Engine49guy beat me to it. Reduced loads was mentioned earlier in the thread, and the 460 has 2 loads pre-programmed as reduced loads. One of those loads you already shoot, the 454 Casull. 45LC also shoots well from the 460 at reduced cost vs the big boomers. Only consideration when shooting the shorter cases is to clean the cylinder routinely so there is no difficulty when chambering the longer cases from lead build up or powder ring.
