If you try to make the rifle stand up by itself (on a flat surface like a floor) with the bottom (flat) part of the magazine as partially supporting the rifle, will it stay upright without any additional support?
Yes, my carcano will stand upright but my rifle does not have a two pound scope mounted off to the left side.
Do you have an accurate weight of your rifle (no scope)?
Edit: I believe that Robert Frazier testified that the rifle and scope weighed 8-pounds. Wikipedia lists that model rifle as weighing 7.5-pounds. Therefore the scope weighs 1/2-pound. Not two pounds as you claim.
