  We have performed a deep Chandra observation of Galactic Type Ia supernova
remnant G299.2-2.9. Here we report the initial results from our imaging and
spectral analysis. The observed abundance ratios of the central ejecta are in
good agreement with those predicted by delayed-detonation Type Ia supernovae
models. We reveal inhomogeneous spatial and spectral structures of metal-rich
ejecta in G299.2-2.9. The Fe/Si abundance ratio in the northern part of the
central ejecta is higher than that in the southern part. An elongation of
ejecta material extends out to the western outermost boundary of the remnant.
In this western elongation, both the Si and Fe are enriched with a similar
abundance ratio to that in the southern part of the central nebula. These
structured distributions of metal-rich ejecta material suggest that this Type
Ia supernova might have undergone a significantly asymmetric explosion and/or
has been expanding into a structured medium.
