Lyman actually makes one that does the same thing, but by hand.

Same with Hornady

Redding, they even mention chucking it up in a drill

Spend a little, spend a lot, Work smarter, Work harder.
Your choice :)
 
I have the lyman one but its the 6 bit aluminium handled one. I rather work smart than hard (now that is, I used to be a plumber).

Very cool, another that has seen the light that busting your nut is not the best way to earn a living LOL

Now I am a senior tech for the 2nd largest commerce site in the world, 2nd to alibaba that is and that is only because China has a big freakin' population and that is a closed market.
Give us time, we will take them :)
 
Both methods work. Since I've only swaged a grand total of 6, yes count 'em 6 pieces of 5.56 brass, I'm really not in a position to say that one method is better than the other. But the ones that I did, the primers popped in just fine.
 
Im headed to WSS to pick one up today. $46.74. Im still going to compare the shell holders.. But I think I know what the problem was.... User Error. I feel pretty embarssed for making such a rookie mistake.

I'd like to know what was the problem.

Crimped primers. I guess my google-fu needs work, I could only find discussions about Aguila ammo on US sites, they all said non-milspex ammo so no sealed bullets/primers or crimped brass.

I thought crimped brass would have little diamonds like LC 7.62 ive seen has. Instead it's just a circle crimp.
