While I will second the quality of Shilo Sharps rifles, I certainly would not agree with getting a 45 100. I had a a 45-120 and it kicked like a mule. I shot it relatively little and sold it after a couple of years. My impression is that many of those who buy the 45-120s do so because they consider it the original buffalo caliber and after shooting their gun a few times end up having it rechambered to 45-70 or selling the gun .
While I think 45-70 is convenient to shoot, I also think there are several other calibers between 40 and 45 which are a lot more comfortable to shoot and still have enough knock down power to knock the silhouettes over. I think I already mentioned that I currently shoot a 38-56 with a fast twist barrel that allows me to use 300 grain slugs. Also a 44-77 which I am optimistic about working a load up for
