This question has been asked on the forum but not (I think) in this section. I have both a 1:7.5 & 1:8 twist barrel on hand. I shoot mostly 105 vld's and sometimes the 105 hybrids. Will the 1:7.5 be better or worse or same for this application?
Benefits/disadvantages of 1:8 or 1:7.5 twist for 105's in Dasher

You can run them here:

You're looking for an SG of 1.5 or higher in your conditions (altitude, temperature, velocity, etc).
Below an SG of 1.5 you can still shoot good groups, but BC will be somewhat compromised.
Take care,
