Debur cases

[KY DAN]

I am trimming 38 special cases, saami says 1.155 inches oal my lee is cutting 1.142. I am ok with this because it's only 1000 cases I am doing this too. This is match ammo and I want every controllable variable to be controlled.

After I trim I have a nice bur on the case I am trying to figure out a solution to this.

I have thought of taking a 19mm socket and filling it with scotch Brite pads and spinning on a battery operated impact.

Does anyone have a better solution?

That is exactly what I have done, after first using a chamfer tool, like on bottle necked cases.
The chamfer tool takes the burr off, then I polish the edge.
Using steel wool will work better as it doesn’t melt with heat. And it stays sharp, so one can get a good spot in the socket and not have to keep readjusting it.

I think I'm missing something. What is wrong with using a deburring tool? Just don't have one on hand?

I use a file (not coarse) while the case is still chucked on an electric drill. After I used the chamfer tool on the inside and outside.

I have multiple styles of debur tools at my disposal, I am looking for ways to make this as fast as possible.

Then just load them. After fifty or sixty loading cycles they will be smooth as silk.

The second fastest way is a chamfer tool and skip polishing.

If you are doing it like I do, you are not using the fastest way. You are using the best way.

Trim them, then throw them in a tumbler for a few hours.

I always chamfer/deburr after trimming. I trim .38 Spl to 1.140, but as long as they are between 1.140/1.145 I’m ok with it. Generally only have to trim .38 Spl cases once

I got one of these: https://www.midwayusa.com/product/101288634?pid=979270

The old version in the hard case, not the newer version in the soft case - but I kind of like that case!

My wife gets a giggle out of my case-prep routine. She refers to it as playing with my brass. Each one gets loving attention.

If you're in a hurry, buy factory ammo. Reloading is about getting it RIGHT every time, no screw ups, no shortcuts. One wrong step can mean a trip to the emergency room.

OP seems to be talking about the mouth OD, outside of the neck. I have used a 1/2" socket or a nut driver stuffed with coarse steel wool and it worked OK. This is prolly the easiest solution; https://www.amazon.com/Hornady-0501...rds=case+deburring+tool&qid=1632761032&sr=8-6

If they do then "invest" in a tool to deburr.chamfer

I'm not assembling match ammo but for the important rifle rounds I'll trim, chamfer/debur and finish with 0000 steel wool for baby-butt smooth.
