Neck Chamfering

[waltk]

I've recently taken up shooting Service Rifle. And of course all the reloading
that goes with it. My problem is I can't get a good outside chamfer on the case neck without a burr.
Inside no problem. I believe my tools are good and sharp but I always get a burr.
Any suggestions for a quick, efficient, way to do the job?

Hi Walt, Sounds like you may have a faulty deburring tool. Personally I'm more concerned about the chamfer since it guides the bullet into the neck. When I prep new or trimmed brass I run the necks into a nut driver packed w/ 000 or 0000 steel wool. Nut driver chucked into a drill motor. This will smooth the the neck rim nicely. Particularly, if you're shooting flat based bullets which tend to be skewed by an uneven chamfer. Also, if your chamfering tool is powered have you tried turning the tool in the opposite direction? Sometimes this will smooth the necks out.

What are you using for a deburring tool ?
Have you looked at it with a eye loupe to make sure there are no cut's on the edges ?
Have you tried a different tool ?
It's pretty hard to leave a burr unless your stopping and pulling straight back really quick.
If your using a torpedo type, just keep on lightly twisting it while your pulling it back slowly, and you should not leave a burr.

I am using name brand tools (Redding, RCBS).
I believe I've used different tools but I'll try again.
I'll also try different techniques.
Thanks for the replies.

Sorry, just gotta ask.
Are you trimming first?
Using something like Remchester brass out of the bag they require trimming first. Straightening/sizing also I should add.

Once thats done I use a VLD trimmer on everything.
The trick I use is by hand, don't just go in the cutting direction. Reverse it a little bit too.
Any burrs will get run down allowing the cutter to proceed smoothly on the next forward cut.
Works good for me.

Interesting because I have been using the same little hand C&H tool since the 50's with no issues. Might be a million necks done with it with no plans to change.

Go both ways but pay more attention to the inside.

I am curious if you are trying to remove too much material on the outside. I like to see a chamfer surface of about .01 to .015 on the inside. I just take off the sharp edge on the out side, no more than that. Remove the cutting tool while it is still moving, prevents fish hooking.

I have to apologize to the members for being a dummy. I put my RCBS mutli station tool aside and installed a Wilson outside chamfering tool into a Sinclair holder then chucked the whole thing into a small drill press running at slow speed and it works like a champ. Sorry, next time I'll
ponder on a problem a whole lot more.
