I still have my RCBS Rock Chucker.
Until they invent a more rigid, accurate press, I'll keep it.
I have a Lee Turret Press.
Which GREATLY speeded things up when I cranked out 'Plinking' rounds.
Not quite as accurate as a Rock Chucker, but great for small runs when you are just loading a few new powder/bullet change samples to see how they run.
Caliber changes consist of new turret and shell case holder.
...Easy under 30 seconds.
For 'Production' I use a Dillon XL650 which I have about TWO MONTHS in the last two years 'Tinkering' on to get running,
It's always SOMETHING not quite right with that Dillon...
Changing Shell plates, feed ramps, feed inserts, case feeder nipples, ect. is EXHAUSTING if you aren't doing several at a time
(The reason the Lee Turret got mounted on the new bench)
And if you switch primer size when you change caliber,
It's dinking with the internal tube for the primers, pulling the primer assembly and changing the feeding disk, changing the primer punch under the ram head, ect.
Not to mention using primer pick up tubes for the correct size primer.
Busy work to get a full caliber change, but with enough accessories, it will load almost everything I shoot, which is saying something...
From large cases to small cases takes at least a half hour, if not more,
And that's only if you have run the caliber before and have the dies already set up, an extra powder charge thrower already set up, ect.

Dillon did not invent the modern Mini-Gun. General Electric did and most were manufactured in the 1960s. By 1975, manufacturing of spare parts ceased and by 1985 the parts were exhausted.
This is correct as far as I know, which is about '94 when I stopped working on them.
General Electric was contracted to build a modern 'Gatling Gun'.
Singer (sewing machine people) made a bunch of the small mechanical parts, while GE provided gear cases and electric motors, and was the overall contractor.
The first version was the GAU2,
Which is what you see the most of in movies and such.
It was much smaller/lighter weight than the later Dillon Areo 134/134A
Failure with the GAU2 was normally accredited to the guys running well past the cyclic rate of fire recommended, which was a maximum of 3,000 Rounds Per Minute,
The field troops found out very quickly how to burn almost 6,000 Rounds Per Minute, wearing the gun out and breaking parts.
(When someone is shooting at you, you crank up the cyclic rate of fire! We were glad to fix them...
When you break them in training, we get a little frustrated.)
There is nothing quite like the damage done when something breaks, jams up in something cycling 3,000+ rounds a minute, the breakage was often catastrophic.
The original parts contract was for 7 years, so anything we could get was left over from Viet-Nam or shortly after,
And it's strange getting parts in boxes marked
'Singer Sewing Machine Company'...
(which Singer hasn't made sewing machines for decades,
The name lives on, but Singer makes missile parts now.
The GAU series was supposed to be for special operations troops/aircraft,
But field grunts being who they were, mounted them on everything from tripods to trucks & boats just as fast as they could acquire them.
Following the lead from WWII convoy troops, the guys in Viet Nam built 'Gun Trucks' to support convoys,
The update in Viet Nam was the addition of 'Mini-Guns',
Which they used to great effect!
They can be found sticking out the side of the old 'Specter' (Spooky, Puff The Magic Dragon) propeller driven aircraft in various bore/caliber...
The bigger brothers of the little 7.62 GAU 2 & 134 have been built in 20mm M61 'Vulcan', 25mm GAU12 and even the big daddy of them all,
The 30mm GAU8/8A tank buster the Air Force built the A-10 'Warthog' jet airplane around.
The Navy has the Phalanx (M61 Vulcan 20x102mm) & GoalKeeper (30mm GAU8, GAU12U/GAU13A, 30x173mm)
Some are driven by electric motors, others driven by hydraulic motors.
I don't know if it's a myth or not,
But there was supposedly a 5.56mm version built also.
Never seen one, just heard the stories.
