Copy that on the F class bipods. Most of the composite stocks have an action bedding rail- usually aluminium- molded in to cinch the action down to. My Savage runs a rectangular portion of that aluminium extrusion forward to anchor the sling swivel. I wonder if its possible to advance that concept to have the hinge bolster for the bipod's legs machined out of a single piece of billet aluminium that is also the action bedding block? If it were one piece of aluminium from the tang of the action carried forward through the bipod hinge bolster it would eliminate all the problems with connections. The movement would be limited to the flex of the monoblock induced by whatever strain the rifle experienced. Not a new concept. The Art Deco Stream-liner Steam Locomotives had their frames with the steam cylinders cast in one piece to eliminate "weaving" of the metal structure. They did that to lighten, strengthen, and eliminate fatigue failures. Shed of its sand mold the frame looked like a forest of steel stumps from all the risers and reservoirs. Machined it was an elegant monolithic steel masterpiece.
Just thinking out loud.
The 375 Ruger is not my choice for a long range gun. I bought it for big bears (I call it my BB
and a big hammer at 1/4 mile plus. My next long range gun will be in 7mm RUM or 6.5 X 68 MS. Something overbore that will drive the new high BC hunting bullets now on the market to >3000fps.
Love to see you post a picture of your rig.
