You can get the job done with a 257 wthby. A lot of elk have been taken with a 243. Having said that, the 257 has about the same ballistics as the 270 win and most folks I know don't recomend anything but a double lung shot on an elk with a 270...no shoulder shot... it's very risky. So I agree with the sentiment that shot placement is critical with that cartridge. As for berger vs tsx, it's true that a well placed berger will do massive damage, but once again you have less room for error than with a tsx and I personally would not use a berger for a close (less than 500-600 shot). And I wouldn't take 500 yd plus shot with a 270 or less on an elk.
My experience with elk was a big bull taken with a 7mmRM, 160 gr partition @ 15 yds, so no comparison.
I think a better cartridge would be any of the 7mm mags or 300 or 338. A lot more flexabillity with these.
