Let's all take a trip back to the late 1970s and early 1980s.  This was the time of punk.  This was the time of despair.   Punk was all about minimalism; strip everything down to a few chords, wear

Stechkin's Abakan (TKB-0146). https://www.kalashnikov.ru/abakan-stechkina-avtomat-stechkina-tkb-0146/        Bullpup, system of "recoil impulse shifted in time", 2-stage

So what, my 5.56 rounds are groundbreaking too if I shoot the dirt.

But they're SO damn iconic looking!

 

(I'm talking about the standard GI model of course)

At my peak I had four 1911's, all were GI "beaters".  For a time, they were not overpriced.  

 

I had a 1913 SA M1911 for a long time. I very much regret selling it.  I still have a '44 Colt I carry semi-frequently. 

 

Stoppages were almost always mag related. 

A simple fix, it involved a large hammer or a bench vise. 

Crush the offending mag.

 

never had any issues with known good mags, and serviceable ammo.

That's a good point.  The only issue with a semi-rim is that it necessitates the use of a new bolt face for the AGL variant.

 

Maybe it would have made more sense to use 23x152mmB ammunition as the starting point.


It is conceivable that both the rimless and semi-rimmed cartridges could work with a breechface sized for the semi-rim.

      There are many who feel that the 5.56 NATO is a superlative rifle round. Much has been said about larger alternatives to 5.56, such as various 6.5mm and 6.8mm rounds among others. Less has been said about smaller rounds. Off the top of my head, I can recall that there was a German 4.6x36mm round, used in the HK36, and the British 4.85x49mm round. Neither of these rounds managed to gain widespread acceptance. My knowledge of the voodoo that is ballistics is somewhat limited, so I'm uncertain as to whether these failures were caused by flaws with the rounds themselves, or because they were below some lower limit of effective bullet size, beyond which performance decreases rapidly. Could we see a resurgence of these concepts in the future, or do they represent an evolutionary dead-end?
