I use the Hornady 250 Monoflex in my 450 Rigby & 458 Lott, a bit faster than the 45-70 to be fair
I use them to keep the projectile weight down to reduce recoil & increase velocity for flatter mid range performance
Being a solid copper projectile they hang together, give great penetration & amazing terminal performance
I bet that would be awesome in 45-70!!!
