Thread: Could finally be a Concentricity guage that works.

Cheers R93/Sneeze.

Good to know.

Was meaning "nice:" from a design/engineering perspective as opposed to "nice" a picture above your bed lol .


Im not a gunsmith and know piss all about chambering of a barrel, but would have thought it would be more likely for a chamber to be crooked to the bore than say parallel but off of the centerline of the bore.

That's exactly what I meant

If you used lee dies you would not need one!

I use cheap Hornady dies and I don't need one

I use all sorts of dies and i have a runout guage but this one is shiny , I want one.

A faultless argument I would suggest!

Yes, agreed...must be shiny....hahaha

I made this one a while back. It works great, but it only identifies the problem, it wont fix it.

If I lightly neck turn all my cases and fire them a couple times, I find that I rarely get a case that is far out. If I do, then it gets marked with a vivid across the back of the case/primer and put to one side for sighters, fouling shots etc...

I did extensive testing on run-out, and to be honest it had very little effect if kept within realistic ranges. Even at the extremes it didn't have enough effect to worry about testing it after initial case sorting/neck turning has been done.

It has always bothered me how you can have 50 to a 100 cases with little or no runout and you get one that wont play the game no matter how many times it has been fired.

Dunno about the accuracy one being a "Breakthrough design" looks a lot like a copy of Ferris Pindell's from the 1970's the Guy that co invented the 6mm ppc



Does anyone use a neco gauge or a neck wall thickness gauge to search for banana'ed cases like this? looks like a major pain in the arse but it makes you wonder how many bowed pieces of brass there are in a bag or box.

All good gear, I remember the old man rolling 303 rounds down a sheet of glass before a big shoot,
The wobly ones went in a tin for pig hunting.
