Have a CBI coming soon in 300 Win Mag (I hope), been waiting a long time, decided to try out the McGowan on this one. From everything I read so far is they are close in accuracy, CBI might have a slight edge, but to me its not enough to wait so long for a barrel. The McGowan will be a 223 Rem Match 7 twist, my stock barrel in 9 twist has served me well, the last 6 months or so the groups have been opening up, must have 7 - 10 k rounds through this barrel since 2006, it started out at 0.5 inch groups, now up to 1 inch, no complaints at all on this barrel, this is the Savage rifle that got me hooked on Savage bolt guns, I was in disbelief with its accuracy when I first shot it, not even an accustock, but is a accutrigger.
