If you have access to a chronograph (or if you can borrow one from a friend) you might consider seeing how fast they are moving from your gun. Knowing that number, a simple call (or e-mail) to Corbon inquiring as to the "velocity floor" for expansion of that round should tell you if you can keep this load or if it's time to reconsider your options.
