If I wanted a 45-90 to shoot the Quigley Match...
Would it be easier/more cost effective to
A: Sell all my 38-55 brass, dies, mold and rebarrel my 1885 High Wall to a 45-90 (barrel and extractor are the only things that need to be swapped)
B: Sell my whole 38-55 setup and buy a brand new rifle
C: Become rich enough to buy a Sharps like everyone else uses and stop using a high wall
