No experience with the processes you speak of above.
I do have quite a bit of time-in-grade with rifles shooting jacketed lead-core bullets and now with Barnes TSX and TTSX bullets in several calibers--22 Hornet, 223, 243, 6.5 x 55, 7mm Rem Mag in a friend's rifle, 30-06, and 8 x 57. Without exception, all of my rifles shoot 30% to 50% larger groups with the Barnes bullets than with traditional lead-core jacketed bullets--best loads vs. best loads with each bullet type. I accept it as a cost of doing business in Kalifornistan (hunting). It might not be a diametric question you are dealing with, it might just be the limits of the Barnes bullets' material make-up. It's not all bad news, though--I have seen several examples of bullets recovered from game and varmints--expansion is reliable and impressive. FWIW.
We have been dealing with this Condor Cuddler Bullet nonsense (Thanks to Stanford U's "Center For Biological Diversity") since 2008. We do what we must to stay in the field, despite the State's best efforts to frustrate our hunts and complicate our regimens.
