For loading .455 I use a set of RCBS .45 ACP dies. This set has worked well using Dominion brand .455 brass, which I have been using for many years. I have not yet used any of the shorter .455 Fiochi brass, but it looks like good quality and one of these days I'll reload a box or two of that as well.
To get an idea of the strength of your Colt New Service, check out the various other rounds it was chambered for by Colt; 44 Russian, 45 Colt, 45 acp, etc. It is a fine old gun. As always, you must take care to setup your loading press with good lighting, have plenty of time to double check what you are doing and have no distractions!
