Quick question

As you likely noticed by now, the BR2 is the benchrest large rifle primer that CCI offers. If you got them for the price of the regular LR caps then you probably got a good deal on them. And as long as you are not going to use them in magnum case you should be fine. I say this because I tried them in a .264 Win mag and got a couple of hang fires. I did not like that. I have used them in my .220 Swift, my .243 and my .308 but as they cost a bit more than the regular primers and the accuracy difference was nil I quit buying them.

I would just use them if I were you. Good caps them be. I like them anyway.
 
I say minimize different components to eliminate variables. I do believe changing primers will affect accuracy. Sometimes not enough to see, sometimes you will. Depends on the firearm.

I've seen a primer change make a good load better, but sometimes it goes the other way. I doubt you will see any change in the BR over the standard. Change brands, and then you can expect slight changes.

If your pushing maximum, load a few at a reduced load to be safe.

They can. The only way to know for sure if any particular ones do is to shoot some groups & find out. I have seen either negligible or dramatic differences, meaning not big enough to bother worrying about and from sub-MOA to over 3 MOA.
 
They should not change it that much but like others have said they could. So the safe thing to do would be to drop the charge 1.5 gr and re-work the load. It is what I have done when changing primers.

Because some primers run much hotter than others. So, changing primers can change pressures.
