Berger Reloading Manual Doesn't List Primers?

I'm trying to work up a load for my 7mm-08 using Berger 140 grain VLD Hunting bullets. I found the load data in their Reloading Manual, but I can't find where they specify what primer they used for the testing. Maybe I'm looking in the wrong place. I understand that blindly substituting primers can lead to unsafe pressures. I looked at the FAQs on their website and can't find any discussion of what primers they used.

I have the manual and you are correct. They don't recommend primers. Help me understand (not being a smarty pants) but why would primers change your pressures?

Some of the loading manuals I've read say primer choice makes a big difference in pressures.

When switching from LR to LR mag no doudt, there's is some difference from LR to LR just drop back .5 when switching and you will be fine

Even switching from a standard primer to a magnum primer may or may not change anything.
I switched from BR2 to Fed 210M with no change in pressure or velocity, this was tested in the Pressure Trace II.
Switching from a WLRM to Fed 215 reduced pressure by 8,000psi.
Over the Pressure Trace, WLR/WLRM are the hottest primers I have tested to date.
Rem primers are the weakest, running at least 10,000psi less than their counterparts by CCI, Federal or Winchester.

Cheers.

I guess some like to see all the specs that made up a load. Some keep better records and some would mix cases and just load.
The variables matter but perhaps more so for precision shooters than most hunters.
