I'm not familar with that bullet but I have loaded up and shot some Ranch Dog 290 gr with Lil'Gun and found it very accurate as well as pretty much capable of stopping a pig or deer. I see he used several powders in his development which included not only the Lil'Gun but Accurate 1680, Winchester 296, Norma R123, and Hodgdon H110. Those would also probably work in your case also.
