Here's my .02. I think part of what's going on might be that the Orange dots (if they are on a white background) can be hard to "lock into" as opposed to superimposing the crosshairs on a target with grid lines. I always the Redfield precision sight in targets (or something equivalent) so that I can lock right in on the grid. I also use a heavy bag up front that really cradles the forearm and a rear bag (like the set-up pictured). I think the bipod might be the other piece of the puzzle. I totally agree with slapping the bipod on and verifying POI after the load is validated off the bag but I don't use a Bipod for testing purposes. Hope this adds to the discussion!
