I know that you will love the BLR (I only have three), but I believe that fate has smiled on you by sending you the .358. With the proper bullets, it should more than handle your bear problem(and deer and pests) as well or better than the .450. I think you will find the .358 a good bit more versatile, with better range. Also, you are not tied to a single supplier of brass. If the store is out of shells, a handloader could make .358's out of range scrap 7-08's or 308's, but not so with a .450. BOL
