New Weatherby Cartridge

[Qholum37]

This is actually looking pretty sweet for a Tikka build. Have almost ordered a 25-284 like a dozen times over the last few days so I am glad I held off. 25-06 case is just a bit long and a 25-284 is just a bit short to squeeze out the full potential of a standard bolt face Tikka. I like it!

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.

I will say that if it's a 25 rpm, if the ballistics are similar to a 6um or 6prc, I could be persuaded to dive into the 25. I would like a screaming hot 6, but nothing is available in factory form and I don't want to deal with fire forming shoulder or neck donuts, or necking down, and would like factory ammo options.

But last I looked, the 25cal bullet options aren't as good and reliably available as the 6, at least for what I want. Maybe that's changed recently.

My only guesses are- it will be extremely overbore, expensive 70-100 a box, and forgotten about in a year.

And we can’t even get tikka to release a 6 cm

I’d say there’s a pretty decent selection now. Berger 133 and 135, Hornady 128 ELDX and 134 ELDM and then there’s the new 133-135 TMK that’s coming from Sierra. Plus whatever big monos there are out there. There’s enough options that I think there’s a place in the market for a big, fast .25 cal to come out.

The bullet manufacturing industry will produce what the owners need if the demand is there.

25 RPM with a slightly shorter case. Real 25-284’sh with a 1-7.5 twist. Stay tuned.

You guys should bombard Weatherby with email requests to sponsor Rokslide so that @Justin Crossley can properly review the newness.

I would be happy to burn up a barrel or two.

Although I will say I have been moving away from the ultra-fast, overbore cartridges over the last couple of years. I am pretty satisfied with what I get out of the little 6.5 and 25 CM these days.

I think 99% of people should be as well.

 

[JD Jones]

With their involvement with Hornady on the 25cm... my bet is a faster 25

 

[AZ_Hunter]

I will very disappointed if it’s another 7mm which a lot of people are saying… the 7 of 1-7 release date.

They already make 25CM barrels so a faster 25 makes sense there too, it would just be a different chamber.

 

[BallisticJesus]

It’s going to be a 25. There are YouTubers and gun writers dropping hits about a new 25 cal all over the place. The only question is the case size. It’s going to be a rebated rim case. Weatherby’s RPM case is just a lengthened .284 case. Weatherby’s teaser pics show the case next to the RPM lineup and it is slightly shorter. So it’s going to be real 25-284’ish.

That sure looks like a 25 cal bullet to me. So the 7mm thing is out.

It’ll be a 25 RPM

 

[Fotis]

My guess fast twist 257 RPM

[gerry35]

25 RPM it is ....

I like it!

“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.

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