Looking for some insight from people shooting THIS bullet in a bolt gun. What twist are you running? I would like to run 75gr bthp as well. I think 8 twist Wpidl be ideal for flexibility.

8 twist runs them great. Anything slower like a 9 or 10 twist probably wont stabilize the 75s
My 9 twist will run the 77SMK but not the 75 BTHP or A max.
My rifle with 1-9 twist barrel shoots 77 gr SMK better than 75 gr OTM at 600 yards. At 100 yards it's not much difference.
I’ve ran the 50, 55, and 60gr VMAX bullets in 9 and 8 twist barrels. The 55gr liked both but seemed to group a bit better with the 9 twist. The 9 stabilized everything I put in it up to 77SMKs.
Never attempted it in a 7twist. The 50gr group size opened up in an 8 twist. This was a 5.56 chamber with a bit longer throat so it was dang near free bore before it hit the lands. I ultimately settled on 60gr VMAX since it seemed to be the least jump sensitive of all of them.

My 9 twist will stabilize 77SMK, 73ELDM, and 75BTHP but if I could pick and choose twist, I would go 8.
