This weekend I bought a Ruger American Ranch in 300 BO, the first new caliber I've added since maybe the 1990s. Back then I loaded a lot of ammo in 221 Fireball, 223, and 308 in Redding dies, so that's what I was thinking about buying now. I also eventually plan on building a pistol in 300. I plan on using factory brass and don't plan on forming any.
I'm wondering what are the current opinions on rifle die brands.
