Re: shooting rest for hunting
Thats not entirely correct. Free floated or not will not matter. It's more about how the rifle recoils. Using a bipod you can change your point of impact in several different ways. What you rest the bipod on makes a difference you get a little more bounce off of packed soil than you would off of tilled ground, and even more still off of concrete or the hood/bed of a truck. Also how you load the bipod (put the legs on the ground and pull back or push forward) will make a difference.
Some of these things make a big difference others not so much. Try a few different things and see what works. Mostly I think like everything else in shooting the trick is to be consistent.
Ignorance can be treated with education, sadly there is no cure for stupidity.
