Case trimming question

[KFDiesel]

I trimmed back some 22-250 brass and around the case neck they are "sharp", actually the trimmed brass has kind of a Ridge around it. Should I just use a metal file and do the best I can?

Now you use an inside/outside chamfering tool on the case mouth. Just easy does it to remove the burrs.

This is the kind of deburring tool I use, though there are several designs.

Midway and others carry them for $10-15.

I've used the same tool used by Sam1911 for years and it does any excellent job. They are made by RCBS and any gun shop selling reloading equipment will have one. About 15.00.
