I used a Browning 86 reproduction and killed two bulls with it.Don't know if they are still available,but I think they were 405 gr Remington ,with 3031 powder.

I don't know about distance, I killed both of those bulls within 25 yards. I gave it up because it was too heavy to lug around. Keep them slugs heavy

If God wanted you to walk and carry things on your back, He would not have invented stirrups and pack saddles
