I got some S&B small pistol primers at a local gun club for nearly $10/k savings over the others. In a trial 9mm run they have performed flawlessly and with no noticeable difference from WSP etc.
Except they are very square shouldered and a bit different color, functionally in small short term test they seem just fine to me.
I did have MUCH trouble for unknown reasons with Tula, which often wanted to mount sideways in my 650 press.
