New Weatherby Cartridge

[wind gypsy]

Pretty sweet IMO. Unless they are plagued with issues, this is an attractive alternative to 6.5 PRC. Similar recoil, more overbore.

“we’re running a 133 grain Berger at 3k out of a 24” barrel”. Claiming that is a conservative factory load and handloaders can squeeze more out of it with a case capacity of 72.5.

I'll be curious to see the handloading results. I was hitting 2900 fps with 138 A-tips in a 24" 25 creed with 42gn of powder. No traditional signs off pressure, but obviously probably a little hot.

Nice so almost SAUM case capacity.

It’s a smart move. The only SAAMI fast twist 25 is the Creedmoor, but tons of hunters think anything Creedmoor is gay. All the other bore diameters are saturated, but a fast twist 25 is a wide open market with the new bullets out there. Hammer bullets are already loaded in Weatherby factory ammo, so if this is indeed a 25 RPM, I would anticipate some LOOONG hammers being loaded for it, and those require up to a 1/7.5 twist, such as the 127HHT. Hornady has already said they won’t do a 25PRC, so again, the market is ripe for a SAAMI high speed fast-twist 25.

If they really want the cartridge to be a success, they need to allow other rifle companies to chamber it.

We shall see.

Or if Adg or Peterson makes brass for it even without Weatherby support they’d kill it

25 RPM it is ....

I like it!

Was really hoping for a 7rpm the 7mm weatherby is longg and outdated

 

[.284reaper]

Yup - 257 WBY RPM, info on their website.
Sweet cartridge with grossly overpriced ammo.

Yep will never sell weatherby cartridges are a thing of the past, the rifles even more so

Their current marketing campaign is comparing it to the 25 creed and how it's 200 fps faster in similar bullet weights. Not wrong, and that's great, but you're going to get a lot more recoil, long action vs short action and ammo is $99/box for Bergers. I can find ammo online for 25 creed for $32/box for ELDMs. Is the juice worth the squeeze? I don't think so one bit.

Exactly

This is just a 25-284 isn’t it? Q

The 25 RPM is longer, the essentially lengthened the 284 case to make the RPM rounds.

 

[bnewt3]

25 designed for long bullets @3000+ = cool

one place to get ammo = extremely not cool

The recoil tradeoff by itself compared to others IMO is not worth it. 25%+ more powder for 7% more velocity compared to 25CM

In one of the videos they said "entry-level" about the 307..........somebody needs to tell them that $750 for just the action is not entry-level.

They have stated in the past that they really like the 280 AI and they chamber the 7mm Backcountry too now.

 

[MTMeatHunter]

Hate to say it but the 270 win has been pushing 130s over 3k for 100 years in a standard action. Sure, BC matters, but not at the distances most of us shoot at.

I guess if I want the high BC 130s, the 25 Creed gets me way farther than I should be shooting on game anyway.

 

[ACHILLES]

Close, the 25rpm is going to have roughly 3-4gr more case volume than the 25/284.

Attractive alternative! It will eat a 6.5 PRC’s lunch all day every day and twice on Sunday.

The thing is you could make the same or similar argument for every weatherby cartridge for decades but weatherby still exists. Shooting weatherby cartridges as a factory ammo shooter is largely a sucker's choice. Handloading seems more prevalent than ever though and for someone looking at 270 or 6.5 PRC type cartridge that's going to handload, this one will offer a slight edge in performance on paper.

You're absolutely right!
There are still a lot of dudes out there that just want to chase crazy speed and that's all they care about.
"wallop"

Im curious how you arrive at that. with similar bullet weight, PRC has more velocity, a bit lower BC.........likely comes to mostly a wash.......especially @ reasonable hunting distances.

It's pretty simple. The 13X class 257s have higher BCs than 140ish 6.5s and can be pushed faster from the same case. Higher BC, Faster velocity = better ballistics. Sure, you can make up the velocity with a lighter 6.5 pill but you go from a slight BC disadvantage to a more significant one doing so. And the RPM case is bigger than the PRC case so loaded to similar pressures = faster.

Does any of it make a significant different for avg hunter applications, no. But we're bench racing cartridges here.
