Gunsmithing 6.5X47L minimum no turn chmaber

[Ackley Improved]

Aftera little info on the 6.5X47L chambers.

1. What size are your guys cutting for a minimum no turn chamber?
2. What are the loaded rounds measuring
3. What bushing are you using with no utrn brass.

I have decided to give the 308 a miss, and chamber for the 6.5X47L instead! Just ballistics!

Cheers

1. My reamer is supposedly tighter than SAAMI and the neck is 0.295", and I do no turning. The reamer is called 6.5 x 47 Whitley, you can find the print on 6mmBR.com.

2. With a 140 SMK seated the neck diameter is 0.289".

3. I use lee collet dies for this round as I had outstsanding luck with the lee collet die on another chamber starting with the 6.6 x 47 Lapua so I can not tell what bushing to use. I do try a bushing about 0.287.

Hope thsi helps,
