All my Mags are loaded with Hornady Critical Duty.
When I practice I alternate Mags each sesion. I strip out the CD ammo & use the Win white box for practice.
My Mags are labled 1,2 & 3. Rotating every practice session give them exercise & insures there working properly.
Example: I use Mag #2 during the entire practice session.
Next time I use Mag #3 the whole session etc......
