We make detailed comparisons between the Halo Beaming Model (HBM) and data from the 3rd BATSE catalog, considering both the spatial and intensity distributions. The effects of a luminosity function are also discussed. In the context of this model, we find that the sampling depth of BATSE is {approximately}160kpc and the burst peak luminosity is {approximately}10{sup 40}erg/s. The distinctive anisotropies predicted by HBM are inconsistent with the 3B data at the 2{sigma} level, (i.e., HBM can not be ruled out at the 2{sigma} level). Future observations will be capable of placing more stringent limits. We emphasize that GRB sources born in M31 are almost entirely undetectable by BATSE in this model. We briefly discuss the energy budgets for the bursters and the mechanism of spindown alignment. {copyright} {ital 1996 American Institute of Physics.}
