284 Win Dies

[jugi16]

Going to be buying a 284 Win that was chambered with a 284 Match Reamer. Thinking of necking up 6.5/284 Lapua brass in 2 stages from .264 to .277 then to .284 with some mandrels from Sinclairs.

I would like to neck size only after I fire form, and Lee doesn't make a collet die. Just wondering what dies out there people were using for the 284. I presume Redding S bushing type dies. What bushing size will I need for the Lapua brass.

Thanks

You might consider K and M mandrel ex panders as well, they seem to be a little sturdier than sinclairs
