Difference between primers (small rifle)

I find myself like a lot of reloaders out of Federal small rifle primers. I see a couple of different brands available in stock(limited places). How much difference will there be between them? Do I need to start load development again? Think I saw CCI, white river and 1 other(can't remember the brand).

I've been playing around with ginex primers recently, just swapped them in for the CCI ones I'd worked my load up with and to be honest I've noticed no difference. I think they may supposedly be a thinner cup but as i said they just do what thet meant too for me.

If you are ever over this way (Nelson) I have plenty of primers, powder, brass, projectiles, etc
