Being a LEO employed by a hospital, I'm totally on my own for anything rifle related for active shooter response but am allowed a personally provided rifle (in my case a PWS MK110) and ammo. By default, those of us that care enough to bring a rifle to work tend to just use the same ammo the city uses...Federal LE223T3. However since I'm spending my own money, I frequently end up using Speer 64 gr Gold Dot since it's usually cheaper. What I would need is a cheaper FMJ alternative so I can afford to train more that won't result in me having to re-zero my T1 at the beginning and end of every range session. All the surrounding agencies train with their duty ammo so didn't have any input.
