Just backordered one of these babies from Midway. Hornady says suggested retail is $127. Midway sells them for $94.99.


Tried to include a link to a pic but I'm too stupid to figure it out. Looks like you can measure runout anywhere on the finished cartridge. Says you can use it to remove the runout, but I dont exactly see how.

I use comp dies so I'm hopin there will not be much runout.
 
Re: Hornady LNL Cartridge Concentricity Gage

I got one it's a waste of money, I bought it to straighten an assload of 30-06 Garande ammo I got cheap, I also have a Sinclair Concentricity Gauge, the Sinclair unit can be used at each step of the loading process, Hornady only does loaded ammo, numerous times the Hornady reads zero, the Sinclair reads .005 or more, I don't trust nor would I recommend the Hornady unit to anybody.

Midway doesn't list a Sinclair concentricity gage. They do have a Forster, Hollands, and RCBS. Any opinions?

The Sinclair is $85 and does not even come with a gage.
 
Re: Hornady LNL Cartridge Concentricity Gage

Got my Sinclair Concentricity gage yesterday. Nice tool! (thats what she said...) Anyway, highly adjustable, good instructions. Instructions stated to resize without decapper rod, and measure runout. Then reinsert decapper, resize, and remeasure in order to see if the neck expander is adding runout.

Out of 50 completed rounds, only 11 had more than .002 runout. Of those, only 1 had more than .003. All 11 were brought to within .002. I'm pleasantly suprised at the low numbers produced by RCBS comp dies on a Lyman TMag turret press.

As a newbee to this thing, <.002 seems to be an acceptable runout. Do you guys agree? This is tactical rifle ammo, not benchrest.

Thanks for the advice on the purchase, 427Cobra.
