Home Forums Hunting & Shooting Long Range Hunting 257 Weatherby necked up to 6.5???

I've know of a few guys who shoot a 6.5-06, but has anyone on here ever turned a 257 weatherby into a 6.5 weatherby? I want to build a 6.5 for long range shooting and have been looking at both the 6.5 creedmore and the 264 win. Just curious if anyone on here has ever tried with a weatherby. If so what is the ideal OAL?

Seems like the long way around the barn when you could just load a 264 Win Mag to Bee levels?

When I saw the title to this thread I thought, that would be the .264 Win Mag. I have a .264 Win Mag and a .270 Wby and the .264 is exactly in the middle between the .257 and .270 Wby just without the silly radiused shoulder.

I'd go 6.5 Creedmoor and not look back, for a LR 6.5mm.


Good ballistics, good barrel life, and modest recoil.

6.5-06
139's 142's 141's to 3000 fps + with ease, long brass life and good barrel life.

One stroke though the die of 25-06 up or 270 down and load it.

Simple and to the point.

What are you talking about?! I paid twenty bucks extra to get the Weatherby look on my .220 Extremist. See if I accept any more gifts from you.

Just go up to .277 My more than slightly used Mark V (good shooter though!)

I'm not immune to them, I have a .270 Wby and a .375 Wby.

I really like the 257 weatherby, but the ballistic coefficient on the 6.5 is really amazing. The 6.5, 140 gr accubond has a higher B.C. than the 180 gr accubond I shoot in my 300WSM. I do shoot a 270, and I love it, but once again the .264 has a higher B.C. than the .277. I'm looking for the ultimate long range shooter.

What I'm really looking for here is any information on a .264 weatherby. I need to know the OAL in order to have the barrel chambered correctly.

I'm with you on 6.5 bullets. I gotta come back to the question though. What would you be gaining over a .264 Win mag? Case capacity is nearly identical and brass is available OTC...

If it's just a "would be really cool" thing, I understand that. Have done more than one build that way...

For the Weatherby fans a .270 Wby with a fast twist barrel would probably do quite well with the 165gr and 175gr offerings from Matrix bullets:


165gr with a .7381 BC:

Actually, McWhorter does make that cartridge in their rifle line.

Look at some of the newer 6.5's, like the 6.5 SAUM. Some of those rounds will give the .264 WM a serious race and do it more efficiently.

My 6.5-284 will push 140 VLD's at 3,000 fps comfortably with 48.8 gr. RL-17, maintaining 1/2 MOA precision. It'll go 3,100 fps, but groups open up.

The short, fat rounds will add 100 fps or so to that, which is about all one could expect from a .264 WM, burning a lot more powder.

Should be picking up my 6.5-06 in a few days. You really cannot go wrong with any 6.5 though. Tempted to turn my 243 into a 6.5 Creed...

Did Gre Tan do your 6.5-06 Drew?

yep.

Always thought a 6.5-300 Winchester would rule the planet.Good brass easy to find add the BC of the 6.5 bullet.
Like a 264 plus

Now, that would be a bomb, for sure.

I wonder if a barrel would last through load development...??

It shouldn't be too bad. My 7 Shooting Times has held up pretty good.Actually it's better than I thought it'd be.

6.5-300 Mehhh, too long and a short neck.
