The phrase 'Jack of All Trades, Master of None' is the entire phrase, it was created some time during the late 19th Century, meant to be a derision of people who spent their time learning many skills well instead of sticking to one and mastering it. The extra bit; 'Better than a master of One' is a relatively new addition which, from what I and others have been able to find, did not exist prior to the 21st Century.
24:00 W R O N G! The closest thing we have to a bolter is the Mk19. Bolter shells are two-stage rocket-propelled grenades, first it fires like a normal bullet and then upon travelling a set distance the rocket motor starts.
I know the mg-42 training video Mike was talking about, on how US machine guns were better because they were far more accurate according to 'tests'. Man, if i wanted an accurate weapon, give me a scoped rifle; otherwise give me that long-range shotgun you have there Hans! Those poor green GI's that didn't know better than take those videos to heart... Edit: Be sure to check back onto Brandon Herrera's channel,. They actually have a slow motion Gyrojet video. Seeing those $200 rounds rocket through a ballistics gel block like the Apolo rocket towards the moon. 🚿👌
23:52 I don’t know if you’ve seen or reacted to it yet, but Brandon Herrera did a video not too long ago with *his* Gyrojet pistol, if you’re interested.
