I've used a cinder block wrapped in a towel as a "bipod".I just paid $140 for my Harris that Ill use on my hunting rifle. I'm 59 years old and it will still be working perfectly long after I'm not. I'm building a NRL type hunting rifle that I'll also put a bipod on. I will not be putting a $500 bipod on it even IF its the best bipod ever made. I think the advent of YT, and PAID "non bias" YT reviews, are having too much influence of what is actually good and what is just expensive.
Shot very well.
Also use my old Army sleeping bag as a rest. It too works well!
I use "cheap" bipods because they use less room of the bench so I can put more of my crap on the bench.
