We present moderately deep (125 ks) {\it XMM-Newton} observations ofsupernova remnant G330.2$+$1.0. This remnant is one of only a few known thatfall into "synchrotron-dominated" category, with the emission almost entirelydominated by a nonthermal continuum. Previous X-ray observations could onlycharacterize the spectra of a few regions. Here, we examine the spectra fromfourteen regions surrounding the entire rim, finding that the spectralproperties of the nonthermal emission do not vary significantly in anysystematic way from one part of the forward shock to another, unlike severalother remnants of this class. We confirm earlier findings that the power-lawindex, $\Gamma$, ranges from about 2.1-2.5, while the absorbing column densityis generally between 2.0-2.6 $\times 10^{22}$ cm$^{-2}$. Fits with the {\itsrcut} model find values of the roll-off frequency in the range of 10$^{17.1} -10^{17.5}$ Hz, implying energies of accelerated electrons of $\sim 100$ TeV.These values imply a high shock velocity of $\sim 4600$ km s$^{-1}$, favoring ayoung age of the remnant. Diffuse emission from the interior is nonthermal inorigin as well, and fits to these regions yield similar values to those alongthe rim, also implying a young age. Thermal emission is present in the east,and the spectrum is consistent with a $\sim 650$ km s$^{-1}$ shock waveencountering interstellar or circumstellar material with a density of $\sim 1$cm$^{-3}$.
