The 6mmbr is my favorites for a no muss no fuss accurate cartridge. All of mine have been rifles though...
My current is a 1-12 twist Remington, slower twist and a shorter throat, 80 gr bullets shoot well.
My previous barrels have been 1-10, 1-8, 1-10, 1-12
Creeker steered you to the right place for cartridge information.

I don't think your barrel is throated long enough for factory Norma ammo.

I have owned 7x30 Waters in a contender and your 6mmBR Encore is intriguing!

PM incoming.
