We present a novel mechanism by which the isotopic compositions of SiC X grains are altered via interaction with reverse shocks in Type II supernovae. Three epochs of reverse shocks are important to the condensation and subsequent history of these grains. Using a 1-D model of a 25Msun supernova, we show that the first reverse shock creates a dense shell of Si and C near 106s, which facilitates the condensation of SiC. Subsequent reverse shocks from the circumstellar medium and the ISM, which occur near 108s and 1010s, propel the grain rapidly forward through decelerated gas of varying isotopic composition, causing implantation and sputtering by the overlying material.
