now that i have your attention: i've been using srp for pistol reloading(about a year)since i heard it's fine to do so(per arf). i use those same primers for my ar loads(not hot, just plinking). question is when i order from PV should i order srp or the 223? i think that's what it's called, maybe 556. tia Wanna kill these ads? We can help!
