6x47 Lapua Question

Hello, guys. I'm preparing for a 6x47 Lapua build and am interested in what size neck those of you who shoot this cartridge are using. I'm seeing chamber prints with necks from .269 up to .275.
I'm interested in shooting bullets no larger than 88 grains out of a 1 in 10 twist barrel for varmint hunting. Any information that anyone is willing to provide regarding acceptable freebore for these smaller weight bullets would also be greatly appreciated.

Thanks in advance for taking the time to provide input and share your knowledge.
