I saved my money, for forever it seemed like, and I was able to get a Shiloh Hartford model chambered in 45-70... My next rifle will be another Shioloh and it will be in 45-90 caliber. Then, if I am fortunate, I will get anothe Hartford model in 45-110 caliber. I already have a quiet a bit of brass, for both of the anticipated calibers.
However, a friend of mine has a Uberti Sharps, in 45-70, which he loves. I have shot his Uberti and it performs well.
