Fotis,
I forgot to mention that the Modern Miroku 1886 45-90 has by design ALWAYS used 45-70 ammo with ease and accuracy. It is my understanding that was a requirement and selling point.
In fact, most of the deer, Pronghorn, and small exotic game my 1886 has taken was with factory Winchester 45-70 300 grain ammo at 1850 fps. Those bullets are Nosler PP and from 45-90 load at 2200 fps kill Leopard in Afrika as well as factory load at 1850 does deer here in Texas.
