Hey Matt,
For a "10", all that you must do is break the ten ring line !
For an "X", your shot must be within the 10 ring line, totally within the line, not breaking it in any way.
In the "STEROID 15" RIFLE MATCH, an "X" is scored "11" POINTS. Good Luck buddy !
I hope this helps you, and WELCOME to the Target Shooting Matches !!!!!!
Bill
