if loading.284 calibre use the .277 ball
if loading .277 use the .264
if loading 6.5mm use the one for .25 cal
if doing .25 use the 6mm
if doing .224 use the .204

so your dies still function the way the always have,but the neck is only expanded back out a LITTLE bit...still going to be tighter than with normal expander ball...

we did it with 7.62x39mm,I just stopped using the .311 ball/rod and kept the .308 one in as usually used those projectiles anyway.

but the neck is only expanded back out a LITTLE bit...still going to be tighter than with normal expander ball...
You have annealed your brass. Sized. The neck is perfect. Why do you have to "expand" it a bit more? You chamfer the inside of the neck so no shaving. The projectile seats with out any issue and you have perfect tension. 2C. Annealing makes the case a perfect fit [in all dimensions] All the gorilla stuff with work hardened brass is a distant memory. You add in an unnecessary step with the expander. Why do you need to expand it? The projectile should fit inside the case mouth each and every time because it has been properly sized.
