9.3

A heavy 223 is almost a recoiless rifle. :-)

For the sake of science, would you be kind enough to shoot a hunting weight medium caliber that you have previously sighted in offhand on the sled and comment on the POI, I don't have access to one or I would myself.

TIA

BTW That is not what I imagined we were discussing. The ones that I have seen are litraly a wooden contrivence (sled) to which the gun is affixed with clamps. It is weighted with, guess what, lead or sand. It slides along the grass under recoil. I have seen a version also with a spring that is pegged into the ground. A similer spring loaded carriage on rails is also what the London Proof House clamps your rifle into for testing.

Perhaps this device would allow free recoil and a POI consistant with offhand shooting. That would be very usefull for regulation.
