    Unless you take the plunge to the Weatherby calibers you can't really understand their value............if you never shoot beyond 250 yards you dont need one, so dont waste your money....once you pass 300 yards that extra 200-300 fps make all the difference in the world...I shoot 257 and 300 Weatherby..having moved way up from 243 and 30-06.......it gives you a whole new concept in shooting with a laser like trajectory.....as far as barrel life, that is all hype....barrels wear out when you shoot them after they get way hot.....only a fool would shoot enough out of my 300 to hurt the barrel.....so dont shoot prairie dogs with them and they will last a lifetime....duh? Also, the 257 has a kick like a 30-06, manageable for anyone, yet flat to 350 yards....so even if you can't judge distance, anyone can succeed with one, also, you can make 257 brass by just running new 7mm mag brass thru the die, they are 1/64 short but it makes zero difference in either accuracy or on the chrony.....if you take open country hunting seriously, you really need to step up to Weatherby.....duh?
