I built a Uberti 1885 30-30 into a 257 Roberts Ackley rimmed and made my own fore stock. I shot deer at 400 yards.
I got an 1885 this year that was reamed out from 45/60 to 45/70 in the 1930s. It is in terrible condition. The tang needs to be welded again. But it is shootable, just not long range accurate.
I will probably either do 25/35 or 25 Krag Ackley.
Just cause I have the reamers, dies, and brass.
The stocks I will just find some reproduction utility wood.
Per usual, I will design a rube goldberg custom scope mount.
It will be lucky to get hunted by 2016.
