Reprojection using GRASS: import into a new location, reproject from new location into target location with v.proj. If the shapefile holds polygons, I would strongly advice against using ogr2ogr for reprojection because (non-topological) ogr2ogr will likely create small overlapping polygons and small gaps between originally adjacent polygons.
