I didn't see where I said any of that. All I am saying is with more than double the choices in bullets selection, higher BC bullets and more readily available components you cannot argue it is a handicap by going 257bob.So you're saying that if I'm using a 257 Bob, the bullets, if they happen to go straight which most of the obviously won't, that they'll bounce off everything from ground-squirrels to mule deer. If it shoots just as accurately, kills things just as dead, and is just as enjoyable to shoot plus being slightly more effective on larger game, what's the handicap?
Loaded with identical bullets the bob gets the edge in energy and fps BARELY. Loaded with the best of the choices available the 243 will leave the 257 in the dust ESPECIALLY when talking about longer than 400yds.There isn't enough of a difference between the two in actual function and effectiveness to really matter. The 257 has a slight edge on larger game, but that's it.
If the 25s were so great then you would see more of them. The reason you do not is they do nothing better and cannot compete with the 6mms and 6.5mms on the range or in the field. I seriously looked at getting a 25-06 until I compared it to a .260rem and it was obvious the 260 was clearly better in every aspect. Same with the bob vs the 243. While I respect CraigC and the wisdom he normally provides in this forum we will definitely not agree on this topic. But hey That's why there are so many calibers. Too each his own I guess. I hope the OP finds his rifle and is happy with it.
