HI ,
I shoot 45-90 Sharps,
use a set of RCBS 45-70 dies which came with the rifle, work great, pin screws out , no problem,
bought a set of 45-90s never used them,
sold on here,
also shoot a 11.7x56 Rolling Block,
use Lee 45-70 dies,
change the pin for a universal decapper pin, longer.
set to length, away you go,
hope this helps,
T
