Would like your opinions and experiences with Bi-Pod use. Recently I tried using a Harris non swivel 9-13" Bi-Pod on a Parker-Hale 1200C that has the normal factory bedding so the barrel is not free floated and it simply will not shoot with any sort of precision off the Bi-Pod. I tried it again yesterday off the bench at the range and with the Bi-Pod fitted and three shots spread over 6" wide yet remove the Bi-Pod and use a bag rest it produces a three shot group of under 1". I am not yet convinced that this rifle does not have a basic bedding problem as I am certain it should produce tighter grouping than this however the difference is rather dramatic.
Meanwhile I have tried the same Bi-Pod on another rifle that does have a free floated barrel and it shoots with similar precision to when just rested on a bag. I have to check carefully the difference in POI when it's shot in different positions. Off the Bi-Pod, off a bag rest and off the stick.
Later to further this experiment I will also try the Bi-Pod on another Parker-Hale rifle this time an 1100 Lwt in .308 which shows excellent grouping off a bag but as yet it's never been tried off the Bi-Pod partly because the Licensing people in their wisdom saw fit to list it as collection only and not for shooting and refused to swop it with another rifle that is listed for shooting why I have no idea.
