Which Weatherby Caliber?

[Jimmy33]

.257 is on my list also...

Any thoughts on the 6.5 RPM?

Its newer so I havent had as much time to research it yet...how does it stack up against the 6.5-300?

I like Weatherby cartridges, the company has developed cartridges in most calibers with flatter shooting ballistics than standard cartridges. What this means to me is that I can hold dead on an animal at a further distance than standard cartridges. Often times you get only a couple seconds to take a shot before an animal turns away or simply disappears into the vegetation. I can simply hold dead on and shoot the animal at greater distances without needing to compensate or fumble with dials. I don't care if the cartridge costs more money, I don't care if the rifle barrel only lasts for 500 to 1000 rounds, what is most important to me is that I made the shot before the animal disappeared. The icing on the cake is that Weatherby cartridges deliver the same bullets with a lot more energy at the same distance as other standard calibers. So not only do you hold dead on at longer distances, your bullet has more knock down energy when it hits the animal. I don't think it makes a huge difference between 6.5 and 270, I think with either of them you can hold dead on at a further distance than their contemporary counterparts and make more kills because of these two reasons combined!

the velocity difference between a 6.5-300 weatherby and a 26 nosler isn't enough to spit at and if you hand load it virtually disappears. Factory examples below.  I helped a gentleman the other day at the range chronograph his weatherby with with the 127's and it was 6 shot average of 3496 with an es of 37. New rifle though so I'd assume once it settles in that 3531 will be fairly spot on.

Shoot what you want though and when in doubt buy 2

6.5-300 case holds 98 gr of H2O  6.5 RPM holds 82.5

I wouldn't consider the 26 nosler to be a contemporary cartridge, it's another one of the new gang of cartridges on the block. The ballistics of the 26 appear so similar with the 6.5 wtby that it's more a choice of who builds the gun that feels the best to the individual.

Ammo and component availability as well. That was the point of my original post. Too many other chamberings out there that do it as good or better for me to ever buy a weatherby head stamp anything but if a guy wants a weatherby he should buy a weatherby

[bearpaw]

  agreed, a matter of preference

I have to agree  If I were to buy a weatherby again I think it would be a 378 variant, 30 or 338. I'd have to hold them again to decide

Can’t go wrong with a 257 wby mag. But I really want that 6.5-300!!

[Shoofly09]

Im a big fan of the weatherby 270 for deer and elk, with 150 grain nosler partitions.   Ammo's not cheap, but I don't shoot much.

As Bearpaw stated, pretty flat trajectory.

6.5-300 meateater edition.

While I have carried a 300 Weatherby mag, that 257 is hands-down my favorite. It was Roy Wetherbee‘s personal favorite too. I’ve taken several elk and a handful of deer with my 257, the speed and shock of that bullet In any weight, just puts them right down.  And yes,  it is a flat shooting son of a gun! 

I’ve owned my 257 since I was 19, and I’m in my 50’s now.  It’s a beautiful early West German with an original Sauer barrel.   But man does that thing have some heft!   

I only take it for a walk on sunny days now,   My all weather rifle if the Tikka in 30.06.   Seems like half the weight of the weatherby. 

[str8meat]

I have two 6.5/300’s like them both, but the ultra light weight goes with far more than the accumark. I cannot attest for the 270 wby, I can only compare to my 300 wby. I really like the 6.5/300 wby

[yorketransport]

Go with the 6.5/300, everyone needs a moderate velocity 6.5mm. When you decide you want something better you can ream it out to a 6.5 RUM.  Then you'd be shooting those 127 LRX bullets closer to 3700 fps.

I'm not much for factory guns in factory chamberings, but a Mark V Backcountry in 6.5/300 Weatherby would be a pretty nice setup.
