Blain, thanks for your nice comment. I liked the way this caliber shoots and behaves. I didn't origianlly think I would like it compared to the 45/70, but it hits with authority and holds it's energy well, further out than the 45/70. Not having used it on live game, I can't comment on the killing power, but I suspect it will do just fine! Send me a PM with some of your favorite loads. We have shot several different loads in this one and all seem to regulate very well. I am curious to know what you used in yours and how long the barrels are. These are 24 inch with a one in 20 twist.
