I too have only done the 2-AWg and 4-AWG ANCOR brand cables with excellent results.. This is using my MIC-70 8-Ton Hand Crimper I have had since 2009.

I would almost start worrying about my hand crimper start squirting oil on those larger size cables...
I don't think my 8-ton capacity model is large enough for those larger cable sizes even tho it comes with the die's for them...
At my work sites back in the day the 6-0 cables used a hugh tool to crimp them... Was a two person operation...
My 220Ah to 440Ah capacity battery banks will do me just fine using 2AWG and 4AWG size cables using my 60A DC Current PD9260C converter/charger for charging batteries. Using my clamp-on Sears AMPMETER I usually see DC current around 52-55AMPS of DC Current being pulled at the 14.4VDC DC Voltage charging modes... I also use this clamp-on AMPMETER to see the equal balance of DC Current going to the multiple battery connections when I am in charging mode. Great test meter to have around my battery banks...
