257
Absolutely!!!!!!!!!!!! I've owned several over the years and there is nothing out there like it. Low recoil, easy 500 mtr capable and endless bang/flop kills on sheep/deer/cariboo. I make all my brass from 264 win mag and wouldn't ever think about buying Wby brass. No more expensive this way than any small cal mag to shoot. Both my son and I use RL 25 for some unbelievable velocities in the 257 Wby. RL 25 adds another 200 fps over the old powders I use to use.
I shot a very large barren ground cariboo years back at a paced (before every TD&H had a rangefinder) 421 paces, rifle sighted at 250 mtrs and just layed the crosshairs on his withers and touched the trigger, bang/flop dead, through both front shoulders and everything in between was soup. They are very hard on meat, only downside.
Would only feel like 1/2 a man if there wasn't a 257 Wby in my rack.
They turn coyotes inside out at 250 mtrs, as my son found out last week, nothing salvageable !!
I load mine hot, if I wanted a 25-06 I'd 've bought a 25-06. All my brass is W-W (but Win is going downhill fast in quality) it seems to take abuse better than most other brass.
I highly recommend it as both a fun and devastatingly killing cartridge.
I don't worry about throats, when I wear this one out, I'll buy another, the fun factor more than compensates for having to replace rifle or bbl every 5-10 years.
