Investing the money in a proper crimp tool helps a LOT with these fiddly little buggers. I've got a nice set of interchangeable crimp dies that go with one of two different sized crimpers, ( Its from the same ODM/manufacturer as this tool set https://www.altronics.com.au/p/t2177-crimptool-ratchet-multi-connector-universal-kit/ https://www.altronics.com.au/p/t2177-crimptool-ratchet-multi..., I just collected my own set from several different stores because I wanted a different set of crimp dies) and while I can crimp right down to these sorts of small connectors... the moment I have any problems or it doesn't crimp right first time I'll put down my big crimp tool, and swap over to the little crimp tool I have thats specific for these darn things, pretty sure its this one, https://www.altronics.com.au/p/t1537-crimptool-telephone-terminal-20-28-awg/ https://www.altronics.com.au/p/t1537-crimptool-telephone-ter..., I've had it so long I've forgotten which model it is. While having good tools helps, they are still a PITA, just no longer a RPITA.
