Do you mean not the way the Redding tech suggested ?

Yes. I just take 6.5x284 Lapua brass and run them through my 6mmx284 sizing die. I lube the inside of the necks good as well as the outside, pull the ram, prime, dump some powder in, seat a bullet, and go to boomin!! It works just fine that way

Re: Necking down from 6.5 to 6mm

I just put together a 6mm-284. I chose 6.5-284 norma brass and used a hornady die set. The FL die worked but the die's neck ID was .264" which IMO is too small. The die sized the necks way past a useful dimension and pulling the necks over the sizer ball was extremely difficult even with imperial sizing wax inside the necks. The end result was some very stiff necks and high neck tension. The necks were so stiff that seating or pulling a bullet was unbelieveably hard. I had to ruin bullets in a RCBS collet die to remove them from loaded rounds. I wasn't sure if the brass was work hardened or improperly anealed from the factory.

After this mess, I talked to Redding and they also said to use the seating die as the first step. I asked if I could perhaps use a series of bushings in a S die and they said it wouldn't work.

I ordered 100 pcs of Lapua brass and made my own forming die. I chopped off the shank section of a burned out .264 win mag, threaded it 7/8-14 and ran in the reamer. The result was a die that necked the brass from .290" to .277". Then I used a .272 bushing in my S series die. No overworking of the necks and no running over a sizer ball.

FYI the redding FL die will reduce the OD of the necks to .268".

You can buy a die blank from several sources and get your gunsmith to chamber it, shouldn't cost much and IMO it would be money well spent. Redding seating die costs $56. Your choice.
