Hornady concentricity tool

I have one and like it very much. I also bought the RCBS case master and found the Hornady tool to be easier to use. Just put your round in the tool and spin it with one finger. You can adjust anywhere on the bullet to check for run out. The RCBS tool you need to hold the case down with one finger and spin it with another. Glad I returned my case master.

Its the one I use and it is a Great tool! and you can adjust the runout with it also. the RCBS tool is a PITA to use and it wont fix them either! Thats if they need fixin... Buy Good Dies and set them up right and you would probably never need one, but nice to be able to Verifiy.

I have one and use it occasionally, depending on which dies I use. But it really depends on what kind of shooting you do. If you reload strictly for hunting, most dies you buy today are of such quality that you really don't need a concentricity tool at all. Now if you shoot paper for ultimate accuracy, different story. That's when you want one to check and make sure every finished casing/bullet concentricity is within .02 of every other casing in the group you are going to shoot. But overall, a nice tool to have if you are an accuracy freak like me.

Checking concentricity of ammo for a hunting rifle, other than the mental aspect, is not really productive IMO. For benchrest or competition it can contribute a bit to accuracy. The longer the range, the bigger part concentiricity plays in accuracy.
Made this tool, which checks case neck concentricity, wall thickness, case neck runout, bullet runout,and can even check iron sights for repeatability. By moving the 1/2" steel balls will check from .223 to 375 h&h lenght cartridges.
Check bullet runout on .375 h&h:
Bullet runout .223:
Case neck wall mandrel in place:
Checking neck wall thickness:
Checking accuracy of elevation clicks for repeatability on metalic sight:
Each 1/4 moa click = .003" and dial indicator can be set up to check windage adjustment as well as elevation.
