I've used Lyman carbide for almost 30 years. Carbide definately require less force. I will say .44 mag was a bit of a chore on old RCBS Partner Press. Doing rifle rounds were like using exercise equipment. You didn't mention what press you are using but you will get a lot more leverage on the big ones. I eventually upgraded to a Hornady 007 which of Rock Chucker equiv. catagory, and I've been content ever since.
