i have been seting up my redding bushing dies for a 6br. i have never used bushing dies. i read the paoer work and have them set right. the bushing only sizes about 1/3 of the neck on both fl and nk bushing dies. . is this the way bushing dies work? i have a nk die for another cal that will size the entire nk. the bushing is .269 . the gun shot good with these dies from the person that had the gun and dies before me. i am just new to bushing dies. thanks
