Concentricity gage

[GrizleyHunter]

It looks like I might purchase the sinclair gage but unlike the Hornady gage which you can also adjust runout of the bullet you can not with the Sinclair.But I like the looks of the Sinclair gage better.
So question is how do you adjust the runout after you find that you do have a problem.

I am glad you asked this question! I also just ordered the sinclair concentricity gauge! I cant wait til it gets here!!!

It adds a little more time, but the ones that have posted the solution say it works...Others will use a neck turning tool to true up the case necks..

I use Forster Benchrest dies and, so far, have never noticed a problem with runout when I roll them across a mirror...If I were into hard core bench competition, I might find a need for the runout gauge, but since mine come out so close to perfect, I just can't justify the additional cost..

OT
I also turn my rounds when seating,But it still make me wonder if I do have a neck problem or bullet run out if I dont have a gage to show me that I do or not so that is the reason I want one.I hate quess work and just want to know for sure.
Question still is how do you correct the bullet run out after you find you do have a problem??

Grizley,
For the reasons you state, I bought both the Sinclair and Hornady gauges. The Sinclair allows me to check the necks, but I am not "thrilled" with the manner in which casings are rolled/turned. The Hornady on the other hands, allows me to make concentricity corrections on any loaded cartridge and maintains an even plane when turning the finished cartridge as opposed to relying on keeping even pressure with your finger on as on the Sinclair model. BTW, you might be somewhat surprised on how badly off some of the necks are on some "new" casings including the most expensive and more reliable brass can be.
