I got to say this. BR shooters are different in that some shoot short yardage game 100/200 and 300yd and they load at the range. Accuracy is conditions that may require changing loads and it can be from seating depth to neck tension etc.
If you look at those that shoot 600yd and 1000yd BR match that's different loading.
It's not a one size fit's all. If you look at the post I posted from 6br on F-Class open rifles and how they load that might differ from other type F-Class rifles so what Bart B maybe talking about without understand what type match rifles he's talking about is useless unless you can link it what match rifles he's talking about.
