There are advantages to having perfectly clean brass. Those little bits of carbon get blasted down your barrel like sand paper, every shot. It's not like you're talking killing your barrel in 100 rounds, but it might make the difference between 3,500 rounds and 4,000, as examples.
Also, you can load highly precise ammo on a turret press. I use a Lee Classic Turret exclusively and routinely shoot 1/3-1/2 MOA at 100 and 3/4 MOA at 400. That with a bone-stock (except trigger) Ruger M77 MkII.
MidWayUSA has several options for dies in 6.5 Creedmore too.
