So Im wanting to start F class open and off the bench Ive been using a baldeagle front rest and proteckor rear bag. It shoots great. Well today for the hell of it I put a harris bipod on and it actually shot slightly better. Which really shocked me Ive never had a good experience with a bipod and concrete bench. I used to have a centershot bipod and I sold it now im kicking myself for that. Anyhow, Im considering a duplin bipod. Does anyone here shoot with one? Is it " stiffer" than the centershot? Thanks
