25-06 and 257 wby?
 

can a 25-06 be rechambered to a 257 wby? how much trouble?

no one?

I don't have the measurments handy but I think it could be done. Check with Rosko!!! The bolt face would have to be altered. A much cheaper way to go would be just to Improve the 25-06 to AI. The velocity of the two is nearly idenical and brass is much cheaper and easier to find. I believe the 25-06 Ackley Improved casings can be made from 25-06, 270 or 30-06.

ok maybe i should have mentioned this earlier but i am talking about having a tc barrel rechambered, unless someone can tell me where i can buy a 257 wby barrel.

RE: 25-06 and 257 wby?
 

My question is...... why? There isn't alot of difference....seems like a huge waste of money to me. Regards, Rick.

RE: 25-06 and 257 wby?
 

according to chuck hawks :




Cartridge (Wb + type)
MV (fps)
V @ 200 yds
ME (ft lb)
E @ 200 yds




.25-06 Rem. (120 Sp)
2990
2484
2382
1644

.257 Wby. Mag. (120 Sp)
3305
2801
2910
2091
looks to me like there is a big difference. this is using the same bullet weight.

RE: 25-06 and 257 wby?
 

Well to start with,your ballistics for the 25-06 are with a 24" barrel while your 257 ballistics are with a 26" barrel.Since the barrel length will stay the same,You can take 80fps tp 100 fps off of the difference.Then you have to remember that weatherby factory loads are very hot while remington factory loads are fairly conservative.In other words,with both cartridges hand loadedloaded to design pressure with equal length barrels,the actual velocity difference will be around 150fps on average rather than the 300fps in your comparison.

RE: 25-06 and 257 wby?
 

i don't handload. so is it still going to not make a difference?

RE: 25-06 and 257 wby?
 

If you will be using factory loads,the difference will be around 200fps in return for spending twice as much for a box of ammunition.

RE: 25-06 and 257 wby?
 

The 25-06 Improved will add 150-200 fps to the 25-06,

RE: 25-06 and 257 wby?
 

And if you rechamber to 257wby,you still need to figure out if the ejector on your rifle will work,or how to modify it,so it will.

RE: 25-06 and 257 wby?
 

I agree 100% with stubble.
Ammo twice as high and probably not as available.
200 fps increase at the most.
You should get into handloading, it's simple and will pay for itself, you will find it fun and it will open that 25-06 up alot. You would be right with the whetherby.
Doing what you're wanting to do will be a whole lot of trouble for nothing. I say spend the money on some good loading equipment.

RE: 25-06 and 257 wby?
 

I'm actually going the other way. I have a Weatherby Mark V in .257 Wby that while a great gun, I'm tired of buying ammo for it (don't reload). I'm looking for a nice high-end .25-06 to replace it with (Sako, Kimber, Sauer, etc).

RE: 25-06 and 257 wby?
 

Clatton. You won't be disappointed, I made the same move and in the field, I can't see one bit of difference in terminal performance. Most of the 25 caliber bullets are built more for the velocity of the 257 Roberts and 25-06 anyway. I have much hunting expierence with the 250 Savage, 257 Roberts and 25-06. On deer they all work very well.

RE: 25-06 and 257 wby?
 

I guess one question you should also ask yourself is why do I need an extra 200 fps over what a 25-06 can do? Its a pretty fast stepping and flat shooting round as it is. Those that own them seem to praise them greatly for deer sized game. If you are taking shots inside 300 yds ( which is longer than probably 75% of normal deer shots ) the extra expense and muzzle blast would basically give you nothing. On the other hand a 25-06 should be a peach to shoot with little recoil. I would stick to the 25-06 and use the extra money to upgrade your scope to a VXIII or Conquest.

RE: 25-06 and 257 wby?
 

Well I have spoke to Roskoe several times about the 25-06 ai....sweet round. I think the 06ai and the 257 weatherby would be very close. However it would require handloading. The 2506is a very impressive cartridge and ammo is cheapand plentiful.

RE: 25-06 and 257 wby?
 

Twice the money for ammo and twice the punishment on the shoulder. I sold a 257 wby it does have a noticeable kick more than my 300win.

When I was younger I was always trying to get more out of a round than I could and so is the rest of the world. That's why the ultra mags are here today bigger and better they say. You don't need all that, one well placed shot is better than a hundred ultramags.

They only way I would say the 257wby would be any better would be less drop. Less hold and less guess work in the field. But with today's equipment aka rangefinders and knowledge of ballistic's with a lot of practice you might become a animal sniper.

RE: 25-06 and 257 wby?
 

explain what a 25 gibbs is and give details on ballistics

RE: 25-06 and 257 wby?
 

Just chuck it all and go with the 257 STW if you are looking for speed. the 2506 will do anything you want it to do if you set it up right.
With the STW you will get the 3500 - 3700 FPS with the same bullet.

RE: 25-06 and 257 wby?
 

And a barrel life of around 1/4 that of a 25-06.

RE: 25-06 and 257 wby?
 

Was at F class shot on weekend still going on till next Tuesday,some very impressive rigs from around the world, bullet quite popular is 6.5/284 barrel last app:1000 to 1200 shots time to change, just gabing around one famous shooter said about a 257 weatherby Mag by time you get it sighted in the chamber is finnished,
