I guess for me it is mainly just to add a big bore to my hunting selection. As I think I have said here before, I have a .22Hornet, a .303 smle sporter and Tika T3 .300 WSM. I do already have another 45/70 but that is in a replica Sharps topped with a (I think) Navy Arms 4 pwr x 24" brass scope. The Sharps is great for playing with but not really practical for dragging round the bush chasing Sambar deer. I have also owned a Ruger #3 carbine in 45/70 which I keep trying to buy back and if I can ever
talk the present owner into parting with it, that WILL become a 450 Alaskan. If I do end up with a Baikal DR in 45/70, I fully realise that this is not a rifle that you can push the envelope with the loads, but staying within the pressure constraints using 350Gr proectiles makes a pretty potent relatively short range Sambar rifle for heavy bush country.

So in answer to 9ThreeXFifty7, why not? Ps:I also previously had an 8 x 57 Mauser and loved it.

All the best, Ian.
