Thanks. Did not see it as I rarely look at the small bore forum.

Barrel should be good for a few boxes. :-)

I've recently became interested in buying a couple of Weatherby rifles...but I haven't decided if the 6.5/300wby will take the place of the .257 Weatherby Accumark that I already want...

If all else is equal the 257 will have more consistent accuracy with lighter bullets because it is a 1 in 10 twist and I think the 6.5/300 is a 1 in 8. That would the same as having a 257 with a 1 in 7.8 twist.

I think if WBY put the 6.5-300 WBY and the 340 WBY in their Vanguard they would sell more of them.

Be 24" barrel. Unlikely to become 26" because they want you to buy a Mark V.

340 Wby would have similar problems plus Wby would see people as necking down 375 H&H brass. Lazzeroni (and I sopoke to years ago) brass is a few thou smaller across the base than 416 Rigby to prevent making Lazzeroni brass from 416 Rigby.

As a side note long range bench shooters will us 338/416 Improved and I wonder if that means Lazzeroni brass is shit since Lazzeroni have a 338 which is essentially a 338/416 Improved.

Back to Wby I imagine the market that will buy a 6.5/300 Wby will not be Vanguard buyers. They will be Mark V buyers or custom builders.

A 6.5 300 Wby would be a nice combo with a 300 Wby. In the Accumarks whether standard or Range certified they will be the same barrel contour and same bolt travel. The 257, 270 and 7mm are a shorter bolt travel and a block in the magazine.

I am wondering if Wby is doing development work on a 7mm/378 as in 7mm they are not top of the ladder due to the 7mm RUM.

Not that it matters in the great grand sphere of things, but I've built a couple of 6.5x257 Weatherby rifles for a client. They've worked well. Only thing is, there's not much to choose between that and the .264 Win Mag. God help me, if he hears about the 6.5x300, he'll be wanting one of those next.
There's big, really big, and way too big.

Yeah I was kind of hoping they would fit it in with the shorter .257 - 7mm cartridge length. But from a marketing standpoint I can see why they based it on the .300 length cartridge.

Yes, marketing. But the bigger the cartridge the smaller the. .... oh nevermind...

Would not have happened and because of the 26 Nosler.

Wby now need a 7mm/378 so as to be at the top of the 7mm ladder. Remington is their at the moment with 7mm RUM.

A 7mm/378 would be interesting in the muzzle blast department with 100-120 grain bullets.

Okay,are we sure about the 1 in 8 twist? With that much powder behind it; it just seems to be a pressure problem waiting to happen???

I am reasonably sure but not 100% that they are 1 in 8. However, they will have the conventional Weatherby parallel freebore. I can tell you that it makes difference. I have used 257 Wby with and without the Wby freebore and with the heavier bullets the no freebore 257 could give pressure spikes.

This was a fairly popular 1000yd benchrest number, iirc. Wonder if they come with a spare barrel from the factory for after you find your load?

Weatherby kind of missed the accuracy and precision boat when it sailed about 1997. Accumark never caught on. Like Rugers, nobody ever used their MkV action for precision builds. Savage ate their lunch...
