45 Auto Rim

[rockquarry]

I used to shoot .45 AR out of my .45-70 Rolling Block Buffalo Rifle.

Haven’t seen one of those rounds in years.

How did that shoot with such a large difference in bullet diameters between the .45 AR and the .45-70? I have a Shiloh Sharps .45-70 but never thought about trying .45 AR ammo in it. Seems like accuracy would be very poor.

why would anyone want to do this?
