I was wondering if I could use bipods on a stockade prairie dog stock and savage 12fv? I was thinking of the br 6-9 " ones I tried the tall ones on a hogue stocked model 70 in 7 rm and it shot a 4 " group at 100 yds couldn't hit anything it also happened on a factory stocked 17 hmr from savage.Am I correct in assuming these shot so poor because the stock was flexing to much?Also would I have this problem on a stockade?
