Effective Range of 257 Weatherby mag.

I have a .257 weatherby mag 24" barrel I am shooting 115 vld. I read in the book"hunters guide to long range shooting" you need 1200 lbs of engery for elk and 600lbs for deer. I ran this through my I snipe program after running the numbers I get 500 yards for elk and about 900 for deer. But I also read some where else that the bullet must be moving at least 2000 fps to expand moving my range in to about 600 yards? What is more important speed or engery.

P.S. My effective range is about 350-400 but each time to the range I am getting more and more but I do not want to waste time or ammo at a range the Bullet will not preform.

We have had no problem shooting 100 grain Barnes ttsx bulets through deer and antelope out to 600 yards. All shots have been complete pass throughs. If you hunt elk with the 257 wby you need to go to the Barnes or swift bullets. The barnes bc is higher than listed.

Thanks for the info 600 yards sounds good, a little out of my range but I might get their by hunting season.

Your not wasting time by practicing farther then your bullet will perform on game. The farther you get good, can make the closer shots easier. If your good at 800 you will be great at 400

Re: Effective Range of 257 Weatherby mag.

The problem I found with the 257 wby and 257 stw is at those extreme velocities all the bullets except the premium controled expansion ones blew into a zillion pieces on contact. People out here are having good succes on long range deer and antelope with the 115 berger vld. But up close at wby and stw velocities there is where the problem is.

I just wanted to add that over 600 yards with the 257 the highest bc you can find would be best. We pretty much call it at 600 or so yards with the 100 grainers. Beyond that they just fall off the table with the low bc's. The wind out here takes them for a ride once you get over 600 or so yards. A good shooter can guestimate it to about there.

The Swift Scirroco 100 grainers have a good bc and shoots well long range in an excellent controlled expansion bullet.

+1….. The 100gr bullet in a .257 Wby is a surprising long range killer of both game and varmints. Heart, Head, Neck, Spine or Lung to Lung... as far out as you can ethically put rounds on target; it well “do” the job. I am and have always been a big fan of Roy Weatherby and you really can't be a big fan of his, without being a fan of the .257 Wby Mag. I've been very pleased with my MkV’s {right now the) .257 Wby Accu-Mark.... but they have to have a 26" inch barrel in my book to make them work.
Just my .02
