Default How Much to Chamfer?

I just got the Frankfort Arsenal Case Prep Center and am pretty happy with it. The trim length is set and itís pretty dead on. Couple thousands of an inch deviation sometimes but Iím happy with it.

But how much should I chamfer? The videos of the device I have seen show one or two seconds. When I do it I can see the brass shavings coming off. Can I be taking off too much? Can taking off too much make the case unsafe to load?

Been loading handgun ammo for about 7 years and never had to worry about trimming or case prep. This is my first attempt at rifle so I wanna make sure I do it right. Thanks.

Default Chamfering

You'll do a few cases and figure it out. What I mean is that unless you chamfer so much that the OAL of the case is shortened, whatever you chamfer is OK. UNLESS your going to crimp the case onto the bullet, something in the 40 plus years Ive reloaded rifle cartridges Ive never done.

If your seating boattail bullets you probably won't need "as much" of a chamfer as if your using a very flat base bullets. I only use jacketed bullets.

A issue you may have if your using a "machine" to chamfer (vs by hand) is that if the case OAL is different the chamfer will be of different amounts.

Just try a case or two. You'll "know" if the chamfer is GTG by just looking at it.

Just enough to "break" the sharp edge and remove any burr.

IMO - this IS THE answer. You don't need to do ANY more PERIOD.

Yes, I concur also. Just enough to remove the burrs. You don't want to make a knife edge on the lip of the case.

If you have a handy little cheap LEE chamfer tool. Then you turn it once or twice that's how much. Move on to power tools and just a very light touch. Kinda like trigger jobs with a Dremel!

Default Don't remove a lot of material...

I just turn until the mouth has a bright ring inside. Shavings are minimal. I have trimmers for trimming if need by.

Chamfer just enough to remove any sharp edge or burr from a newly trimmed case . The least amount is best .
You DO NOT chamfer every time you reload a case...only when trimmed.
Chamfering is NOT used in place of neck expanding and/or case mouth flaring to get bullets seated into cases .

If doing rifle cases after trimming to length, removing any extra material from the outside & inside of the case mouth is necessary. Beyond that,you're really just breaking any sharp edges. If you're loading precision ammo, the use of a Lyman M type die to produce a uniform neck tension and very slight flare to the case mouth to get the bullets started straight into the case is helpful. If you seat primers on the press, you can do this at the same time you seat primers.

And make sure you chanfer all cases the same amount. Specially in the calibers that don't get crimped.

Some want to "chamfer" to make bullet seating easier, I don't.If I need to make bullet seating easier, I'll flare the case mouth (the amount of flare depending on the type of bullet used). Most "chamfer" to debur and remove the sharp corner. Excessive chamfering can cause a sharp (knife) edge on the case mouth (I experienced a major "ouchie" with a sharp mouth case. I was resizing some 38 Special brass that had a bit too much chamfer on the mouth and I was on a roll. I placed a case in the shell holder but didn't get my finger out of the way quick enough and cut a nice 35 caliber chunk out of my index finger.)
