Making .257 Great Again

[KoozeDeer]

Hey fellas quick update on my 25x284. I am shooting the Blackjack 131g bullet with @330bc, the bullet is actually made by Sierra and sold from a company called Blackjack who provides reamers and fast twist .257 blanks. I am using a Hawk Hill 1-7.5 twist that was chambered by @NBK. I had only enough RL26 to load 25 rounds. I started slow and worked up in .5 grain increments. The first node I found was at 2930 FPS and it shot 1/2 MOA at 200. I certainly want to look for a faster node, and then I may play with seating depth. As of right now things are looking very promising. And to the 257 Weatherby guys, yes I know it’s a cool round but let’s be fair, the 25x285 with a 330bc is pretty sweet!

will be interesting to see if that bc holds up when you stretch it out a bit. that BC is equal to 140gr 6.5 hybrid burger.

looks like a great gun for the PRS match at camp pendleton https://practiscore.com/smgc-june-p...hBIJHoNXEVhqUH5aDKfQZraCWDXXbvgqHId-5iJ30SOBw

So wondering if the 6.5x284 is a barrel burner what makes them think the
25x284 will be better? one would think it would be worse?

Looking good. What’s the barrel contour, optic, and total gun weight. Looks like It would be a fun rig for coues deer depending on the weight.

Hybrid 140 has a .311bc I believe. And yes, all great rounds are barrel burners

Well my scale said 10.8 don’t know how accurate it may be. It’s a light bull profile, and it has a NXS

i should have said its better than the 140....

 

[Aeon]

nice build... it could be a contender for the SCH cup next year

 

[NBK]

Its a cool rig and should give medium size game a fit!. I have a feeling it will shoot one hole when Chris gets it dialed in.

I like the 257wbymag...alot.

Nicely done Chris,
So it's interesting round.
So I don't know much about it.
How does it compare with the 6.5cm
And does it leave the 308 in the dust.. how about 243...

I’m a big fan of the 243! We killed 4 deer last year with a fast twist 243 Ackley. When compared to the creedmoor it has a higher BC, which will allow it to fly straighter and has probably 3-400 FPS more potential for velocity.

257 Weatherby is my next build for elk and smaller, Sporting weight rifle so I can walk around with it. It was Roy's favorite caliber and combined with old school Nosler partition's produced extreme wound's and one shot put down's.

I have 2 in different configurations....they get alot of practice on large mammals...everything gets dead with a 120grain NP...good night nurse.

The partitions are the factory load load right?

I have a custom 98 Mauser in 257 Robert's and a Commercial Mauser in 25/06.... both safe queens. Haven't shot either one in 20+ years. Fine caliber... Ed F

You own a gun?

I have a collection of Mauser action rifles... I was once fascinated with them. Never killed anything with them. My daughters will inherit a nice collection. Ed F
