Ask any contractor friends for some old home building plans and use the back side of them.
The stick on dots or a Magic marker for making Xs to shoot at works fine and you cant beat the cost.
As for the spotting scope, certainly a new high end scope is a desirable thing to own for a serious shooter/hunter.
But what happens to many high end scopes when the owner dies or no longer needs it?
I can tell you what happens with many of them, they get sold for a fraction of the original cost on EBay.
In PA virtually all serious long range hunters use large binoculars mounted on tripods for glassing and shooting while hunting.
For about the last 40 years or even more, the vast majority have been using 2 spotting scopes mounted in machined adjustable brackets. Yet still today, even with all the great scope choices available, the most popular set in use by far is a pair of the older Bushnell 60mm objective Bushnell Spacemaster scopes. And you will find them on EBay in good clean condition for about $100 quite often.
I have bought Kowa TSN 77 mm scopes in mint condition for under $400.
