So if you have every Weatherby caliber from 224 to 340 you would consider this as having a problem? lol
257 is my all time favorite and will be till the day I die. Get one you'll love it, if you roll your own remember the bullet selection isn't' what the 6.5's or many others offer but plenty of premium bullets out there that do the deed just fine.
I have a deluxe and backcountry in 6.5-300. I would say 270 as far as effectiveness for medium sized game would be close to it's performance but a solid choice as well. I shoot 130 grain scirocco's in 6.5-300, RPM and 270 - I do have a ruger 1 in 270bee that shoots 150 grain a-frames nice brush buster round! LOL
I like letting the hot rods be hot rods, if yours likes the EOL's they are lethal, messy at close ranges but lethal none the less;
