My 147’s measure 1.435”, if you wanna punch that in to your calculator.

In my home weather (27.90/60), the SG is 1.42 at 2675 fps in a 8.66 twist.

i don’t have the rifle or bullets yet. purchase is hinging on this question. apparently mauser thought 1in8.66 over 1in8 was a good idea 🤦‍♂️ marginally stable is what i’m getting in that calculator
