Well, I voted "I don't know". That's not because I don't know, but because each gun is different. Just off the lands for one gun could be fifteen thou. and just off the lands for another could be 50 thou.
I have pretty good success with Nosler bullets, however I also have good success with Hornady's. Most of my loads are Noslers.
I do have a 243 Encore barrel that I load an 80 grain Nosler to SAMI specs and it shoots sub-MOA. I could fool with it and see if I could make it better, but I dunno if better than 1\2" @ 100 yards will make me happier. I guess it could, but that will hit anything I'm going to aim at out to 300 yards. Maybe if I get bored I'll fool with it.
