The basic problem with primers is that they are all round and shiny, all look the same, but each lot is a little different from the last. But you can't tell the difference until you load them and shoot them.
As stated before, if you are shooting a maximum load, a primer change may lead to blown primers.
Most of my loads are midrange, and changing primers does not make much of an effect on the safety of my ammunition.
I have seen funnies, like WLP giving my 50 fps more velocity than Federals for the same charge and bullet. So WLP must be more energetic.
I have never had a problem going from WLP or WSP to CCI standard primers.
I did some testing of Wolf large pistol, based on a couple of loads, they are less energetic than WLP.
If you get a good deal on primers, buy in bulk and just keep shooting them. You won’t have to mess with cutting charges because you changed primers.
