257 v.s. 270 weatherby mag

Which gun would better all around between big game? I was wondering about ballistics between the two guns. I do like the 270 because of the different load options, but i hear alot of good news about the 257. I am going to mostly be shooting deer with this gun.

Both will kill any deer if you're close enough to put a bullet into it's vitals, whatever range that may be as your skills allow.

This moment is a paradox, it's the oldest you've ever been as well as the youngest you'll ever be.

What Horsager said...

the 257 shoots a 120 around 32-3300
the 270 shoots a 130 to roughly the same speed.

The main difference is BC and TKO(from the larger diameter)

If you are going to have a pure deer/antelope rifle with maybe a few coyotes on the side. The 257 is your caliber. Like they said above, anything larger go with the 270 for versitility.
My 257 is my go to deer round. I can't think of needing anything else.
Supposedly Roy Weatherby used his 257 for cape buffalo. I know I would never go that far, maybe because I would never be able to aford it! ;-)

The 100gn TSX is "THE" bullet to shoot from a 257Wby. Our steel targets are so hard that brand new drill bits in a press won't really even leave a mark on them. At 200yds the 100gn TSX from a 257Wby popped a much cleaner hole through the target than did the plasma cutter we used to make hanger holes. That combo is some kinda wicked!

Not every rifle tunes to a specific bullet.
In all honesty, I have tried barnes in half a dozen rifles.
The best groups I have ever gotten from them is around 2 inches... which is needless to say pitiful. The etips are NOT much better.

I'll stick with a hotcor, bonded or a standard nosler/seirra... I have had the best tuning luck with standard everyday bullets.

I should rephrase that..
I have had my best luck NOT using copper clad alloy bullets or expanding solid copper projectiles.

I would however like to try GS custom bullets... But I'll be &(^() if Im going to pay 2$ a bullet from south africa.

For the TSX to shoot well in my experience you either gotta engage the lands a bit or back off their recomended .05" or more.

Hard to fathom they are THE most accurate bullet in at least 15 rifles between pards and myself and you can't make them shoot too. TSX is an entirely different animal from the X or XLC.

Kimber Montana's in 243 and 7-08
Rem 700's in 25-06, 280, and 7-08
Wby Vanguard in 7-08
Win 70's in 257Wby (custom tube), 270Win, 300Win mag (x3)
Wby MkV in 300Wby (custom tube)
Tikka T-3 in 270 WSM
Ruger 77MkII in 300WinMag,

A fair representation of a good portion of readily available factory rifles with of course the two noted exceptions.

Ive played with the TSXs primarily...
Ive done their reccomended,max oal... you name it.. I have yet to find a combination that will function... the latest has been the 270 win..
Heck that bullet has completely different harmonics than a standard lead core bullet, which is understandable.

The best I found with the 270 with that bullet is a stiff charge of rl22 with a wlr. I found that 60gr of retumbo and a 130 ballistic tip does sub moa ~.7in all day long.

Not too mention, at the price of the barnes bullets, you surley are not getting your moneys worth out of them by plinking paper or harvesting bambi.

Id be more than happy to use a TSX on an elk or some other heavy boned critter.

What are the specs of the 270 win load you ran the 130 tsxs with?
