I have two 100rd boxes of this:
Remington Reloading Brass 260 Remington
Edit: While mine is Remington brand, are you certain you need actual Remington branded brass? (Not just .260 Remington brass?) I haven't been around custom rifles much, but I haven't heard of a rifle being chambered where it could only take a single company's brass.
If I go with say Lapua, I would have to turn the necks down as they are thicker.. His reamer is setup for the Remington brand stuff.

Lapua 260 brass does in fact have a slightly thicker neck than RP 260 brass, and it is completely logical that an early 260 reamer setup as a tight no-turn neck for RP brass (all that was out for a while) requires neck turning on the thicker Lapua brass.
Lots of folks found this out the hard way when Lapua introduced 260 brass 3 or so years ago.
