  The $^{24}$Mg($\alpha,\gamma$)$^{28}$Si reaction influences the production of
magnesium and silicon isotopes during carbon burning and is one of eight
reaction rates found to significantly impact the shape of calculated X-ray
burst light curves. The reaction rate is based on measured resonance strengths
and known properties of levels in $^{28}$Si. The
$^{24}$Mg($\alpha,\gamma$)$^{28}$Si reaction rate has been re-evaluated
including recent additional indirect data. The reaction rate is substantially
unchanged from previously calculated rates, especially at astrophysically
important temperatures. Increases in the reaction rate could occur at lower
temperatures due to as-yet unmeasured resonances but these increases have
little astrophysical impact. The $^{24}$Mg($\alpha,\gamma$)$^{28}$Si reaction
rate at temperatures relevant to carbon burning and Type I X-ray bursts is well
constrained by the available experimental data. This removes one reaction from
the list of eight previously found to be important for X-ray burst light curve
model-observation comparisons.
