I suspect it will require a 1 in 8 twist to stabilise .

 You could check by entering the bullet details into a twist calculator  (JBM) .

Length = 32.03 mm

Diameter =6.17 mm

Weight=6.67 grams 

G7=0.258

 As Snakeman pointed out you may well be at the barrels limit at the 85 to 95 grain bullets. Especially if they're the slippery sort .
