Ran across this barely looked at YouTube video from 7 years ago. I just tried it on a Magpul PMAG 20 round magazine. Got to admit it was really easy.
Anybody else use this technique? If so, any feedback, magazine damage, etc.?
Only 1 minute long, but action really starts at ~40 seconds in:
As soon as I saw all of them laying on the table like that, I saw it coming.
An interesting way. I’d rather load by hand since I usually pull from the box and pre-load all my mags. If out of the range on a table, the table usually isn’t level or has some debris which I dont accidentally want to get in my mag.
That is cool! I wished it were quieter, everytime I practice I hear “That better not scratch the table!” 
I’ve never seen anyone do that before. I hand loaded my mags until I stumbled upon RRS speed loaders. I recommend them. 
Damnit…I actually just got back from the range and my hands and fingers are beat from all the loading…this will work real good as i use an old foldable felt poker table top when i have em’ laid out
Dang! This video is on their site:
I may need this!!!
Just saw the video @Dawn posted - I might have to build one of those!
edit: @ $36/each it doesn’t make sense to build my own.
The price wasn’t bad. I opted to customize so mine was a little more. No more hand loading… Thumbs rejoice!
