I saw them back in 2000 when I started collecting 45acp brass. Most back then were either Fed or Blazer. By 2005 a lot of indoor gun ranges switched over for health/safety reasons for their employees.
I throw all of the SP in a separate tub for when I run out of LPP. As for the load difference between SP vs LP, I see a 15-25 fps loss in velocity with the SP. Now if you look at the flash holes on the NT, the size is all over the place. During testing early by the mfg, the NT primers had a tendency to back primers out. Which is why they were crimped.
