I think I may have figured out why my bipod was causing vertical strings. When I looked at it this evening I noticed that the knob that locks the legs in the short position were not locked. On this Harris benchrest bipod the legs have a short position, a long position, and can be manually set between or adjust one leg for levelling. If the legs, while in the short position, were not locked I think it allowed the rifle to bounce when fired. If one leg was partially tightened it would cause a string that leaned to one side, like my string did. Does this sound reasonable? Jim |

Bipod mounted to a float tube, and the barrel floating? If so, then my guess is that you are not re-leveling the rifle, and maybe even putting input (pinning the rifle down) into it. Also, as you sure that the barrel nut is tight, and you are shooting for groups before the barrel over heats? |

With the bipod mounted to standard hand guards, you can flex the barrel. This is the problem you are having now, and as the barrel gets hotter, it will flex more. Until you get a float tube, you are better off just sand bagging under the hand guards as close to the receiver as you can for groups instead of using the bipod (less likely of flexing the barrel). |
