If you use the 45A contacts and AWG 10 wire, you either have to use the proper crimp tool or solder very carefully. The barrel of these contacts just barely fits in the shell, and won't if it's either distorted or has solder on the outside. If you don't have the crimp tool, just solder carefully and, if necessary, file off the excess. If you try to crimp it with the wrong tool, it will never fit. The smaller contacts aren't such a problem, but they won't work with AWG 10.
Aside from the extra time it takes, the only down side I can see to soldering is that the solder wicks up the wire a ways and makes it brittle, so you need to make sure the wire doesn't flex a lot near the connector. 73, Scott K9MA Scott Ellington Madison, Wisconsin USA On Mar 25, 2011, at 12:02 PM, George A.
