.300 WBY with the "cheaper" 180 Norma bullets will run 3200 and drop a whitetail like a sack of taters. 200-250yds like a lightening bolt. That's my favorite cutover cartridge. So will the same ammo in .257 on whitetail. Still like $40 a box though.
All that being said the best terminal performance on Whitetails in any cartridge I've used are .35 caliber. If I was only shooting 200-250 I'd take a Whelen over any of them.
I have a 35 Whelen AI I load with 250 grain hornady round nose bullets. Drops deer like the hammer of Thor.
