I just got back up from the shop, bedding some guns, lapping and mounting and gluing scopes..... and I tried a little test. (I got guilty thinking my swishing the sword around analogy might seem flippant)
Big 30" live varmint barrel on a Rem 700. 1.250 shank for 3" then tapered to just over an inch at the muzzle. Dunno if it's 7lb but it's heavy. Wide open freefloat around the barrel and for once, some play in the recoil bedding...... this is one I did back when I taped the front and sides of the lugs.
I installed the front action screw leaving the back or tang screw out.
Now, when the front screw is loosened and tightened the barrel falls down into the forend channel.....the rear tang lifts. And what I'm saying is ON THE REM700 it doesn't take much pressure to suck the screw down, in fact with an inletting screw in place you can pull it down with your fingers.
One of the things that became apparent to me while fiddling with this is, this is a good design! Some actions, like the Weatherby's have the front screw actually in the lug, ALL of the bending forces are absorbed by the action rails and body.
So, I stand by my contention that there's no reason to bed the barrel on a Rem700 or modern custom action. Your Borden is wikkid fine....
And I realized another thing. I hadn't really thought about this for 20+yrs, back when I was asking the same question! And guys like Jim Borden were telling me "don't bed the barrel"
Nowadays I'm more worried about other forces, resistance to uplift, feedback and stock flex thru the magazine area, I hadn't taken the time to think this thru for quite some time.
