decent burr left on it that make pushing a new primer in almost impossible.
Do I just chamfer the primer pocket to get rid of that? Any suggestions for what tool I ought to use? |

You don't have swaged primers, the primers are standard sized. You have primers that have been crimped into place. Although crimped-in primers usually are easy to remove, you have to remove the crimp in the brass before you can insert a new primer. To remove the crimp in the brass, you use a swage or a trimmer, which are available from just about any reloading manufacturer. Although you can champher the pocket, it isn't recommended because you reduce the amount of brass that keeps the primer in the pocket and you increase the likelihood of popping primers. |

I agree with the last post. You need to remove the crimp first. I do however lightly chamfer each swaged pocket to remove the sharp top edge. This gives a nice angled surface for the primer to start in to and get aligned with the pocket. Think of it like a bevel based or boat tail bullet but in reverse.
I do this after swaging. |
 This pic is up in the FAQ's, you should do some reading there. Also read the 4 part "how to reload 223" series up in Tutorials. Will explain primer crimp in detail. eta,  And this is an example of a "Bubba" job of removing the crimp looks like on the left. The work of "reamer boy". On the right are cases that had the crimp removed with the Hornady reamer that has a positive stop. Link to the Hornady reamer. |
