I've been looking all week and can't find any SPP in lead free. Does anyone have an idea where I can pick up a few thousand?

Here is a PDF article about the new DDNP primers. Its in PDF format:
That article makes me wonder about what if anything has been determined regarding the suitability of small primer 45acp brass for reloading. Specifically, the article's mention of possible variation in flash hole size with the lead free primer in the original factory loading. Not sure if that flash hole size is in fact different, and if so what that possible variable may introduce with regard to pressures obtained vs standard cases. I loaded 50 small primer 45acp cases for the first time ever just this past week. Didn't notice anything odd with regard to the flash hole. Maybe there was no difference.....maybe I just didn't notice? I'm not a big fan of maybe.....
I think the 45 ACP with enlarged flash holes, are actually a large primer. Ive loaded the small primered 45 ACP using the same data as LPP, and not noticed any difference in POI, or any pressure signs. They shot fine.
Here is a pic of 3 different 45ACP cases. The one on the far right is a Winchester brass that had a "green" primer in it. You can see the flashole is enlarged. The middle case is a standard large primer pocket 45 ACP, the left is the small primer pocket 45 ACP.
Handloader mag had an article about the small primer pocket 45 ACP cases. They stated that performance was actually enhanced using the regular small pistol primer 45 case over the larger one.
I think the real issue is using the DDNP primers with current data for regular primers.
