[cc737]

I am starting a new rifle build using a MDT chassis in 6mm Creedmoor will be using for F-Class, Open
I have been shooting a 6BR using 105gr with a 1 in 8 twist
Which barrel twist are you finding works for accuarcy using 105gr but mostly interested in 109 to 115gr
weight bullets.
I was thinking of either 1 in 7 or 1 in 7.5
Your thoughts Thanks

Check the Berger website...there is a twist rate stability calculator. 7.5 should be fine.

My 6 creed is a 1:7 and I shoot 108 eld and 115 RDF. No stability issues that I've encountered. Both loads have been trued to 1000 yards. Waiting for the snow to go away to see how they do further

I have shot tons of 115 through a 7.5, good to go.

I've also shot tons of 110s and 115s trough a 7.5tw and it's fine.
