***2. The tubular magazines of lever guns are not safe with pointed bullets. Think about it. :-) ***
I believe Remington developed a tubular rifle with a spiral indentation around the magazine which offset the bullet tip from the primer on the cartridge in front of it. I also believe some foreign nation used the tube magazine in a military rifle with the same spiral grove set up.
Can’t remember the names of them.
I believe that the Russian Army bought a tube magazine fed bolt action, designed by Hiram Berdan, after the Civil war.
The pointed "spitzer" bullet developed by Mauser in 7.92 sold to the Spanish for of the 1898 War changed everything for the American military. The .30-06 Springfield was a Mauser in all but name.
