Effective Range of 257 Weatherby mag.

[mike33]

Dont get hung up on bc for the 257. I now hunt with a 25 Bobcat { 25 WSM } 100 grain sierra Bt Spitzer 3625 vel. I took an elk last fall with one shot at 450 yards hole was the size of a beer can.

Mike33, I found the same thing. It is so fast and flat shooting it is amazing with the 100 grainers. The bc's haven't been an issue.

Long ranger you have any loads for a 100gr ttsx, in a .257 wby?

While Long Range is coming up with a load; here's one that works great in my rifle.
I would suggest you start 15% under and work up with the "ttsx" bullet. I think you'll find it very usable.
.257 Wby Mag 26" inch Accu Mark
Primer - Fed 215 Mag Match
Powder - RL25 76gr
Bullet - 100gr Barnes XLC BT
OAL- 3.770 {don't seat the bullet to far out}
3800 fps
Case Wby {fired once in the rifle then neck size only}

Good luck

I feel the 100 grainer will handle anything in conus. I cant post the pic frommy cell phone but you wouldnt believe the hole that 100 sierra spitzer blew in my elk.

I shoot 75 grains of magpro with a cci 250 primer and the 100 grain ttsx at 3760 fps out of a 26" barrel wby mk 5.

The sierra spitzers are extremely accurate in mine but were to fragile so I only shoot varmints with them. You wouldn't believe lighting up a coyote with one of those. I have shot deer with them out of my 25-05 imp and 25 Gibbs with good success.

You should try my 25 Bobcat 3600 plus out of a short action.
