I shot in a metallic silhouette competition this morning with my 457 MTR. Targets are at 50 - 100 - 150 - 200 yards. We are allowed to use a front rest or bi-pod for everything but the 50 yd. chickens. I was using a Caldwell Rock BR but it's far too shaky when extended for the 200 yd. rams. Most guys were using bi-pods. How about a recommendation for a quality bi-pod that attaches to the front swivels on my MTR. I don't want cheap nor do I want something that looks like it was designed for the space shuttle. Thanks!!
