On his website David Tubb says: “A detailed study of large and small rifle primers showed that large rifle primers worked best when the propellant charge exceeds 35 grains as is the case with the 6XC.” I would consider Tubb the last word on the 6XC.
Since the 6.5 Creedmoor normally uses more than 35 grains of powder, I haven't bothered with the small-primer Lapua cases, partly because I've had such great results with Hornady brass.
I agree with you. I have also had such good results with the Hornady brass that there's no need to play around with gimmicks. I've encountered so many people (on the rifle team, at some serious national matches, or even higher profile folks) who don't even know _how_ to analyze data, nevermind whether they actually _do_ try to analyze data, that I don't pay any attention when someone says they 'discerned' a lower SD.
