Barrel make is personal preference. All the makers you list make good barrels and you really can't go by match reports as there is too much so and so wins with x make of barrel then there will be a lot of shooters the next year or sooner shooting x make of barrel. That doesn't mean the makes not listed in the match reports aren't good barrels just not the current popular make. You'll also find that people tend to use the barrels of makers they know personally. I know I do. When I want to install a barrel on one of my benchest rifles, I look for the twist rate, caliber and contour in my barrel rack and then maker last. For a 66 to 68 gr. 6 mm, a 14 twist is pretty hard to beat, 13.5 would be my next choice. Very few are shooting heavier bullets in 100/200 yard competition. For 107's, I normally go with a 8 twist barrel, but it will be in a 6 BR not a PPC.
