Shock Bottle vs Armananov Gauge

Hello Members

 

I recently acquired both the above 100 round gauges in 9mm. Out of a hundred rounds the Shock Bottle showed 

about 10 or so rounds sitting slightly high with one sitting a substantial bit higher. If I slightly push these rounds in they will go almost completely flush except for the extra high round.  When I placed these rounds in the Armananov gauge they all read flush.  What's that all about? I went to Shock Bottle's website  and read the FAQ section. Seems to make sense. I did do the plunk and rotate test and the high rounds did pass except for the extra high round which passed in the Armananov gauge. The barrel is a Kart fitted for a RO. I really don't know if I want to keep the Armananov gauge. Any real world experiences and or comments?

I like the SB because I can flip the rounds into my Dillon boxes.  If I get one that is tight in the SB I check it in a Dillon gauge.  If it passes the Dillon gauge It goes in the box, if not, it get recycled.

 

I did not know Lyman made a 100 round gauge.

The trick is to find a gauge that is smaller than your barrels chamber. So if a round sits proud in your gauge and fits your barrel you know your good. What I have learned is to use a maximum cartridge gauge, instead  of a gauge that is cut to minimum chamber dimensions. If your barrel is cut to minimum chamber dimensions, those dimensions are larger than a maximum case gauge dimensions. So any round that passes a maximum case gauge has to fit in a minimum cut chamber.

Also I just learned that this gauge is available as a "match" or "super match" grade. My unit is bare aluminum. 

Is this the super match unit? So is the anodized unit just the match grade? I did sent them a email for clarification.

Called Dawson Precision. The gentleman stated that if the gauge is a "super" unit it will be marked as such. 

Also he stated the anodized gauges are slightly looser due to the anodizing process. 

Waiting on email from Shockbottle concerning this statement.

I don't know about shock bottle but my EGW 4 hole has no "throat".  A sized case will gauge but a loaded round with any bearing surface above the case mouth will not.

My Lyman single has a long throat so a new load must be verified by plonk.

I also have both; but I did get the Armanov Case Gauge 3-in-1 bundle that included the OAL Checker and Brass Marking Stencil. 

 

I find myself primarily using the Armanov which comes with the free flip cover.  And, I like using the OAL Checker! 

 

This video offers up some of the highlights...............
