Thread: So how much difference does the primer make?

I have a reloading manual "Any shot you want" by A Square and has a lot of good info. One section they compare various primers of the same size ( eg Standard ,etc). the results showed that there was a difference in the pressure between different primers.
I have never worried to much about it especially in my early days of loading, these days I try to stick to the same brands. I haven't noticed a difference in points of impact when using different primers.
