Bottom line up front, there is no way for Ballistic Coefficient (BC) to practically affect accuracy at short range, meaning 100 yards, for modern centerfire rifles.
High BC bullets which tend to be long and heavy for caliber, requiring fast twist and generating more recoil are often less precise, meaning they shoot bigger groups compared to lower BC bullets. The lower BC bullets tend to be lighter, faster, generate less recoil and can be fired with slower twist rates which all aid in better precision, but do nothing for accuracy.
Recalling the definition of accuracy being how centered your group is on your intended aim point, there’s simply no mechanism for BC to affect this at close range. Short range accuracy is almost completely determined by your rifle being well assembled and your scopes ability to hold zero.
