Of the two rounds mentioned, .284 and 338-06, I'd go with the latter. It will feed better.

I have a 6.5-284 on a Pre-64. It feeds great, but that took some work. The smith milled the follower rib back a bit to accommodate the fatter round.

'06 based rounds will for sure feed better as is, but the .284 can be made to work. The operative words are "made to work".

CFR action may be harder to adapt to a shorter, fatter found than push feed. I've heard that.
