I know for the 30-06 Win holds about 1 grain more than Rem , am I to assume it's about the same with the 270Win?
 
It's only a curiosity. I think WW cases have a reputation for thinner walls, resulting in very slightly more internal volume. This is not a big deal. If you like your Remington, you can keep your Remington.

No, really. the difference in case capacity is way down the list. I haven't shot 270 for quite a while, but the difference could come down to serviceability. Meaning, how many cycles do you get before trimming to length, split necks, enlarged primer pockets, etc. Cost is also a factor.

I would not decide to purchase a particular brand of cartridge brass based on internal volume. BB
 
I found 1 pc. of Win brass and it looks like the Win holds about 1.2grs more of RE22 over the Rem brass.
 
I've found a wide variance between brands. I load 40 gr H380 and 50 vmax in my 22-250 with win brass, it fills to the shoulder/neck junction. I had a few PMC brass in the mix and I couldn't even fit 39 grains in the case.
