Welcome aboard Dave. Hornady has always been inconsistent with their primers and uses whatever they can get their hands on. This predates the current environment. In the current environment, I'd guess that they are using foreign primers. I can't see how Vista or Winchester could be selling them primers in the current market when they can't make enough ammo themselves.
I would just shoot the factory ammo. Load development in virgin cases will not give you repeatable results when you switch to fired brass since the volume of a virgin case will be below the volume of a sized fired case. It may also result in different neck tension unless you run the brass through your die with the decap pin removed. But then you run into the issue of how to remove the lube on the inside of the neck with a primer in there......
