Since you already have the #1 and want to try the game, bring it to a match and have fun. It isn't the best choice but that isn't really important until you decide whether you want to join the rest of us lunatics on a regular basis! If you make that choice after using your #1 at a couple of matches, by that time you'll have a pretty good idea of what you want.
If you don't have a scope on it now and want a silhouette scope, the most useful scope would be IMO a Leupold 6.5-20x40mm with target knobs. If you don't stay with silhouette, that's a little much -- but still pretty good -- for field use on a .270.
