Like Doc Shapiro, I generally like the TO to be quiet and out of the way, but.....I've found it helpful when the TO lets me know I've jacked out a round, or lets me know shotgun KD's are down when I'm shooting black powder.
I bought a bunch of S&B's during the last primer shortage because that's all I could find at the time. They worked fine. They all went "bang", but I remember them being hard to seat in one (or two?) brands of brass. It might have even been non SASS rifle brass. Can't remember, it's been a while.
Huckleberry and George Emmett put on a SASS presentation at Sportsman's Warehouse in Milwaukee. I sold some modern guns to fund some old timey guns and have been hooked ever since. Couple of years later Johnny McCrae got me hooked on NCOWS. It's all kind of addicting!
