Now I found the scope test!
Attachment 102743
This was made with my Eddy, using factory ammo. Free-floated barrel, bedded receiver and nocksform.
The scope mounting was one of those slightly flaky wedge-action types, fixed in place of the backsight, so as not to drill and tap the action.
As you can see, it has sub-MOA potential - 2 scope sighters and 3 out of 5 in the group almost form 1 hole. For the two other shots I have no explanation other than my PWF! A permanent scope mounting might provide better results, but I don't like making irreversible alterations to antique items.
