Just an update for you all. I did end up buying the Renegade .54 and will keep you all up to date on my progress with it. Again in an attempt to answer the question of why try to shoot sabots the simple answer is a shorter learning curve. While I love to hunt and shoot I am very busy with my family, career and other interests. It has become apparent though that the best road to go down is a PRB and am looking forward to the challenge. Thank you all for your input, it's been a great help!
