Whitworth,
Thanks for the clarification as I only heard what I wanted to hear I am sure. The 500 Linebaugh does weigh less than the 500 S&W magnum. It does have a larger hole in the barrel and the cylinder-charging holes. But pressure does cause recoil impulse and higher pressure creates snappier recoil. Jack Huntington related that the 500 Maximum has larger holes in the cylinder and barrel so it lightens the revolver enough to cause recoil velocity to make the ERH loosen regularly.He puts two or three deadman posts on the 500 Maximum to combat it.
I edited my earlier post to reflect your need for proper record keeping on this site. Integrity is JOB ONE!!!
