I loaded up some .45 ACP rounds with small primer brass I picked up from a member a while back. I'll use them in the indoor range so I don't have to worry about losing the brass that goes down range (yes, as a reloader I usually hate that). I have an RCBS Pro Chucker progressive press dedicated to .45 ACP, but since these are small primer I loaded them on my single-stage Rock Chucker. After some 35 years and with 3 progressive presses on the bench, I still enjoy single-stage reloading.
