I don't think you need a one and eight twist although I do not have a 180 VLD on this chart similar bullets seem to require at least a one and 11 twist rateI know the twist needs to be 1-8 however I have a factory Sendaro that still shoots 1/2" at 200 yds using nosler 160 AB. Everything is DRT. But would like to try the 180 VLD and see what this rifle will accomplish...... PLEASE SHARE LOAD SPECIFICS, I will work up after I confirm data.
