Since we have opened a semi-indoor range we are using non-toxic frangible ammo for much training/qualification. A couple of issues came up that may be of assistance to you handloaders. The Speer .45 ACP RHT ammo uses a small pistol primer. You may want to segregate it to avoid loading problems. I just set it aside and save it for when (and if) I have more small pistol primers than large. The Speer .223 RHT seems to resize very easily. Pressures must be lower than normal. The cases average about 1 grain lighter than Winchester commercial cases. Not much but should be taken into consideration during load development as the brass is "probably" thinner.
