22tcm vs 5.7x28:
5.7 is a PIA to reload. Cases cannot be tumbled (although I DID run some thru the SS pin tumbler and they ran fine). Not a good idea to strip the lacquer coating off the brass. though. So I wash them in a solution of Simple Groin. And you can't get new brass, so you're starting with someone else's stuff or just your empties which means you gotta buy the ammo to start with. I HATE buying ammo.
So you resize the brass. Need to set back that shoulder and it takes some lube and effort. Well that part is pretty much the same with the tcm. But many of the 5.7 primer pockets need to be reamed and ALL the brass needs to be trimmed, chamfered and deburred. This is a time consuming project and even though I have a big motorized trimmer the cases are really too small for that setup IMHO. So it's one by one with the Lee trimmer and motorized screwdriver.
Seating the primers isn't too tough once you ream the pockets.
I use 5.4gr of True Blue and V-Max BT bullets, 40gr. that combination works. Charging and seating are pretty routine. It's just they are so small and tempermental....and there are so many horror stories that you get scared a bit. But I had only 1 issue, and that was with a ProMag 30 round mag in the pistol. Two rounds caught on the feed lips or something and the bullets pushed into the case. But no other issue ever.
Just time consuming, and not for amateurs to reload.
