I am not willing to burn up 200 rounds of good barrel life on a competition barrel that may only last 1000 rounds and one season. That is what forming with bullets does for my 6 BRA.
Finding a competitive and well-tuned load that would allow taking unfired cases to a match would be an exercise in futility. Chances are that by the time the load was tuned to my satisfaction I wouldn't have enough unfired cases to cover the match, so I would also need a tuned load for the fired cases. It's much better to use the exceedingly simple and reliable 20 grains of Bullseye and 1/8 sheet of TP for when a fireforming barrel is not available.
In a hunting rifle that needs only 50-100 cases and won't shoot 1000 rounds in 20 years, it doesn't matter.
I've read many accounts of competitive shooters shooting in matches with bullets heavily jammed to (fire)form different versions of the 6BR case. Shortly I'll be with a 6BRA and 6BRX, probably doing the same thing.
