I would go with a Ruger or if you can Find a Dan Wesson 44 or 41 Mag. The Smith and Wesson 44 Mags will not stand up to full power 44 mag loads for very long. I shot Hand Gun Steel silhoutte for ten years and saw many S&W shoot apart. You can,t hurt a Ruger Black Hawk, Red Hawk or Dan Wessons unless you really try hard. The Smith is a smoother gun and shoot great as long as they last but that ain,t long. I have had a lot of Smiths and I shoot reduced loads 95 percent of the time. I would go with a good 2x7 power scope and after some practice a 100 yard shot should be doable.
