Wow (he slaps forehead) I totally forgot 405Win. I too, have a Winchester 1895 albeit a newer one. I almost took it to Afrika for lion; but my 470DR won out.

Years ago there was an article in one of the then popular gun magazines about the Pedersoli (Colt Pattern) Hammer Double rifle in 45-70. The author lengthen the chambers to 45-120. When I read that, I was in total LUST. I dont recall how it worked for him, all I remember is the pics of the Double Rifle with those long cases.....

I did a internet search last night for the 45 long cases just incase I ever make the leap. Theres a lot of options, at least a lot of listings; but very little currently in stock.
