Ron being trained how to use a gun was always going to end well, right? After his earlier lesson with Rick and Carl resulted in him not being allowed to fire off any bullets, there was always likely to be some comeback on that. The comeback here was Ron caused a mess in Olivias pantry so that he could distract her and then get access to her gun room and the masses of bullets that were stored there. With a handful of bullets in his possession, things are only going to go from bad to worse where Rons concerned as he has Carrrrrrrrl in his sights.
