Lager,
My bipods all mount to a double duty sling QD stud, and these studs are readily available in many different styles and combinations. So there are lots of ways to mount the studs. I've probably tired them all and found what I think works best on the Contenders for me.
How I install the QD studs (and with which type of stud) depends on the length of the forend and where I want the bipod on the forend. So the stud is either installed directly to the forend itself where I want it, or a stud is simply used to mount the forend to the barrel bar if that location works best for that configuration of barrel and stock set. Usually that means carbine and target length forends get the stud mounted directly to them and the shorter forends are mounted on the barrel with a stud. All of my forends (factory, custom and Pachy) are mounted with Bullberry hanger bars BTW, so they are all single hole mounted.
For those studs mounted right to the forend itself I don't use the wood screw type studs but rather the machine screw - hex nut type, drill and countersink the nut in the barrel channel to install. I use a 10-32 thread stud cut to length when being used in place of forend mounting screws. With the later you might need to use a shim to have the stud lined up correctly when tight. They are easy to make out of many kinds of materials and so they stay on the stud when it's removed. The bipod stud does not have to be overly tight and the bipod will align it if off a little when you tighten it to the stud.
HTH
YMMV
