I use this to remove crimps

It is more or less a knock off of the original Dillon swager.
These tools are fast. I go from a full bucket of cases that need it on my left to an empty bucket of the ones i swaged on the right.
I use this to trim the brass

It is not without problems though.... Since it trims off of head space your die needs to be permanently set or you will get different trim length numbers. Also if brass pieces accumulate (they often do..) you will get sometimes large variations in trim length.
$200 and something already.
If you are picking up your buddies brass and it has a NATO emblem on it, it is likely crimped. With the exception that it could be re manufactured.
If that is the case, throw it into the garbage. Who knows what its been through.....
For me, LC NATO brass only. And only if i bought it as factory ammo, shot it from my rifle and kept track of its history.
Reloading is to much work for lackluster performance.
IMO....
Everybody is different.
