6-284 to 257-284

[nmkid]

I have 200 Lapua 6.5-284 cases that have been sized down to 6-284. The cases still have a lot of life left in them and I was wondering what is the correct method to get them back up to .257 for a new 25-284?

I know of no more correct method than running it in the 25 Cal sizer die and annealing if need be... you're only moving the neck walls one caliber...which in this case in sized form only differs .007" per side or .014" total...just my 2 centavos. Kev

Have the necks been turned?
