as do I.

The 6.5 300 Wby is a very hot rod round. It runs a 140 grain about 3300-3350 fps with about 85-90 grains of powder. If you look at the newer 6.5 PRC, it runs a 140 grain at 3100-3150 with about 59 grains of powder. The Wby round is certainly more expensive and is not as a good case design. I have had trouble getting some aggressive high BC bullets to shoot well in the 6.5-300. The 143 ELDX and 140 AB have done well though. The new PRC is pretty sweet. I'm liking it! Even the 6.5 GAP 4S (or 6.5 SAUM, same thing) works very well.

Stainless SPS 26” barrel, pretty sure Remington didn’t offer the 257 wby in a 24” in any configuration SPS or CDL SF

on paper I do like the 6.5 prc better than the 6.5-300


kinda like putting a 454 big block in a VW bug......

You say that like it's a bad thing. Sounds fun

And this is where we keep playing tick tack toe. Some of y'all are wanting to push 140+ , while some of us are happy pushing 115's and 125's and getting out there in the 3500 plus range. I want a 1-10 twist and that makes allot y'all high BC boy's just cringe. I was alive for the birth of the 264 and it's death in 1962 when when the 7-mm Mag was born. I'm not going to take anything away from the 264/6.5 other than the lack of bullet selection at the time. But I will say this, since the early 40 I've watched everybody in the industry play catch up with Weatherby.

Catch up out of the gate. They have been far surpassed a bit down range.

Little ole Hornady casts a giant shadow on stuck in their ways Weatherby in 2019, when it comes to bullets and ammo.

“You failed to list a gun that competes with the 257 Weatherby in the Quater Bore world.”

If the 257WM is coming from a 24” barrel, the 25-06AI out of a 24” barrel is a pretty good match for speed and the 25-06 brass is a whole lot cheaper.

If the 257WM uses a 26” barrel, then it is hands down better long range cartridge, if speed is your only concern.

Why a use a.257 bullet? The .264 bullets available today are far superior in sectional density and BC.

Personally, for long range I must prefer the recoil and down range performance of a 6.5-284 Norma.
.
The 6.5-300 and the 26 Nosler will outperform the 6.5-284 for speed, no argument here.
However, until those calibers start winning 1000 yard matches I prefer the accuracy of the 6.5-284.
The 6.5-284 has won 1000 yard matches and will not break your shoulder or the bank when compared to the afformentioned 6.5s.

It seems everyone is going 6.5 creedmore crazy at present. The creedmore cannot do anything that the
6.5-284 can do except go slower, deliver less energy at extreme distances, and fit into AR length actions.

For the 6.5-300 recipes- were some of the bullets that didn't perform well the 147 ELDM and 140VLD? I saw wby is now loading the Berger into their premium line of factory ammo. Did you try anything heavier like the 150SMK?

I think the point, or at least my hope for the 6.5-300 would be to push a high bc bullet FAST to minimize vertical error and still provide as much energy to the target as possible. That was why this intrigued me to begin with.

And this is where the game goes from X to O no matter who moves first. I'm not about to try and run a 147 or 150 grain round out of a 6.5-300 Weatherby. Probably the heaviest I'd run would be a 125 and have it flat lining out to about 500 yards, beyond that I have no interest in taking the shot. If I need 150's I'll run a Nosler Partition out of my 300 Weatherby at around 3550.

Both John Wayne and Ronald Regan shot weatherbys.


For what it’s worth

I do own more than a few long guns. In that collection are several Weatherby rifles.

Vanguard - ( 243 rechamberd to 6mm-284 )
Vanguard - ( 30-06 )
Vanguard. - ( 7mm Rem Mag )
Mark V Euromark - ( 300 Weatherby )
Mark V Deluxe. - ( 378 Weatherby )

All fit me well. The Marks a bit better than the Vanguards but all better than my other factory rifles.
I am partial to the Weatherby Monte Carlo stocks I guess.

My Vanguards have been retrofitted with Timney triggers.

All will shoot sub MOA with handloads. My Mark Vs will shoot sub MOA with factory rounds and the 378 is more acccurate with those loads than the 300. Curious to note the bullet drop between the two are very similar.

The 378, (378 WM was the parent case for the 460 WM) is a flat shooter with tremendous energy at the target.
My 378 will clear benches either side of it at the range. It will blow the dust from the rafters as well. It has a custom muzzle brake and the recoil now is similar to 200 grain 30-06. That makes it bearable for my 67 year old shoulder.

The 6mm-284 is a hoot to shoot and I highly recommend that rechambering if one’s 243 is getting a bit long in the tooth. Mine will hold sub .5 MOA and is a bit faster than a 243.

From what I have experienced the Japan manufactured Mark Vs have a superior quality action than the USA made ones that I have racked. The bolt fit is tighter side to side and does not feel sloppy in comparison.

Some Weatherbys will shoot and some will not. Just like some barrels like certain bullets better than others. If you own one that will print you will love it and swear by it.

Just my 2 cents.

My choice would be 7mm Wby. But, a 7mm necked down to 264 would not be a bad choice.

The 6.5 x 300 Wby is overkill.

Why neck down the 7mm WBY .02 inches when you can neck up a 257 Wby .007 and have the same thing

WELP- there is a .257wby sitting in the safe.... LH, Rem 700 custom, couldn't pass it up. Waiting on rings to show up and hopefully I'll have it at the range Wednesday!

Somewhere out there, Roy Weatherby shed a tear.....

Couldn't pass it up! Just aren't enough LH offerings- a Mark V LH is still on the list- but will have to wait for now.
