How to fix "nicks" on extractor rims?
- Thread starter PolarFBear
- Start date
The only guage I use is for 556 and 308 to set the sizing die.
I have no gauge for all the handgun calibers. If I did all I would be doing is dropping brass in gauges,
If the rounds pas the plunk test they are good to go for me in many assorted guns and calibers.
If the OP has a defect in his extractor then that should be addressed.

Using a case gague is smart ...keep doing it ( I check all my reloads - about 10 boxes a week - and it assures me they will feed properly ). I want to catch these issues so I won't have any feeding issues in a match..
On cartridges I reject with case nicks ....if there are only a few, I will use a file by hand to clean them up / but if I happen to sweep up quite a few beat up cases at my indoor range, I try and weed them out prior to cleaning, by rolling them around in my fingers...( it's not my guns that are causing the nicks ). Some cases with minor nicks will pass the case gague plunk in and out test...some won't..../ but I won't shoot a round unless it passes the case gague.
For cases I don't like the looks of...I pull the bullets ...reclaim bullet and powder ( put ear muff on...and fire primers into my shop garbage can) - and recycle the cases to a brass scrapper ...

FIXED: "nicked" extractor rims
I posed my troubles to Lee Precision with a suggestion that a new product could be in order: a chamber cutter for extractor ends. I also said I was going to try the Lee Bulge Buster as a possible "fix". Here is the Lee reply.
"Thanks for the rim trimmer suggestion. I am certain the bulge buster
will iron out any rim burrs that would impede proper function.
Sincerely,
John Lee, President"
The Bulge Buster worked like a champ. I "busted" 244 Speer Lawman .45 acp's with no troubles. Passed them trough a Dillon 550b. Loaded 200 gr LSWCs from Lasercut bullets over 5.0 gr HP38. Every one passed the gage test. Thanks for all the insightful replies. "Aim straight, shoot straight".
I strongly recommend the Lee Bulge Buster.

Dillon Vs Lyman
A final note on my case head aggravation: Stopped in to a Bass Pro, had a Xmas gift card to burn, and picked up a Lyman case gage. This is the model that does six calibers. Tried some of my Speer Lawman reloads. They "passed" on the Lyman gage but "failed" on the Dillon. I guess SAAMI specs are different at the two companies. I trust both firms as a Gold Standard but now I am curious.

Even SAAMI lists a range of dimensions for the case and the chamber for every cartridge they show specs for.
PolarFBear:
Which Lyman case gauge? There are a few things to consider when using a case gauge, starting with which dimensions it actually looks at. For example most case gauges like these:
Lyman
Wilson
Dillon
Look at a few case features but for example ignore case diameter(s). I only used Lyman and Wilson as examples as there are other similar gauges. The manufacturers do explain their gauges and what dimensions they measure. There are a few newer case gauges out there like:
Sheridan Engineering
These gauges are cut to chamber specifications including diameter. Likely the best gauge available is your own chamber. Resize a case, trim as necessary and see if the sized case chambers in your rifle(s). Most off the shelf case gauges are really little more than a Go/NoGo gauge as they really don't provide a numeric value. They can be used with a good straight edge (steel pocket rule) and some good feeler gauges to get a numeric value as long as the case gauge manufacturer tells you what their gauge is and the step values but this will always go back to your chamber.
