Roll crimps usually have a lower pressure if you don't go over board with a real deep crimp. There is a large range of load data for all shells [ Federal ] - I'm not sure of which one you're talking about. If it's a low pressure load to start with, then it's probably good to use. The Mec short kit would be ok - you just have to make sure there's enough room after the shot is added to still get a good crimp. Look and measure the shells you're loading now to get an idea of what you'll need.
