Re: Sinclair bipod shooting techniques
What works for me is that I took an old cutting board(caught hell from that when wife found out) and made a fairly slick surface for the skis to ride on. That way, wherever you shoot you have the same surface. I use an Edgewood rear bag packed fairly tight. Depending on your body type, you may have to raise the front board and rear rest with a board or similar underneath to get the position you want. When I get behind the rifle, the bipod is on the slick board in front and Edgewood in rear, I position the crosshairs on the target. The stock rides the back in the rear for your fine elevation position. I'm shooting a 308 so I want to pull the rifle in pretty tight to my shoulder and maintain a good, consistent cheekweld. When the rifle recoils, as long as my position is good behind the rifle, it recoils straight back. I've found that you really have to concentrate on follow through with the ski feet type bipods. In other words, make sure you ride the recoil til the end, keep your head down and practice good fundamentals. With a Harris, I preload it and the rifle hardly moves upon recoil. With the Sinclair, it's going to move some. Follow through is crucial. It takes a little longer to return to battery on the Sinclair, at least for me. I think using the slick board in front is a big improvement from trying to shoot off the mat or ground. It provides a consistent surface all the time from place to place.
I'm not sure if I answered your question. If you want more specifics, ask away and I'll try to answer more specifically.
Good Luck!
