I did not know there was any difference between the three. AFAIK, and I could be wrong, each of them is merely a 284 Win case necked down to 6.5 aka 264 diameter. No changes to the case body,shoulder or neck to any of them that I ever heard of.
I will be staying up with this thread to see if there is a difference that I was not aware of.

I think the rear diameters are different (at least) and the original 6.5-284 Win chamber dimensions have a larger size at the rear compared to the case size due to the original actions the parent .284 cartridge was chambered in; M88 and M100 Winchesters. Long range bolt shooters found they wanted to tighten up the rear of the chamber to avoid loosened primer pockets.

If you are building on a short action then the Winchester version. You won't be able to seat 140 VLD's.
Long action go with the Norma.
Only difference is bullet seating depth.

KK alaska i is right. But then I had an action that would accept both brands of brass.
I used Lapua but could neck down Win (white box) 284 brass too.

What kind of barrel life could a guy expect if he kept the barrel on the cooler side?

Unsure on barrel life, but if I had to do it all over again I would do a 6.5 06 on a LA.

I was thinking a Defiance XM action would be just right for length!

Mine is a 6-284 Win. It is chambered with a Win reamer. But since Win brass is darned near impossible to find, I wish it had been chambered with a Norma reamer.
I am using 6.5-284 Norma brass manufactured by Hornady.

I Have my own reamer and can use any brass out there. I decided that I wanted the existing resizing dies to work with my base diameter and I throated it for 140 VLDs. My reamer is not the best one for a short action though. There are reamers with longer throats than mine too. Neck diameters are all over the place as well. I like .298" for the necks. This is a reasonable no-turn neck. I mostly use Lapua brass. The Hornady brass is not as good. Most W-W brass is not as good either.

I used a 6.5x284 for a number of years in LR competition. 48.5 grs of N160 and a 142 Sierra was the cats ass but never got more than 750 accurate rounds out of a barrel. Usually shot 24-26 rounds in 22 minutes.
