I just ordered a CA ridgeline in 6.5X284 for me nephew and will be handloading everything for it. My proposed die setup:
Forster FL sizer
Forster micrometer seater
Whidden type S bushing FL sizer.
My idea behind two sizers, I'll measure the neck OD after sizing w/ the non bushing die, and if it falls in that 289-290 od measure, and then expand w/ mandrels to 291, then seat a bullet to 293. I'll run the FL die. If I have to use bushings, so be it. From sounds of it, lapua is a bit tight to the 297 chamber ID, so I'll probably end up turning. You guys have better suggestions for dies! Thanks!
