25-06 versus 257 weatherby

My father passed away and left me a rem700 ADL in 30-06 with a bushnell scope. It has been sitting in the safe so I figured I should do something with it since I will never get rid of it but definetly dont need another 30-06. So I have been brainstorming on what to build. I decided on a 25 caliber since I dont have that flavor and was looking through the Nosler reloading book and it shows that the 25-06 with a 24" barrel is 100+- Feet per second slower than a 257 weatherby with 10 grains less of powder. Is this right? I am just going to use the action off the ADL and the rest will sit in a tote. I am going to put a 24" Lilja barrel in#3 and a classic turkish walnut stock and use it as a gentleman's rifle. Any thoughts on twist rate? I am thinking 1 in 9. Appreciate responces. Thanks

Re: 25-06 versus 257 weatherby

A 1:10 twist is sufficient for either, if you want to stick with a 24" barrel the 257wby will not reach its potential of 3-400fps over a 25-06, a 25-06 or 25-06AI will work better with a 24" tube but if you go with a 26"+ barrel the wby is way more powerful and the norma cases weatherby uses can be reloaded way more than any 25-06 brass.

Re: 25-06 versus 257 weatherby

If you do the 257 wby in a 26" barrel you are way faster than a 25-06. Loading manuals give you a good place to start and that is about it. Particularly with the wby calibers where they way underload them because some rifles do not have the wby freebore. You will need to open up the bolt face to do a magnum cartridge. I would suggest going to a 6.5-06 improved with the action you have. Way better bullets in 6.5 than 257 to hit harder at longer ranges.
Predictions are difficult, especially when they involve the future

Re: 25-06 versus 257 weatherby

I'll play the devils advocate here. There are a couple of reasons you might want the 25-06 instead of the 257 Wby. Cheaper to shoot...Wby brass is damned expensive, and less powder per shot with the 25-06. Less recoil...not much, but some. No messing with the bolt face. With the barrel length being equal, you're really not giving up much velocity and the animal really is not gonna know the difference in impact energy.

I had the same decision a while back. And like you I chose a Lilja #3 10 twist in 25 cal. And I struggled whether the .25-06 and .257 Wby. But I decided on the .25-06 but went with the .25-06 AI. Couldn't be happier. I kept the barrel as long as possible and it finished at just over 27". And now I'm not losing hardly any velocity at all.

Re: 25-06 versus 257 weatherby

Great choises either. I tend to shoot a 25-06 more than any other caliber with a 100 grn Nosler BT. Its worked on everything from Couse to Elk to Sheep out to 540 yards. I have a 257 Wby as well that I am shooting heavier pellets in but just seem to use the 25-06 as my go to rilfe. You will get up to 200 ft quicker out of the Weaterby same barrel, bullet etc. . . The idea of the 25-06 AI is probably the best.

Good Hunting.

Re: 25-06 versus 257 weatherby

There is one other option as well, it'll run head to head with a 25-06AI with less reloading headache and you can use norma or lapua brass and that is a 25x284win. I have seen this round sling 100grn NBTs @ 3400+ from a 26" 10 twist. Just a thought.

I have been using a 257 Wby with a 28" barrel and a 1-8 twist barrel with good success on elk.
