I have a Remington 700 ultra mag action and I would like to build a 338 Edge, I can order a barrel here in Canada, which twist is the better for 285 and 300 gr bullets, 1:9, 1:9.5 or 1:10? And for barrel contour any advice?

The standard twist recommendation is 1:10", however, "IIWY", I'd go with 1:9" on a 26-28" with .750" at the muzzle as min, would prefer .830"; but that's just me. Bullet manufacturer's like Hammer Bullets is recommending 1:9" for the 285s >>> https://hammerbullets.com/product/338-cal-285g-hammer-hunter/

Good luck on your build.

I agree with Ed.
I would go as heavy as you can on the barrel. When you get into the big heavy 338 bullets, the tourque that's applied to the barrel as it travels down the barrel will affect accuracy and harmonics.. I would bed the entire action, and do a solid bed in the recoil lug region with the exception of the bottom.
 
My Edge has a Barlien 9.5

So far it shoots everything well enough. Designed to shoot Hornady 285s, BTHP, A-MAX and soon ELD-M. It has done well with pretty much everything though.

I have but have not tried the "heavy" +260 copper/mono-metal even though I have lots and lots of them.

IIWM 9 or 9.5 10 is for 250 and smaller. Yes, I know a 10tw will shoot 300 jacketed just fine.
