257 Weatherby or 264 Win Mag next rifle build

[Double Dropper]

Deer and A

The best would be to go with the one that drawls your interest the most. As stated before the 270 mag. are worth a look too, of coarse I'm a 270 fan so they get my attention just like 35 calibers and other medium calibers. As I thought this over and skimmed over the other post I was leaning to the 264 Win. mag. (it to has a little interest to me, but have never had one). But then as another has stated the .264 Win. would be competing a bit with your 300 Win. mag. and the 257 weatherby cover a bit more of a nitch. So then I was thinking what are your intended use, if for game up to deer I'd go 257 weatherby, if up to elk go 264 win. mag. That's my opinion. So the best answer is in my first statement. Witch ever you go with I think it will be a grate rifle and you will enjoy it for a long time.

Deer and antelope rifle

I have been watching this thread and it seems Crystal clear to me, I'm all in on 264,s. My seven mag barrel went after over 20 years and me having a small frame decided a hunting weight rifle pushing 162,s or bigger hard was more than I wanted. I got a 264 mag 27"barrel and a 6.5prc to hold me over along with 143eldx,s. The Michigan bean fields just got a little smaller.

 

[264 Win Mag Man]

Got to say for me personally, 264 win mag all the way. Drive a 147gr bullet up to between 3180-3200fps with retumbo in a 26" buck the wind harder than a creedmoor or 6.5 prc That's the stuff dreams are made of. Long barrel life is for the fellow who only owns less than a mere 15 rifles.

I have both 257 wby and 264 win mag. I would pick 264 win mag all around,drops deer,elk,antelope where they stand.

Between the two on your list, "my" personal choice is the .264 WM. Just finished head-spacing my budget build and if time allows mount scope this weekend. It has an X-caliber 26" 5R 1:7" specifically built to propel the 156 Berger or 160 Matrix.

Good luck!

Since this post, I now have .257 WBY (1:7" 5R) primarily built to propel the BJ 131s, Berger 133s/135s, and the Black Hole 145s.

The 145s can be a game changer for the .25 cal.

G7 = .371

I took some measurements with the 145s; as seen below, CBTO touching the lands is 2.848" (average of 5) and COAL of 3.441"; I plan on starting at .020" off the lands as the baseline. I have plenty of magazine clearance.

All good options. I have a .257 that's about 50 years old and still shoots lights out. I'm thinking of rebarelling for the heavier bullets, because why not. You won't go wrong with either choice. Lemme throw one out there, since you haven't decided yet you might give a thought to the 6.8 Western. I'm having Fierce Firearms build me a CT Carbon Rage 5.7 lb. rifle with 22" carbon fiber barrel, .277 with 1/7.5 twist. With a 24" pipe It gets 2970 fps with 165 gr Nosler ABLR (2850 with the 175 Sierra TGK) and with the extreme ballistic coefficient and SD it has some legs--it hits like a .300 Win Mag at 500 yards, still producing 1200+ ft pounds at 800 yds. Mine'll be a little pokier with a 22" pipe but I'm goin' for light and handy. I also like the short action cartridge with less free recoil than a 7Lb 30-06 (allegedly, that light carbon rig may bite a little more than that, physics being kind of hardheaded). Just a thought.

Feenix is that 145 a bore rider design or is the bearing surface extremely long? Interesting looking boat tail design.

While the 270wsm/ 6.8 western is a fine cartridge especially with new high bc .277 bullets and capable of killing anything in north America.

It has no similarly to a 300win mag or any magnum 30. A 215 berger at 2950 just beats any 165-175 class .277 projectile at 2800.
The win mag will also have twice the recoil of the western but 150% of the energy at 800 yards.

The corresponding tables are for the 215 berger/300 win mag and the 6.8 western 175 tgk.
10 mph wind.
As you can see, not very similar

The 164 Win Mag with H1000, 140's, gives very, very good barrel life. Not so much with most other powders.

H1000
N160
N165 are very cool burning powders.

I have had half a dozen 257 Weatherby's with custom 26" barrels and short throats. 100's at 3850 using R#22 shooting sub 3/8" groups is real world, and 115's at 3600 is the same. 100g TTSX, 115g Berger, 110g Accubonds Always please when it comes to accuracy and the way deer and hogs just flop in their tracks. Now, light up the 80g Barnes TTSX at 4150 with R#19. With a Gentry muzzle break, you always see the bullet impact the animal, a very pleasurable gun to shoot!

It's a rebated boat tail design - http://corbins.com/rbt.htm
