257AI Freebore Question

[ringer]

For those running a 1:10” 257AI, how much freebore did you go with?

Id like to be able to seat 110 Accubonds/120 Partitions where the boattail is at or near the neck/shoulder junction of the case, or at least have the option to do this.

I'll check my reamer tomorrow.
Laying in bed right now.
4:45am comes early!

@ringer,

Sorry I didn't get back yesterday.
Evening got busy after work.

So, I have a PT&G reamer.
#PTG-10939-F-SCR
Unfortunately it doesn't list the freebore on the reamer.
But they have the drawing on the website.
From what I can make of it, it looks like the freebore is 0.084".

I'm loading everything from 75gr Sierra HP Varmint through the 120gr Sierra BTHP GameKing (the longest bullet that I have).
All have shot well.

Hope this helps!!
