New Ammo Test
One thing I do when changing ammo is to function test it. Is the POI different? Does it feed? Does it cycle? Yadda, yadda. You get it.
But this is important. Don’t show up at a training, class or qualification with shiny, brand new, untested ammo. If it all is going to go wrong, better to do that on your time, than someone else’s.
