What can beat a 257 Weatherby at a 500 yard shot at a Pronghorn? and Why?

A .50 BMG.

50/20 Anzio.

The Guns of Navarone.

Super duper top secret Naval Rail Gun.

6.5 Creedmoor

Now you did it....

Cue BOBs.

THIS^^^^^^^

Reason: you don't even have to actually hit the antelope. Just get it close to its nose and it'll suck the air right out of it with 0 meat ruined.

No 6.5/300 Wby answer yet? Well ok then....

The classic 264 win mag, might not be far behind.

I'm at a loss then, I have and shoot a 256 Newton 257 Roberts, 257 W., 264WM, 26 Nos., and a 6.5 X 300 W. I will admit though that my 257 W is what I use when antelope hunting.

Well it’s a good one. I would say the 6-06 with 26-inch barrel and 80-105gr bullets would be quite ideal for pronghorn out past 500 yds. Just as flat shooting with less recoil and muzzle blast.

The German 'Paris gun'. It had a range of about 81 miles. Death from the stratosphere.

.458 Lott

Why?

Beat it in terms of what - drop, drift, or retained energy and velocity?

Using Weatherby ammo data for 500 yards:
2514fps = 80g TTSX
1419fps = 115g Ballistic Tip
-17.4" = 80g TTSX

Weatherby sells their Mark V and Vanguard .257 rifles with 26" barrels. Their ballistic data corresponds well with my calculations for the 80g TTSX at 4000 feet in altitude.

If we assume the 80g TTSX (B.C. .316 per Weatherby) is adequate for antelope at 500 yards with 2514fps, 1123fpe and a drop of 17.4", let's do some calculations.

The first is that drift will be about 16.8" in a 10mph wind.

My 24" 6.5-06AI pushes 140g bullets to 3075fps with a 24" barrel. Assuming a 26" barrel and a 143g ELD-X (B.C. .625) at 3100fps, 4000 feet altitude, same 300 yard zero: This is a non-max, accuracy load.
22.3" = drop
10.3" = drift
2452fps = velocity
1909fpe = energy


I'd say that beats the .257 WBY pretty handily. I'd much rather deal with an additional 5" of drop than 3-1/2" drift.

If the 6.5-06AI had a 26" barrel with max loads the advantage would be even greater.

The .%$#@57 is the real way to go.

IME, very low S.D. bullets, like the 80 gr Barnes at hypervelocity, sometimes have bizarre terminal performance on WT type game.

It may not work out like you would think.

Beware.

26 Nosler

I've had a .257 Wby and a 26 Nosler. Still have the Nosler.

DF

Still have both, son likes the 257 wby.

My 257 was accurate, just had problems with consistency. That MkV action now wears a #3 Brux 7RM and sits in a McWoody Wby Express, formally the Sako Safari (Wby inlet). It is glassed and free floated with a Timney trigger. Tack driver. Sold the 257 barrel, dies and brass.

DF

1 gauge tri barrel!! Top it!!!

Easy, George Jetson four barreled pepperbox pocket derringer ray gun. ; ]

On a serious note, the old 7mm STW and 7 RUM chunking 140gr NBT's at 3600 will spank that 257 wby's little ass as far as non-twist straight flat shooting cartridges go.

Lightsaber

.257 STW

6.5-338 Lapua AI for the throat torching WIN.

.257/.378 Wby would be a real barrel burner also.

Nice looking stick DF.

Yup, bout a hunnert rounds would have you on the phone with Bartlein.

Bartlein makes barrels 5 days a week.

How about a .257/.300 Wby?

I've heard it's not overbore if you can find slow enough powder.

Wonder what that round would perc best with?

DF

Hydrazine!

I'd want a long trigger string...

DF

I'll watch from the house ;]

WC-872

Cells jacked up and in another bag of dry rice, I heard it buzzing and saw it was you, got it wet again.

Nitro soaked BS.

Charcoal is slow enough!

2.7 mm kolibri

The 9.3 BS is mo betta

I would think anything built on the rum case. All the nosler line and the long action rums with larger bullets. I'd think just less drift to deal with. Inside 210 swift scirocco at 3250 or so out of 338 rum. Hammers them. Longest is 532 a couple years ago. 515 this past season.

The fact is that if drift is the nemesis to beat, there are a bunch of cartridge/bullet combinations that will beat the .257 WBY at 500 yards.

The .257 WBY can shoot flatter than most cartridges out to 500 but will lose in retained FPS, FPE and/or drift. Pick your nemesis.

6.5 Creed comes out.... and everyone forgets about the dominance of the B-29....

A friend of mine bought this 50 caliber AMAC sniper rifle and thought it would be fun to go hunting with it. 50 BMG is not a good animal killer. We shot an antelope with a 550 grain soft point and the bullet didn't open up on the antelope. It did slow him down to where Russ finished it with a 45-70...

To me the 257 Bee was a rockstar before accurate range finders and scopes that dialed accurately really took off in popularity. The 257 allowed a guy to sight it in with a MPBR of 400 without too much difficulty. But if a guy wants to really shoot past 400 with any regularity a reliable scope, a reliable range finder and a bullet that bucks wind really shines and that ain’t the 25 cal bullets strong suit. Add the fact that you have to use 30-40% more powder in the 257 as well as barrel wear and it’s really just another option but not the best option IMO. I live in the eastern plains of CO and there are Antelope everywhere but it’s also windy on 9 out of 10 days most of the time, taking 500 yard shots with a 15+ mph wind is gonna make stuff challenging with low BC bullets!

Thats right, you owned a Rem700 in 257ROY. could not figure out how to reassemble it if I remember correctly. Must of bad mouthed the rifle and not the cartridge;)

LOL. That you Jake? You in NC now?

Wouldn't you know it, Hope you guy's are all doing well

TFF

The 257 is a great round, flat, hard hitting, damn little recoil. It’s hard to beat!

24/378

Anything Lazzeroni. What? It's the 21st Century already? Dammit. Then a 22 CM shooting 75 ELD's and any decent RF.

Now after 52 responses, aren’t you sorry you asked?
