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.
Anyone try a 7 twist with the light bullets too. Such as the 50gr vmax?
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.

I didn’t know they made a 60gr vmax.
My 7.7 T 223ai loves 53vmax at 3680
I can’t find them anywhere.
My 9 twist will stabilize 77SMK, 73ELDM, and 75BTHP but if I could pick and choose twist, I would go 8.
Can you find 55s anywhere?
I found some 50gr. But only 400
