Ditto to Arathols post!! If you're going to hunt off a bench rest, be prepared to haul it around in the field. NOT!! Springers are just too sensitive and tempramental to exact the same POI with two different holds. From my experience, I get it close from a picnic table, then tweek the kill zone as needed off-hand. To maintain consistant and acceptable groupings, set your range (zero) at a constant,... Ex: like 25 yards, and learn to adjust your shots at 20 and 30 yards. Mil-dot scopes really help out a lot in compensating over or under holds for farther or closer shots. But like stated before,...Practice, practice, practice!!!! I rarely if ever use a rest when hunting,.... why?,....because with patiences, I let the game come into my "field of fire". Off balanced, hurried, un-disiplined, and fatigued shots rarely take game in an efficient manner. Precision plinking as I call it, from different distances, target elevations, and target sizes is the best way to practice. No quary will ever set itself at the exact distance to your zero scope set up anyways. In all fairness, I rarely try a shot much passed 40 yards. And like Jeff says, if it were easy, it would be shopping. Be Patient and Practice Often. A Starlings death depends on it!!!! LOL's, tjk
