I like and use the Bob, I have two a Winchester model 70 Super Grade Featherweight 50th anniversary Cabela's edition, and a Pre 64 Model 70 standard. I have one other quarter bore and that is a 257 Weatherby in a Mk V. Never used the Bobs on Elk but I have shot Elk with the 257 Weatherby using 115 grain Nosler Partitions. I have no complaints on any of the three.
