New BBL arrived

I have a 27" Brux bbl that arrived from BRUX . Do I have enough for a 26" bbl after gunsmith chambers,threads and fits the bbl to my action ?
 
The smith wants me to bring him some dummy rounds of the bullets i want to shoot. In the Hornady book it list 2.350 for C.O.L of 55g and 60 gr V-Max bullet . 2.390 for 68gr BTHP and 2.490 for 75gr A-Max. Isn't there a happy medium he can throat it for this bullet range ? 22/250 8" twist .....

Load the bullets you want to shoot in a case. Keep the pressure ring in front of the neck shoulder junction. That helps keep the pressure down and helps avoid donuts. Matt

As far as length is concerned , it depends on how your smith and you set your standards and what checks he does before he proceeds fitting it . Borescope , slug check runout , check bore dimensions at many points , etc.

I loaded 3 different bullets 60gr V-max 60 gr Nosler BT and Sierra 69gr HPBT all with the pressure in front of neck shoulder junction .
