For a .262 chamber neck, loaded neck diameters could measure .261 if chosen.
In that example, the bushing .002" smaller(recommended) is .259".
.262 is not very common with 6br.
I get the feeling you don't understand this well enough though.
Tight neck chambers are managed with more advanced reloading than common. You can tell by the sentiment in replies right here that some are afraid of tighter clearances, and/or advanced reloading.
It's just not something you can take a big jump into with success.
