| Is there a one step inside and outside deburring tool available for pistol cartridges? Loading a lot of 9 and 380 plated. If fhey were FMJ I wouldn't bother. |

Probably the closest you could come is a case prep tool with an inside and outside debur tools. I also prefer to debur pistol cases. Some folks will say it's not needed, I don't care, it's just how I roll. |

My pistol sizing die don't have expander balls. What you got? Quoted:

Why not trim, then size? The expander ball will flatten the burr and the inside of the case mouth will still be square, so you can get a proper crimp. My pistol sizing die don't have expander balls. What you got? Doh! LOL! I haven't loaded pistol in a while. I was thinking of the decapping stem. |

Yup but following you thoughts, the expander die might do a little of what you said but I think issue truly is not enough expanding by OP.. Normally I would recommend m die in those cases but in my experience, sometimes plated bullets are undersized and expanding too much is bad. |

Going one step farther - not a recommendation, just a thought...
If your cutter is sharp, why deburr at all? The burr will be microscopic. Even if your cutter is a bit dull, the tiny burr is unlikely to do anything other than improve your bullet retention. I wonder if Sinclair makes expander mandrels for pistol calibers. |

Negative, but I've found that if I don't debur the cases I'll ocassionaly shave some plating even with a solid flare. Quoted:

Your trimming all your pistol cases? Negative, but I've found that if I don't debur the cases I'll ocassionaly shave some plating even with a solid flare. Ok then why do you need to do the outside of the casing. Only the inside can shave. Motor |

Why not just flare the mouth more than you are to avoid the shaving? |

Some trim cutters are designed to chamfer in the same step, but the ones I have are all for rifle cartridges.
I don't see any reason those same ones don't apply to pistol sizes, but keep in mind that these cutter designs are picky about case thickness and the size state at the trimming step. In other words, they require a specific thickness and diameter of that case mouth to be effective. These go by names like 3-way cutters or similar. Mine are for the Forster hand lathe but there are several others. I think I would just give pistol cases a quick touch on a motorized debur tool and call it good, but YMMV. |

You still haven't answered how deburring ths outside of the casing is going to effect bullet shaving. You don't need a 3 way cutter. Unless you are trimming which you said you are not. Motor |

The only way to shave plating is to have it come in contact with the inside edge of the case mouth. If you have only barely enough flare (larger than bullet diameter) than its impossible to shave the bullet with the case mouth. So if you are shaving the plating you are either not flaring enough or you are seating and crimping in one operation and have your crimp adjusted too low (too much crimp) thus closing the case mouth before reaching full seat depth. If the case is flared properly and the crimp is adjusted to remove the flare only there is no physical reason to be shaving plating. My opinion is that you are looking for a tool to correct a problem in your procedure. Motor |
