Just my experience, but, I really just want the barrel to be the contour and twist combo that I desire for a given project. Just lucky I guess that I've never had a "bad" barrel. Lilja, Krieger, Rock, Brux, Bartlein, and McGowan off the top of my head. The only "fussy" one of the bunch was the 1:8 Krieger in 223AI. No big deal but I had to hunt a little for powder to get the accuracy I wanted from 75gn A-max's. Everything else I was able to use my intended/pre-conceived powder/bullet combo to excellent results, which for me, is the whole reason behind a re-barrel in the 1st place.
On the rifles that get "hunted" the most I've got 2 Lija 3-groove. A #3 1:10 in 257Wby and a Kimber MT dupe in 1:8 270Win. 3rd is a button-rifled Rock in 1:8 22-250. They all work for their intended purpose.
I'm typically more time-bound by sourcing parts than anything else.
