Will a regular 700 long action (magnum, non ultra mag) accommodate a 28 Nosler or do you have to use a custom?
 
Cast, depends on what freebore your reamer has. Mine is .180” saami length freebore and I can fit 180 & 195 in the factory ultra mag box a 3.65”. If you have longer freebore you can install a longer Wyatt’s box to give you more room.

And yes you can use a regular magnum action but the feel rails have to be slightly opened up. I open them up with a file by hand and keep checking until the case fits through the feed rails.
 
I've chambered a few on regular magnum long actions. Like mentioned above, you have to SLIGHTLY open the feed rails. My reamer puts the bullets out there so I always used an extended mag box or longer mags in a chassis build
