As far as range clout,
The .45-70 is just another lever action to most people, even casual gun people. Almost everybody thinks its another Winchester 30-30. You have to show them the cartridge and explain it, blow up a line of milk jugs before they "get it". The people that know it by sight and get the cool factor of an 1886 in .45-70 are uncommon,
Whereas,
The Uzi speaks for itself. Eeeeverybody knows what an uzi looks like and most have not seen one in person, even most hard-core gun people. It's not as slick or streamlined as most modern pcc's but it gets as much or more attention.
I reload for mine and it's very reliable with my loads. Clunky, blocky, and heavy as it is, it's a lot of fun at the range. Very little recoil, you can rattle off well aimed shots as fast as you can pull the trigger.
I'd like to get a railed plate for mine to install a red dot.
