Modified case-DIY
« on: July 30, 2023, 09:25:57 AM »
Getting ready to test a new bullet for our next range trip.
Hornady 90 grain A-Tip, and needed to measure 'Touch' in both AR's.
The wife has about 700 rounds on her barrel and I have about 3300 on mine (probably close to being shot out).
Since it's been a few hundreds rounds since I measured our current bullet choice, Berger 85.5, I measured both chambers with these also. 

Sized some fired loose primer pocket cases, 22 NosGar and 22 Nosler, just enough to chamber in the respective barrel, drilled out the pocket, inserted a Q-Tip, and epoxy in the neck. 
Slipped a bullet in each case, chambered the case by hand and pushed the bullet into 'Touch'.  Set barrel muzzle down and let the epoxy cure. 

Measured cartridge with a modified Hornady gage.  Brass blacked the cases for identification. 



Now to load up a seating depth test.  0.010", 0.020", 0.030" for the 85.5 and 0.020", 0.030", and 0.040" for the 90 (best guess). 
Touch length on Flo's chamber is still a little short for the 90. 

The 90's and 95's will probably be saved for 1000 yds (when we get there), the others are for 600.

Hey you found something made in the USA!

Good idea on the epoxy.  :)

What's the deal attached to the dial caliper? I have a good idea but don't know how it works with the caliper (zero?)

Can be used to measure bullet base to ogive or case base to ogive. 
Zero caliper against holder.
Subtract one inch for the holder.
