I started Bench Rest shooting in 1977. Back then Remington would pay $1000 to any winner who won using a stock 40X.
So 30 years of testing rifles on sand bags is a good standard.
About 20 years ago I started putting bipods on rifles and Contender pistols. My best friend and long time shooting partner ED spent a Summer with me two years ago. We shot a lot. I said in the last several years that I can prove that a bipod cuts 1/4 minute off my 100 yard average group size...compared to a rest and squeeze sand rear bag.
Ed looked at me like the priest in The Exorcist.
We got into an out of proportion debate. Time allowing that day on the range with his rifle....He proved it to himself in fact we stopped at a gun shop on the way home whereupon he bought a Harris for his 6.5 Ackley Improved.
