I have 2 frames and several barrels. I did a lot of Silhouette shooting back in the day when I could still see relatively good. Now most of my barrels wear scopes and are used for informal target shooting and hunting. A few of my barrels will outshoot many rifles I own...Accuracy is the name of the game with the Contender platform. My favorite barrel is the 7x30 Waters, it's a tack driver. My very first time out to the long range Silhouette matches I shot a 36x40 with it. I've also taken many head of big game with it, it's a keeper.
